Pros: My previous experience with group real-time communication was IRC. As an employee who had just barely gotten their toes wet using terminal, IRC was intimidating to run and intimidating to find any past conversations because searching it required terminal commands and a third party plugin to just login. It also did not retain history when you signed off, so as one who is on a team that includes people in no fewer than 3 time zones, I often missed communication when I went home. It took some prodding to get our team onto Slack, but once we were on all, we didn't look back. Slack's support of custom bots was, ironically, one of the determining factors for migrating, but we heavily use the drag and drop interface to share files and images all the time, and also push out GitHub notifications from cli testing into our channels. Being able to pin resources to channels and having the little channel blurb at the top has also allowed us to sub-divide into teams and have critical resources for each team (ticket tracking, zoom link, etc) at the top.

Cons: I'd say the one downside I feel about Slack is that while they did do a good job improving their search, I still find myself struggling to find things I know I favorited and I can't search favorites. I also wish I was able to tag favorites with my own set of tags.

Overall: We use Slack as an internal team communicate tool for transparency of discussions with team members in multiple time zones and also to encourage team bonding. Direct messaging is also conveniently located here and since most of the devs on my team don't actual bother to login to the company mandated direct messaging team, it's easier to get ahold of them.

Pros: This is a great and easy way to communicate with staff and employees, especially if this a remote company or you have workers or work remotely. You can set up different channels to keep conversations organized, which also allows you to customize who can see each channel. There is a great new feature that allows you to be invited into another company's slack channel, which is very helpful if you work with different organizations. (this feature only works if both companies have the paid version) Another pro is that you can share anything through slack such as files, videos, pictures, zip-files, etc. This is a fast and effective way I communicate with our web designer by sharing photos, videos, urls, files, and more. The best feature is the app. I download it onto my Iphone and don't miss a thing. It also will notify you if you want to when a new message is posted. The app is so easy to use and functions just as well as the desktop version.

Cons: One con of this software is that if you have the free version you only have a limited amount of storage. If you do not send a lot of files and documents than this version should be fine. You can delete files if it gets close to reaching the storage maximum, but if you use this on a daily basis I would recommend buying the premium version. This gives you unlimited storage and space. Also, I wish that new feature of adding other companies to different channels externally worked on all slack versions, not just the paid version. This is a great feature that everyone would love to use.

Overall: Overall, this is a great way to communicate in a work place for all sizes. If you are a new business and want to test this out I would highly recommend doing so. I know several organizations that use slack and I have never heard a negative review about this software.

Pros: The thing that I like the best about the Slack software is the fact that even the free version of the application (which is the one that we use) has an abundance of features. The biggest drawback of not paying for the software is that older messages are not archived forever and will be deleted as space is required. However, I have found that there is months worth of conversation still stored in the app, which for our purposes is more than enough.

Cons: The thing I like least about Slack is that a lot of the extensive functionality, such as polling your users, is done through third party widgets. While this does make for an extensive list of things that you can do in Slack that's too much for the developers of Slack themselves to realistically keep up with, the quality of these widgets are varying and you sometimes have to search through and then test out multiple ones before finding one that works perfectly for your needs.

Overall: My overall experience with Slack is that it is a very solid virtual workspace for your team. It does seem more geared toward workplace functionality than other similar options such as Discord, which seems to work better for gaming. The control that an admin user has is unparalleled, and it makes file sharing a breeze. The free version is more than ample for any team at work that doesn't want to jump through hoops to get their organization to pony up for the full version, and feels complete as is and not like you're constantly being bombarded to upgrade. There are a few drawbacks such as such reliance on third party widgets for some functionality, but even that is a mild gripe and the army of available widgets to choose from makes up for it. Slack is a great product.

Pros: The best thing about slack is , it keeps you updated with the team collaboration with updated features where you can make your work done.

Apart from that Slack gives you a status feataure to write about yourself for a line or 2 lines sentence. When you are communicating with someone then he/she can see your status sentence. You can edit or clear your status by clicking on your name to the top left sidebar.

Another feature which I liked is when you slack messages are loading there is a random person's status is loaded infront of your screen so that You can get to know about his/her slack status.

Before proceeding for collaboration with your team or person, slack provides its SlackBot to get started with Slack basics so that you can have proper idea to use slack.

One more thing I liked is, slack gives you the notification feature for giving you updates regarding slack messages. You can send messages to yourself which will not be vanished from your slack account. This way you can keep important messages to your personal chatbox.

If you send a piece of Code then it will convert automatically to that code format to understand easily.

Cons: Whenever your message is read by someone, then you will not know if that person has read your message or not.

After sending messages to a person, and if a person has not read the message , and you delete the message then that person won't be able to know what message you have sent.

After sometime (Appox : 10 days) , the slack conversaion gets deleted from your account unless you don't have subscribed.

Voice Communication needs to be there in Slack.

Also there are no calender and documents features in Slack.

It uses more memory in Desktop.

Task assignment is yet to be there.

Overall: I would like to say that for team collaboration and channel managment, you should definitely go with Slack. There are so many benefits I have got by using Slack.

Pros: Slack makes the workflow easy by providing the necessary tools to stay on track with projects. Here are some of my personal favorites from its rich toolkit: clustered unread messages; marking messages as unread to return to them later; scheduled reminders (to yourself and others); starred items; threads; ability to integrate Google Drive, Jira, etc.

The reminder feature is a lifesaver. My daily tasks sometimes reach ridiculous numbers, so the friendly Slack bot always helps me remember about important weekly meetings or updates that I owe to different teams.

Threads are an essential component of my workflow as well. As I actively communicate in more than 30 different channels across the company daily, for me keeping it clean and having comments gathered in one place is very important.

Status updates make it very easy to see if a person is out of office, and the recent option to set a specific time period for the vacay status makes this feature even handier.

I've also used the call feature for my overseas conference calls and it has been quite useful as well, especially when you're used to taking notes right in Slack.

In terms of interface and functionality, the software is very clean and simple and is very easy to use. Channel setup, settings and search system might be a bit complicated at the first glance, but you get used to it once you poke around a little.

Cons: I have experienced some connectivity and slow loading issues with Slack and those have probably been the most inconvenient issues to deal with. Aside from that, Slack notifications sometimes tend to be quite intrusive and can really distract from the work at the moment, especially if you have many people messaging you at the same time. I have figured, that disabling the popup notification helps a lot in this case. Having only the badge with notifications count on Slack icon makes you feel a bit more free in your actions and allows to get back to messages whenever you feel that you are done with your task at hand.

Overall: Working at a company that has 300+ employees and offices in 5 locations worldwide, it is essential to have a platform that allows for flexible communication on various levels, starting with 1 to 1 chats and small group conversations, ending with team & global company channels. I started using Slack almost 2 years ago, and it has been an inseparable part of my work since then. It is simple enough to start using right away, but at the same time offers a wide variety of features and tools to get things going fast and efficient. Overall, it's a great experience and well worth the money if you're considering this for your business.

Pros: Slack has incredible integration capabilities, and can connect to a large percentage of other project management and operations software applications. Our of office, for example, we utilize its connectivity to Pingboard, JIRA, and Zendesk to make internal communication both thorough and seamless. It also has great external communications capabilities, and you can set up multiple teams with in a single application, and give each team its own individual permissions settings. On the lighter side, Slack offers fun and entertaining features such a giphy integration and surveys/polling, which are frequently used at our office.

Cons: Slack tends to have intermittent connectivity issues, which can be detrimental to workflow, especially if your company has remote employees. My company experienced several service interruptions over the past year, where Slack has gone down for multiple hours at a time, forcing us to resort to other means of communication (email, phone, Google Hangouts, etc.). The quality of Slack's call capability is also spotty, at best. I regularly choose other means of voice communication because I have consistent concerns about the audio quality of any given conversation taking place over Slack phone.

Overall: Overall, Slack is a top-tier messaging application with a lot a fun and practical capabilities. The Slack mobile app is also very well built and user friendly, and integrates nicely with both Android and Apple operating systems. When compared to other IM applications we've used such a Google Hangouts or HipChat, Slack proves to be the superior and preferred interface in terms of both quality and feature capacity. I would definitely recommend this application for both business and personal use.

Pros: This slack is great for real time group discussions and it has large varieties of the integrations which includes different varieties like Google drive and it has capabilities to include large number of people to communicate at same time. Almost all the big and small organisations are utilizing in expanding their business strategies and productivity. The best of slack is it has an option of the private chat group where only the authorized and permitted members can join and have secure communication. Slack has large variety of the options like snippet exchange file exchange and we can easily create slack bots for our communication with all the elegant features. it sends the push notifications to mobile if it founds message is unread for lot amount of time. I recommend for all the companies to utilize and expand growth in business slack will be best tool it is easy simple secure and with less cost.

Cons: The least of this software is there is no calendar which is what we are expecting in the next upgrade a part from that there is no voice call features to communicate. Looking for the preview options in the slack as every time the files need to be downloaded from slack a part from that if there is a preview option the file can be made with pdf this could be much more helpful

Overall: High Availability: it provides multiple modes of the communications. we can setup channels for the specific topics send messages directly to one and many at same time

search function: one place we can search all the required apps rather than nesting in different tools

Ability to share emoji making the communication funny and attractive.

Best UI and all the required apps at one place

Pros: I don't remember how my team communicated before Slack. It keeps my coworkers connected in and out of the office. It cuts down on our emails and makes communication easy. There are a lot of apps and integrations that can be added to automate processes. You can integrate project management tools, Google Docs, Spotify, Canto DAM, Giphy for some fun with coworkers and so many more.

I love that I can drag and drop files, images and videos into slack to share with my coworkers. In addition, slack allows free integration with many other tools out there. My peers who are software developers talk about how easy it is in the backend for integration.

Slack is easy to use and has great built in functions for notifications. It has really been extremely helpful to get multiple departments talking at times and keep each department informed while not in the same location. The ability to upload files makes it easy to share ideas.

Cons: The Screen sharing could be improved, along with mic recognizing.

When network connectivity is lost during screen sharing or calls, the reconnect feature doesn't seem to work really efficiently.

My biggest complaint is that Slack makes you way too available. You're expected to know whats going on whether you are at home sick or in the office working.

Sometimes the app on the phone won't clear your notifications even after reading or checking through them.

Overall: We can definitely communicate with almost no exceptions. It takes the "where is this person" out of the equation as you can just send them a message and know when they come online and see it. The benefits to not just sitting and waiting on an answered email are endless.

Pros: Once you get the hang of it, it's really well designed, easy to use and really fun. They have so many integrations that make it easy to customize it for a company and yet let each individual employee personalize it for themselves (names, gifs, emoji's, etc).

It's a streamlined way to get a simple answer back or stay in touch with employees you don't happen to be sitting next to. You avoid email overload.

Cons: It can be a HUGE time suck and it was very hard to be off slack at any point.

This is probably company dependent, but I was as a tech start-up and it was so easy to spend hours of my day messaging people about work or non-work related topics. This can be fine, unless you're trying to get something meaningful done. People would slack during meetings rather than be fully present. That made no sense to me -- if you're going to be in a meeting, BE in a meeting.

I also felt like I couldn't get off slack on nights and weekends. Again -- that's a company wide decision, but there was an aspect of slack like texting that made people felt like they had to respond when they got a message. Even if you don't respond, it still drives up anxiety to have notifications pop up.

Overall: We used slack as a company both to facilitate communication across all teams (a tech start up that grew from 20 people to 120 people while I was there) and run basic options (e.g. submit bugs to the product team).

It helped us build a strong culture of bonding over personal news broadcasts and basic company updates, and also improved our productivity in certain processes. In other aspects, it was definitely a huge distraction. I would say it's worth integrating with clear guidelines for etiquette.

Pros: We work in distributed (software) teams for more than 10 years now. We always had the need to communicate synchronously and asynchronously and used a lot of different tools, as for example Skype or all kinds of other text/voice chat solutions. It all worked okayish. The issue was, none of the tools were able to give us the whole bunch of features (and do so conveniently). You want to chat via text, you want to make calls, ant conference calls, and you wish to share your desktop, ideally throw a couple of files at your colleagues. Also, wouldn't it be great if you could mark things your colleagues said and make your chat program remind you tomorrow. Or remind someone else about something you said or generally do simple task handling inside your communication platform. Ideally synchronized flawlessly with your Desktop, Web and (native) mobile clients. It all is there and it is fun to use, ready to be used instantly (as a service). Additionally Slack managed believably to diffuse concerns regarding administrators or managers to eavesdrop on the communication between employees by keeping the procedure for privacy transparent.

Also Slack makes a point in combining its technical excellence with a humorous approach towards its users and Administrators. Furthermore there is a rich Ecosystem of Plugins, Extensions and Modules to, for example notify specific teams in case of an event such as a Blog Post in the internal company Blog or an alarm from a monitored server.

Cons: Some of the features were more a distraction and we had to pick what to use and what to remove. This is not a real issue with the software itself but rather something that enforced us to discuss topics like - humorous chatbot comments ... a distraction or desireable? As with many Software products you use as a service, sometimes they break and all of a sudden all you can do is wait until it works again. It happened only once or twice since we used Slack so this is not really an issue. In General, it is hard to think about anything to complain about regarding Slack.

Overall: Slack was a real breakthrough for us in regards to communicating as a team and a company. We use it daily and intensely so. The team behind the software obviously is using it itself and has a keen eye on what would be a helpful feature and what a distracting nuisance. For me it seems as if someone who really has the same communication requirements as ourselves is developing a software to cover exactly these. We hold Slack in high regard and anyone I know who is using it agrees, Slack is THE Communication and Collaboration tool we were waiting for. Furthermore it keeps improving and growing and sensibly so.

Pros: Slack has helped my team communicate more effectively and work together more collaboratively than we were able to before. Channels are the best feature for our team. They help us keep our conversations segmented so that we can find information easily and share it with only those who need to know. Since I use Slack with internal team members and external collaborators, it also helps me keep communication with others in my organization who don't work directly with me but with whom I need to communicate on a regular basis.

Cons: The onboarding process is still a bit difficult. It's hard to explain what Slack is to others who aren't familiar with it, and the learning curve can be a bit steep, especially for those who are most comfortable communicating via email. I've had difficulty getting some external collaborators to use it because of that barrier.

Overall: Overall, I've been very happy with Slack. I have people who often work remotely, and being able to have a centralized, searchable space for conversation that can be delineated by topic is a lifesaver in a lot of situations. We are often working on multiple projects with multiple stakeholders, so keeping those conversations clear is essential. But what I like in particular about Slack is the integrations that make the space fun. There is a default random channel that is created, and being able to have a channel in Slack where my employees can post random gifs or talk about off-topic items has not only helped build rapport throughout the whole team, but as also made Slack become a more integrated part of our entire team structure. Employees can bring more of themselves to work through Slack, and that makes my team work better and more effectively.

Pros: I really like the way Slack enables team communication. I have used Slack in both paid/free versions.

I used the free version (limited storage for conversations and files) in a 40 people co-located team. It was very good for short interactions and immediate file sharing. We had a link with Jira, so we were always seeing issues being updated and such. Previously, we had Trello and it work very good too.

I currently use the paid version in a remote team and it's our day to day communication means. We have linked GitHub to have a "center monitor" for created issues, pull requests, etc. Also, all of the alerts, regarding website functionality/life are connected in real-time to Slack, so we never miss an alert.

It's very useful to have the paid version as it holds the whole conversation and file history. It's very easy to use the search function to find my own files or even things that were discussed in conversations.

Cons: After a while (or update, I'm not sure) using the free version, the storage of conversations and/or files didn't lasted much. So, if you had a conversation last week, forget about going back to that.

Also, in the free version it feels very much as if your files and conversations are held as hostages.

I think there are still some integrations that needed to be improved, for example, when I accidentally accepted to show previews of GitHub issues I couldn't find a way to turn it off (or an easy way, at least.)

Overall: I think Slack is very good for team communication, though not "the only answer". I say this because, for example, it isn't the most appropriate tool to handle team wide calls.

It's worth to pay for it if you need to access your history files and conversations.

Pros: Slack helps our team of 40+ people stay organized and on task. I'm not an early tech adopter, but I LOVE having my email inbox NOT inundated constantly with various subjects and to-dos. In fact, we never use email for our team, with the exception of occasional messages that come in from someone outside of our organization that we all need to discuss (and even then, copy and pasting it into Slack often yields better results and responses!). Slack has the level of organization (through both separate channels and also individual threads/discussions within each channel) that email lacks, with practically the ease of texting if you are using the phone app. Within the computer app, the separateness of the software from a web browser minimizes distractions while working within the app, although it does require switching back and forth between the two if additional info is needed.

Cons: Slack does have a significant learning curve, especially with all of the special functions that are possible within the app; our team uses very few of the special functions because they aren't immediately intuitive and we haven't taken the time to get trained on them. Channels can get cluttered quickly if threads are not utilize properly, and it can take time to scroll back through the channel to find posts (although there is a search function). Also, it's a small thing, but we use the emoji "reaction" function regularly to post Yes/No questions, vote for approval on proposals (Thumbs up!), etc., but Slack does not currently notify posters of emoji "reactions" to their posts; they just have to go to the app to see whether anyone has responded or not.

Overall: Despite the time it took to get accustomed to the software and the constant teaching we have to do for new members of our team on how to best use it, I'm so glad that we switched to Slack. It works for us because we have minimal use for emails and are frequently messaging about things that require quick responses from many people. I have only used it on a team of 40+ people for part-time community organizing, not a full-time job or project, but it has reduced so much stress and greatly increased our productivity and communication. Plus, we can have separate channels just for jokes or recipes, so it adds a fun element to our work without ONE MORE EMAIL in everyone's inbox.

Comments: Overall, wonderful company. I've been with them for 2 years. Incredible updates to this software in that time. It's so integrated into my company because I don't have a traditional office. My team is spread out all over the state.

Pros: You have everyone together in one place You can set up multiple projects or companies under one log in with different users set at different administrative statuses to limit access to different employee levels Real time follow up Keeps the team interactive which increases productivity and progress Navigating from one team or company or project to another is very easy using the desktop app Very productive when your team is not located all in the same physical office - that's its major benefit. The monthly cost of this software is a fraction of paying for office space. All the messages are archived so you can always go back and review anything you want or follow up on any outstanding issues. Immediate feedback from your team. Constantly getting the most updated info for your projects and/or teams.

Cons: If you don't download the desktop app and only use the website, it can be difficult switching between projects or companies or team You will need the app to ease the navigation of the software If you have a physical office that everyone goes to, then this will still be helpful as a follow up but you would really get the full potential of this software Sometimes it becomes a social platform that your employees get lost in talking about non-work topics and end up spending hours chatting. Personally, I think that if you have a physical office, you will need to make sure to set boundaries on usage and only use it as a follow up but again depending on your number of users, may not be worth the monthly. Also, if you have some users and/or employees who are not tech savvy or don't use messengers on a regular basis, this will be hard to intergrate that person. It only works when people are active on the software and use it as your main line of communication. If some users and mixing between emails and slack, then you will be missing out on a lot of communication and will result in some miscommunication

Pros: Slack is a communication tool for all employees in one place. I love how we are able to start a channel to talk about a specific project or chat to individual people. In my life of field i work in multiple different department from various different time zones but Slack unites all of us together. You are also able to integrate a lot of third party tools to help your conversations. I very much use the Gdoc integration and the conversation pinning functionality - I'd like to keep the more important up to date information on top of the chat thread.

You are also able to access Slack from majority of the devices, there is a nifty Desktop App, equally better mobile app and a web app all of them can be configured differently. For example, if you do not want a notification on your mobile but instead you want to follow the conversation on desktop - Boom, its possible and you can configure it all.

Cons: There are couple things Slack could improve. Firstly, Slack needs to allow their users to import table - if you are copy pasting an information from a table, Slack is not able to dissect that which is really a downer. The other being, connection issues, lately Slack has been having some connection issues whereby it is the only software in your system to not connect to the internet.

Overall: Overall, Slack is a communication king. It acts as a one tool for all and seamlessly allows multiple integrations with so many third party applications. All of its content are searchable, pinnable and configurable to your personal preference. Slack makes file sharing easy across all conversations and is available for across multi platform.

Pros: I love how easy Slack is to use. It's extremely user friendly with a familiar interface. If you ever used AIM (instant messenger) or iChat in the past, Slack will feel very similar.

I also love that we can drag and drop to share large files in Slack. When working in a fast environment where things like presentations or creative need to be reviewed around quickly, but are too large to email, Slack is a really handy tool.

Also, the ability to share code snippets without the formatting getting lost is huge while working with development teams. Excellent foresight by the Slack engineers to include this functionality.

Finally, Slack bot responses! I was able to set up responses for lost passwords and logins for our team, as well as basics like team member phone numbers, or birthdays, so we aren't digging through address books and instead we can just quickly ask Slack for help. It's really great.

Cons: One thing that's actually really frustrating is not having control over deleting conversations. As with any direct messaging app, there's an expectation of privacy between those two people. However, it's really unclear if upper management can ever access these direct messages. As such, I know a number of people who had tried to mass-delete threads (in the event mgmt could read them) but it wasn't possible in the free version of Slack (and I'm unsure if it's even available in the paid version).

There are third party apps to help delete comments, but it'll only do yours and not the entire thread. It would be helpful for employees to know exactly how private their direct messages are, and have the ability to delete content they want to.

Also, being able to have the slack bot responses work in direct messages, and not just open channels, would be nice. Being in a playful environment, different groups have added various, secret, slack bot responses, but most of our communication happens in direct messages and not in the open channels. As such we lose out of this fun functionality.

Overall: Overall I don't know how we would function without Slack. It is a key component of our company workflow and with all the integrations available with Slack, we're being more productive, seeing less in our inbox, and getting work done faster and efficiently. We will likely move up to the paid version soon, since there are additional function's we'd like to use (like accessing archived conversations and files). I would recommend Slack to everyone - I even use it personally in place of other messaging apps!

Pros: I owned a company that had quite a few people working for us that were overseas and communication was key. We started using slack and it greatly improved productivity, communication, and clarity. It was very simple to learn and use for everyone in the company. It is essentially a productivity social network for a business.

You can pin important announcements and topics to the top for everyone to see. Anybody can tag anybody or a group of people in the discussion. When you tag someone you know they will receive the message because they will get a notification they have been tagged. We set up multiple channels for all of the departments such as marketing, development, management etc. Having multiple channels is convenient for everyone so that they only see relevant information.

You can archive all of the channels or particular channels for your internal records. The search feature is nice if you ever need to go back to see what was said previous. Slack integrates to almost any other software as well. We had ours integrated to Dropbox and Trello. If you use any other mainstream software then there is a high likeliness that slack integrates with it.

The app for Slack works with IOS or Android. The app works flawlessly when we used it and it was very useful. I used the app almost more than I did the desktop client. Whenever someone tags you or pins something then you will get a notification on the app. You can also change app notification settings.

Cons: The only drawback I have found with Slack is the video chat feature. It may have improved since I last used this feature but it seems to have some bugs. It would drop calls or the quality would be poor. We ended up having to use Zoom or Google hangout for the video chat. However, it is convenient within the video chat you can screen share.

Pros: The user interface is really elegant and powerful. I particularly appreciate the 3 pane display that allows me to see which channel have updates so I can easily switch and the right pane to see content of a thread or search results without loosing my context.

I also really appreciate the possibility to add our own set of icons. In our case its particularly useful since our group discuss about methods that have their own icons.

The direct message module is very useful and clearly identified as separate elements so there are no risks to mix it with other conversations.

Sharing documents is quite easy and the preview helps a lot when you are searching for a specific document previously uploaded.

The search functionality works well and search results are clearly displayed.

Last but not least, the windows application is very useful and I appreciate to have a separate application instead of a browser tab dedicate to it.

Cons: Switching from a workspace to another one is always confusing for me. Never sure about how to use it correctly without loosing an update.

Seems to be a recent change, but search results are now displayed in a popup window, then you select one result and you are redirected to the thread and loose the list of results. It's quite disturbing for me and I still have to learn how to use it in a comfortable manner.

I'm also puzzled by the 'All thread' view where I'm always lost. You can scroll up and down and you never know exactly where you are. Maybe it's useful for other people but for me the best views are the Channels.

Overall: Thanks to this software, I keep connection with a network of international experts from everywhere on a passionate subject that we continue to build together, including rich conversations , sharing documents and setup workshops all around the world.

Pros: This is a good piece of software if you have multiple teams that need to communicate in real time. In our company, we have teams across different buildings communicate casually in the back-ground whilst work is on-going.

This is very handy if you have questions or tasks that need following up, as you are able to send notifications that are more visible than an email but not as intrusive as a face to face request.

This tool is particularly good for IT teams or employees who need to exchange files with real-time conversation, especially as 3rd parties can join channels as well. The ability to make private channels and have private conversations also allow for a degree of privacy where needed.

With there being both desktop and mobile versions of the app it is easy to take work on the go, great for if you remote work or are allowed agile working.

Lastly, there are some cool customisation features that allow a casual feel to the place, which is a must in any modern working environment.

Cons: The desktop/mobile versions of the app work fine. However, if you're in a VDI work setup and have to use the browser version you will probably experience some lag. You're machine will need some decent RAM to be able to cope when the chats get large and multiple conversations are occurring at once. When I say decent RAM, I mean not an ageing office computer.

If you have the FREE version you can expect older conversations to disappear, so if history and file space is important to you you'll need a paid version.

Overall: Easier and more casual communication between teams. Ability to take more issues at once without having to move around the building too much. Overall, I believe it improves efficiency and eases mental loads.

Pros: Slack is a tool that allows you to ditch e-mail in your work environment, probably for good. Since we implemented an internal Slack office environment (after about 5 minutes of setting it up) - We've found that our E-mail amount has plummeted to almost zero.

Day to day chats, tasks, discussions, updates everything is now usually carried out of Slack now, we have every employee using the Slack App (as well as the windows Desktop APP) and they both work brilliantly, allowing our staff to keep up to date when out of the office on the road.

Every time we've challenged Slack to fit into another area of our company structure, it's passed with flying colours, we've implemented a few simple bot's that track peoples work, (again not too difficult to set up if you're a programmer) - I cannot recommend it any higher, if your organisation isn't using Slack then you're definitely not as efficient as you could be.

We've since joined a few 'group' industry slacks which keep is contact with tens of thousands of people within our sector, we can ask for knowledge, advice, or simply post job adverts all through a simple chat program. It's definitely opened doors that we wouldn't have even known about before, as well as helped us get in touch with friends, old colleagues, and new potential hires. All by joining a relevant industry based Slack channel.

It has deep integration with most other software out there, (Trello, Google Docs, Calendars, etc) - It's amazing and highly recommended.

Cons: There really isn't much we don't like about Slack, it can become a bit of a distraction at times if you don't manage the alerts and notifications properly.

I guess on a personal level, it also makes it harder to disconnect from work when out of office hours as there's always a form of communication available. None of these criticisms really fall on Slack however, and more on our work culture and rules.

Overall: It's almost completely replaced Email within our business, it's amazing and handled nearly everything we have thrown at it so far. It helps us connect with multi-site colleagues and with our publishers.

Pros: Slack has totally innovated the way our team communicates and our productivity would not be the same without it.

Slack allows you to efficiently communicate with your team in a fun and enjoyable way. Unlike email, messages and files are easily searchable in one search box and slack also collects all of the attachments in your workspace together so they can be easily found.



Slack threads make it easy to organize discussions around certain topics and if the topic is important you can create a channel from the thread itself. You can also make these channels private if not everyone in the workspace should see the conversation.

Slack has incorporated really useful apps. I have taken advantage of the app to send polls to my team, and creating asana tasks right from a message. I also get a message from slack every day listing the events I have on my calendar for the day, and set up a way for students workers to clock-in right from slack. Recently slack has also integrated with Qualtrics, and you can have Qualtrics send slack message triggers which is awesome!

The slack app for ios is great. You can quickly answer co-workers on the go, and you can set your notifications to go on do not disturb during a certain time period each day if you do not want to receive push notifications out of work hours.

Cons: There really aren't many cons to slack although the app on the phone can be a bit buggy at times, but no real complaints and they seem to address any issues with a timely update.

Although slack has a multitude of apps, I do wish there were some apps they had. For instance, I would like the ability to create a google calendar event from a message or send a google calendar invite through slack. Although, they seem to be constantly innovating the platform, so hopefully this will be possible in the future.

Comments: Overall, Slack is definitely a tool you can vouch for!

Pros: After having worked in the IT sector for 3+ years now, I can safely say that Slack is one of the best channels for internal communication - primarily because the design is extremely balanced; it is not archaic nor is it designed to look too casual a chat platform. I will quickly walk you through the pros of the product based on my experience as well as the useful features of it. 1. With slack, you are assured of a good UI. I have used similar platforms for internal messaging like spark but there were quite dated in terms of how they looked and worked. Majority of times, the file always showed transfer error. Slack ensures sureshot file transfer 2. In addition to the point above, there is a very useful feature of "All Files" that helps you view all the files you have received so far. Great for record purposes, to double-check and re-download easily in case you have lost the file 3. You can set reminders to yourself - Absolutely amazing especially for those tiny tasks in between that I gotta finish but generally tend to forget because of daily duties 4. Customised channels - I can create multiple different channels for different categories of communication. Much like how we create "groups" in WhatsApp - That is how it works. It is especially good when you want to disseminate important information to a particular set of people 5. Apart from reminders - You have your personal chat page which works like a "diary" for me. So I can put my daily tasks, save links or even "test run" certain messages. It is a pretty useful feature! P.S. Not exactly a benefit but apart from a fun UI, it always opens up with a fun quote which is just nice to read overall!

Cons: 1. The application is too slow at times, to the extent that all other files hang. Tip: Once you have your workplace's account on Slack, just use the web version - It is not slow as the app is 2. The bottle-cap on the number of messages - I would like to use a communication tool safe in the knowledge that I can use it whenever I want to with no limits whatsoever. The upper limit of the number of messages that you can send deters me from sending quick messages to myself/others

Pros: My team uses Slack at work and I basically live in that app. It manages to solve a bunch of needs at once, from instant messaging, to video chat, to a team wiki, and much more. The open and closed channels (for public and private conversations) are a great way to cut down on emails. The ability to customize your notifications means you can control how often you want to be bugged about what is happening in each conversation, and the alert forwarding means you don't have every device you own ringing with every single message you get. The file sharing and rich search means that just about any in-progress document that is being collaborated upon can live in Slack. We love the Post feature that allows you to create Markup-friendly documents directly in Slack that can be referenced easily. We use them as a sort of knowledge management tool for new users to get caught up or existing users to reference important information. And perhaps my favorite feature is the vibrant development community that has created what feels like hundreds of different plugins and apps. Some of these connect with popular web tools like Google Drive (connecting it will alert you directly in Slack when a document you own has been edited or commented on), or apps designed specifically for Slack. These include everything from chat bots to polls, to much more.

Cons: While it's great that there is a version of Slack for just about every conceivable platform, like Windows, Mac, iOS, Android, etc., as well as a web version, the desktop apps are basically just web containers and don't feel as snappy at times as they could. And while most of my team is tech savvy, some of the tools are not particularly user-friendly for those who aren't comfortable with the things like slash-commands.

I've used Slack in my current company and at my last company and absolutely love it.

Pros: I love Slack because it's so ridiculously easy to use. It makes communicating with colleagues easy, *FAST* and fun. I work in tech and worked at an advertising agency previously and have used Slack at both companies.

The amount of times I'm asked to send a file or shoot someone info in a day is limitless and Slack prevents me from having to start dozens of email threads with formal messages like "Hi [NAME], Please find attached the [X] files you requested. Let me know if you need anything else!". Messages like that are no longer necessary with Slack, because I simply drag and drop the files to Slack direct message and BAM the task is off my plate.

Slack is also amazing for group communication. Since Slack messages send so quickly there's much less repetition than there is on email. It keeps things efficient and keeps us moving forward faster especially for tasks / topics that are urgent. If I email 15 people, odds are more than 1 person will respond and they may even respond at the same time as one another. Before I know it, I'll have a long email thread with jumbled messages because servers are slower and people aren't refreshing their emails to see if they've received a new email before sending theirs. Slack prevents this repetition and confusion by all group members being able to see a live thread that auto-populates.

Lastly, Slack is fun. You can send GIFs to your colleagues that are topical to the conversation or just totally random. Makes work better.

Cons: The only aspect I'd say I dislike is I feel like I'm not utilizing all of Slack's features, because I don't know what else to leverage beyond what I already do. Perhaps introducing tutorials or recommendations would be helpful so users know they're using Slack to its absolute highest potential. Other than that, in my 2+ years using the program I haven't experienced any issues.

Overall: Efficiency in time, clarity in communication, speediness in communication, entertainment in communication.

Pros: The company I work for used to use a group chat in a social media platform to try to communicate with our employees - we're small, and the number of employees wasn't too large for this, but we had quite a few different group chats, and they all bled into our personal lives. When I found #Slack, I immediately knew this was the answer to the ever-leeching work-life balance conundrum caused by having everyone at work affiliated in my social media account. Within a few weeks, we had our core chat channels set up in #Slack, and we even installed busybot and a couple other add-ins. We were customizing it and using it company-wide in no time at all. It's been a life saver. The channels keep different streams of communication open, and the best part is that it's FREE - as long as we don't want to search back through past 10,000 messages in our archive, that is. But the best part of THAT is that it's there to upgrade when we want to.

I actually have two jobs, and both of the companies I work for use #Slack - it's just that much better than the other options out there. We integrate our Google Calendars with it, and they show up in the channels we've chosen to filter them into so that employees can see the schedule for the next day.

Cons: The only thing that I feel is missing is the ability to copy an image and paste it directly into #Slack from the desktop. You have to download the file and then upload it, which is not a major problem, but most applications have this ability now, so I constantly try to do it, and then it doesn't work.

Overall: It helped my company reduce the spillage of work into everyone's personal social media. It's also a really great way to communicate with coworkers and get things done. We've almost eliminated internal emails!

Pros: Slack was built with a very powerful software architecture in mind, yet so many individuals can use it because of its friendly user-interface. The design is very fun, playful and gives you the powerful functionality that you never thought existed. For how many use cases there are in Slack, they make the user experience very streamlined and easy to pick up. In addition, you can sync a lot of the other programs that you use with their integration features.

My favorite is the ability to keep up with internal conversations based on the topic. I personally dislike being in group chats where the conversation isn't relevant to me. It can be of annoyance receiving notifications that don't pertain to your role and you have to check and delete at a later time. With Slack, their channels can be very specific and allow you to pick and choose which ones you want to join.

Cons: The biggest takeaway is if it's not used right within an organization, it can be a productivity killer. Slack connects to both your mobile device and your laptop so if you do not manage you notifications right, it can be virtually impossible to escape the conversations that are going on. Saying this, our team implements certain hours of the day where ALL phone and laptop notifications are off. Slack makes it possible to do this by changing your modes of availability and/or snoozing the notifcations for certain periods of time. As long as you limit the amount of channels to the ones that require you rattention and don't spend your whole day falling in the trap of checking your notifications all the time, it can be an awesome tool for communication.

Pros: When working in teams of many sizes, Slack makes chat fun, efficient and non-obstrusive.

Slack is modelled on IRC, with users joining a "workspace" comprised of any number of themed channels. Users can set their notification preferences for each channel, which makes it possible to control the volume of notifications.

While some channels are meant to be used by everyone (#general, #random), it's very easy to create new channels for specific projects or discussions. I love the fact that all workspaces allow by default a "random" channel, encouraging non-work related discussion.

The flexibility afforded by this organization makes Slack a great fit for any kind of project sizes, but also other communities.

Finally, Slack supports powerful formatting (bold, italics, code snippets, quotes all using the intuitive Markdown syntax). Emoji and GIF support makes it even more fun. Emoji reactions are an expressive and fun way to respond to messages quickly, avoiding time wasted on picking phrasing (and spamming others with basic responses).

Cons: In settings where the free plan is not sufficient (e.g. large number of users), the "pro" options feel quite expensive.

While clients are extremely well designed on all platforms, handling multiple Slack Workspaces is still a bit of a hassle. Notifications arrive for all workspaces, but one needs to explicitly switch between workspaces to see messages. A unified view of all new messages across workspaces would be amazing.

The lack of a single account means that any preference set into one client (e.g. on desktop) will generally not carry over to another (e.g. mobile).

In terms of administration, I wish that we could set the default notification settings per channel, instead of requiring each user to go and tweak them manually.

Pros: Slack simply has everything I've ever wanted it to have. Everyone knows about it, everyone knows how to use it, and nobody ever has an issue. I am part of a handful of communities there where I enjoy collaborating with people across the world, but I also use it internally for work. I have used it at my past 3 companies, and I just honestly don't know how a company would operate without it these days.

There are so many integrations, so many ways to share and collaborate, and it's accessible everywhere making it very reliable.

We just starting testing out Hangouts Chat, which has the only advantage of being more integrated into Google, but I don't know how it could possibly unseat Slack. There just isn't a real problem with Slack in anything that you do, so while Google may make a comparable piece of software, I doubt they can battle the network effect that Slack already has.

Cons: The thing I like least about this software is probably the culture it creates in that every is available everywhere all the time. While Slack addresses this with the ability to Snooze notifications, chat communications just makes you feel like you can have access to anyone and their work/information whenever you need it (and let's be honest, you always need it now).

It's better for communications, but as always with something like this it's a double edged sword. The more connected you are, the more you are chained to work at all times. Of course it's the choice of the user to avoid that, but if it evolves culturally within a business because it's just so easy, then it's hard to avoid.

Overall: It helps me communicate with colleagues across the world and lets me be more flexible geographically.

Slack is always on their game.

Pros: Uptime: There have been so few service interruptions in the last year. I can only remember one service interruption that has affected us where general functionality was unavailable for about 45 mins. Obviously 100% uptime is preferable with any software, but I'll accept 99.999%.

Fun: Slack feels fun to use and I'm not ashamed to say that otherwise boring conversations are elevated in their level of fun because of Slack use. Slack, for me, really evokes some of the early days of IRC, YIM/AIM use with the plethora of available emojis, shorthand, gifs, and so forth.

Flexibility: Need a new channel to discuss the latest project? It takes 20 seconds to create. Need to integrate with X service to fill Y business need? No problem. Need to set up a bot to help keep track of Z issues or to spin up a new QA database series? It can do that.

Navigation: Navigation takes about a week to learn, but becomes such a seamless part of your experience with Slack, especially with keyboard shortcuts. Channel hopping is easy, DM hopping is easy, thread creation is easy.

Cons: Cry Wolf Effect: The larger your organization, or the chattier your employees/co-workers, the less productive slack can become. Sometimes you really need to be in a channel because of its important messages, but if your teammates are blowing it up with cat gifs it becomes white noise. This sets up the "Cry Wolf Effect" whereby posting abuse means you are never sure if the channels that are important ever have anything important going on in them. So, unless you constantly check them it becomes fatiguing really quickly. Yes, one simple solution is to set up a dumpster channel for the white noise, but its really easy for that to leak into important business channels unless everyone agrees to a standardized code of posting behavior and rules.

Pros: I've been using Slack for quite a while now. Using it with a team of 15 people. I also have used facebook workplace and Chatwork, just to see what else there is but always came back here. It's easy to use: I use Slack in Japan with Japanese coworkers, some of them don't speak English. Now Slack is available in Japanese, but for the last 3 years when it wasn't, UI was still simple enough and never a problem even though Slack was only in English. isn't this a compliment? haha With 3 years I did experience some bugs (partly my fault cause my Phone was a bit outdated), but customer service was always there to help and they were super fast & updated the app to fix it. Free plan available. Everyone on our team is always online so it's very easy to chat: you could argue that this is the company culture or team's responsibility but if the UI is difficult noone goes online and everyone starts useing other ways to communicate (experienced this with Chatwork)

Cons: Sometimes app updating on Windows 10 was funny: inconsistent icon designs on the Tab Bar. But maybe that is Windows 10s fault but never had this happen with any other app If you are on the free plan, you need to store important conversations somewhere else because old messages disappear, but we just use Slack for communication + sharing, and Google Drive for storing important data. Important data should be stored better than just in a feed anyway. Problem Solved. I think people tend to think less what they write on Slack compared to email. So you sometimes end up spending more time talking about something on chat and wasting 2 people's time, whereas on email one person thinks until it's worth sharing, then sends the email, so less time consuming in total. but in the end, it's good to keep conversation running so maybe not too big of a contra.

Pros: We're a nonprofit organization with employees on three different continents across five time zones, and Slack makes it feel like we're all in the room together. The problem with email and other instant messaging applications is that they're not very inclusive; if you leave someone off of an email chain by mistake, they're completely out of the loop. With Slack, on the other hand, you can post general updates that the whole team is immediately aware of. You also have a central archive of all your messages and documents and discussions, so your institutional memory doesn't walk away with various employees as they come and go from your organization. The channels allow us to make sure everyone on the admin team gets every admin update, everyone on the fundraising team gets every fundraising update, etc. We even add outside vendors and visitors to our project site to Slack as need be, because it's simply the best way to talk to any of us.

Cons: It's hard to think of downsides of Slack. I guess I wish it loaded faster when we're on a poor internet connection in a third world country, but that's only a problem occasionally. The only other thing I can think of is that messages can sometimes get lost in a stream of chatter, the way Facebook updates can get buried at the bottom of your newsfeed under less important posts. But I view that as a downside to any form of communication.

Overall: Our team's communication has benefitted immensely from this software. We're not only able to communicate with one another much faster (rather than waiting days for an answer to an email, you can get an instantaneous reply to your question in Slack), but we're also able to keep in touch with each other with a much higher level of detail. We're aware of more of the day to day occurrences in each of our spheres, and feel like we have a much better sense of what each program area is up to. This is true even for simple logistics. At our nonprofit project site in Nepal, we used to have simple communication issues with people not getting the message that dinner was moved an hour later or a trip to the river had been planned. Now, one simple Slack message lets everyone know.

Pros: There are so many reasons that Slack is amazing. Here are a few:

1) Easy, Efficient Messaging - Prior to our switch to Slack, email inboxes would be filled with short replies to internal communications that would have been better handled with a quick conversation. The Instant Messaging feel of Slack has allowed us to virtually eliminate all internal emails, keeping our inboxes client-focused and uncluttered.

2) Clear project communication - As an agency, we have a ton of diverse projects. Slack channels allow us to address only the relevant team with the right information at the right time, making it simple to keep a continual history of project communication and an easy vehicle for getting to the right information fast.

3) Amazing Client Collaboration - We LOVE the ability to invite our clients into a single channel for project communication. It's mostly an advantage for clients who already use Slack on a daily basis, but it makes all the difference and helps them feel as though we're always online for them.

Cons: Despite how great Slack is, there are a couple of road bumps to the experience:

1) Channels can get overwhelming, especially if you have lots of clients and internal teams. It would be so nice to have a foldered-system or some other way of grouping channels in order to not have to scroll to find them.

2) The icons at the top of the channels can be misleading and unclear. It's too easy to accidentally add a single-channel user to your entire company's Slack space without realizing it, and that presents an unintended area for exposure and potential liabilities.

Overall: Slack literally revolutionized our workflow and internal communications process. The time and share of mind saved from separating internal from external communication is unreal, and the benefits come incredibly fast. Within a week of the shift, everyone from the executive team down experienced a collective sigh of relief, and looking back on old processes now, one might be excused for wondering how anyone could have used email as a form of internal communication.

Pros: Slack is a flawless software for staying up to date with your teams or communities. There are so many features that I could write an essay about but I like the 'bot' functionality the most. You can set up a wide variety of different bots to help with the automation and logistics of any number of tasks from as simple as calendar scheduling to building out spreadsheets for data/assets exchanged in slack. The sky's the limit!

You can even integrate with almost any other app or software that you use for a seamless online experience.

I also really love the interface and UI/UX. Very simple to understand and navigate if you've never used Slack before.

Cons: There's very little to say against Slack but what I like least is the difficulty of tracking messages if you have a very large team or community. If there are say, over 1000 people in a channel, it can be very easy to lose track of the conversation or to become overwhelmed by the number of messages that build up.

Overall: I work remotely almost 100% of the time and collaboration is very important to me. Slack helps me to ensure I have frequent and high-quality communication with my teammates. It's essentially solved our problem of miscommunication by using channels and setting ground rules for how we use to the software to communicate.

Slack is a facilitator for our company culture and ensuring we are connected, in tune, and aware.

I am also part of many online communities which use slack to stay connected and involved. This is really great for having collective discussions around a myriad of topics, and also great for having more intimate one-to-ones.

Slack is simply awesome, we use it pretty extensively in our organization

Pros: 1) Code snippets for various code languages (Slack does this the best).

2) Reply to a particular message and start a new thread.

3) Posts.

4) Private / public channels .

5) Slack calling and screen sharing.

6) Web hooks / slack bots (We use this for monitoring our system and health checks.

7) Address individual users using the @ or @channel or @here.

8) Pinning certain uploaded files to a channel or conversation.

9) File uploads itself are pretty smart themselves.

10) Group conversations.

11) Seamless connectivity from your phone.

12) Well designed status module which allows you to set customizable status messages .

13) Ability to snooze notifications.

14) Ability to be notified about channels, whenever someone mentions you with an @, etc

15) If you have not used /gif in slack, you not really used slack.

16) Video rendering within conversations is pretty neat.

and the list goes on....

Cons: 1) Screen sharing module could be improved

2) Pencil / marker icon only available to viewers and not the presenter

3) When network connectivity is lost during screen sharing or calls, the reconnect feature doesn't seem to work really efficiently.

Overall: I use this software everyday and it helps me work very efficiently.

Its a one stop shop for keeping me in touch with my colleagues when we work from home, maintain group conversations, use channels (public or private), upload and share files, have important conversations, and monitor our systems via the use of slack bots.

I would highly recommend this product without a doubt.

Overall excellent product in every way, shape, and form!

Pros: Slack is extremely easy to use, set up, and navigate. My company has been a user of Slack since their inception and I've seen lots of features that've been added in that time. They just seem to get it. They know what people want and are always striving to provide it.

You want calling? Boom... got it. You want gifs? Oh boy, do you get some gifs! You want to make your own custom emojis for those inside jokes or common sayings around work? You got it!

I could go on and on, but overall Slack is an amazing tool that's helped communication immensely in our company. We're very remote friendly, so having the ability to stay in communication with my colleagues around the world is key, and Slack makes that happen seamlessly. They also have many features that allow you to set your own work/life balance and stick to it with ease.

It's become such an intragal part of our company's communication that I couldn't imagine life without Slack.

Cons: If you get the free version of Slack, you get many of the features that the paid version gets, but one of the biggest drawbacks is you're very limited to how many historic messages you can see. If you belong to a group who's on the free plan, it can be tough since you're unable to see messages that you may have missed.

Another downside is that the search functionality is a little weak. It's not terrible, but it could be greatly improved as it's sometimes really tough to find what you're looking for.

Makes it feel like my coworkers overseas are just a desk away!

Pros: It is hard to narrow down to one thing I like the most, so I will give something general that encapsulates it all- Slacks customization is robust and intutive to my day to day work. It answers needs I have if I need to communicate with a small group, a private group, a couple people, an individual including phone or video. It's integrations are excellent to sync up with many other tools I use, most noteably Google drive, which operates as a notification system if I get a note on a document, I can see it right in slack.

I work in a global company with 5 offices in 4 different countries, so staying connected is essential. Slack really is the glue that holds us together.

Cons: For certain accounts, the more users and use you put into Slack, the quicker the history erases. It is probably a good thing for us to never save important notes within, but would be nice if I miss something it doesn't erase quickly. I understand that we get a longer history for higher paying tiers, so the functionality and solution of what I like "least" in the software is available.

Overall: The increased efficency and productivity in my day to day work has sky rocketed with Slack. We can segment groups based on specific projects and groups so we ensure we are only including those who need to be involved and not having wasted meetings to discuss things that can be accomplished on a segmented Slack channel.

Working in a global company, I do not get to have regular f2f interaction with my colleagues from other offices, so Slack is the main way to communicate and get to know others.

Pros: I don't remember how my team communicated before Slack. It has been a central way to communicate at work. It especially keeps my coworkers connected as some are remote. It cuts down on our emails and makes communication easy. Better yet, the free version we are currently on has a lot of functionality without upgrading to a paid plan. There are also a lot of apps and integrations that can be added to automate processes - e.g., we can automate the 'time off' process. You can even integrate project management tools to improve communication amongst the team.

Cons: There are a lot of notifications I receive that are not always relevant to my role at work in the team threads that are created which can become distracting, however I have learned to use the "/" sign in channels to mute them. I also find sometimes co-workers don't know how to use some of the features. For example, I often get tagged in direct channels, but don't end up seeing the messages because I am not in that thread. I have missed some action items because of it. I find too that messages sent with a lot of instructions/processes might be better off for email. If you are on the free version of Slack, it is more difficult to get back to items sent in the past because there is a message limitation - you won't be able to access your old messages if your team is passing the 10k message limit.

Overall: When Slack was down the one day, my co-workers reacted. It has become such a central way of communicating at work and everyone relies on it.

Pros: Slack is easy to use and has great built in functions for notifications and add-ins for automated posts. It has been helpful to get multiple departments talking at times and keep each department informed while not in the same location. The ability to upload files makes it easy to share ideas.

Slack can take a while to set up if you want multiple channels but once started, it is easy to keep projects or topics going in the different channels. Using the channels are intuitive and easy. Members can be added or join on their own, if allowed.

You can invite a customer to specific channel where the whole team can see their vision or wants but keep the other chats behind the scenes.

It's a very versatile chat option that could replace e-mails. The amount of built in functions and then add-ins for automation make this great for any business.

Cons: My biggest complaint is that Slack is too available. We're expected to know what's going on with projects both at work and at home. Having it installed on phone and work computer, it's always there.

Sometimes the channels will not clear unread messages on mobile even after reading them.

Overall: This software has really helped communication at our company. It allows users to discuss ideas with personnel around the world. Our department is is physically located somewhere different from the rest of the company so Slack has helped us remain informed and connected with the rest of the company. Less formal than e-mails but more informative.

Pros: We are a startup team of 4 people that work remotely and we've been using Slack for about 4 years now. It has been the go-to tool for team communication. Every conversation is saved and you can search for information that was discussed months back very easily.

Slack can be linked to different platforms and services like Dropbox, Gdrive, etc. We use it with Asana to keep track of our daily tasks. We have our daily standups via Slack's video/audio call feature which works really well and the screen share option has a very helpful tool that lets you draw (highlight) anything on the screen that is shared.

The Mac desktop application works very well, it's very responsive and very fast. The same thing can be said about the iOS app for the iPhone and iPad. Notifications can be customized very well and this makes reaching anyone on your team very easy.

The team behind Slack is very involved and pushes regular updates and fixes.

Cons: Coming from a non-technical background, it's a bit harder to wrap your head around it the first time around. It was easier for me to have developers around that got the hang of it faster and helped me out when I was in a pinch. Worth mentioning, that the above happened a few years ago and probably things changed a lot since then.

There's nothing else that comes to mind, as everything just works.

Overall: Best overall tool for communication and collaboration for any team size, from startups to corporate teams.

Pros: I love it that I can drag and drop files, images and videos into slack to share with my colleagues while we discuss about work . Unlike WhatsApp messaging, the software also has a snooze button which prevents folks for messaging you when it's time to rest at night. In addition, slack allows free integration with many other tools out there. Although I'm not a software developer, my colleagues who are talk about how easy it is in the backend for integration. Working at my previous company, my previous company utilizes slack to alert our customers that their order has arrived.

Cons: What I don't like about slack is that my chat groups are largely disorganized. Because I am in so many different chat groups, it's hard to remember the purpose of each one and where my messages are at for each channel. Also, I get 50+ messages in a chat group which doesn't pertain to me at all. I have to scroll through all 50+ of them. Another thing that is annoying is that we don't know if something that was communicated via slack time sensitive or not. It would be great if slack has button for that where we can signal that something is important and we have to attend to it urgently. Last but not least, slack doesn't integrate with my emails. Hence, I have to still check my emails on top of checking my notifications.

Overall: My overall experience with slack has been positive. My company used slack for internal and external purposes. My manager used slack to communicate to us when he's making sales and can't be in the office. He sends all his files via slack. We also use slack externally to send notifications to our clients when their order has arrived or when they have issues with their order.

Pros: What I like most about Slack is that it is a secondary or support tool that adapts to any environment. For example I am a computer engineer and this is a very popular tool among software developers because it allows you to take everything in order with the development of any project and have development teams no matter if they are physically with you. We know that the digital era has arrived and that is why it is very important to leverage these applications, which allow us to be always connected, as long as we have an Internet connection.

Not only have I used Slack for the environment of my area, but also for a business that works with network marketing. Slack allows you to order elegantly everything that has to do with my business, people, entire organizations, events, documents, etc. It is an excellent tool if you know how to use it.

Other things that I like about this application is that you can link it with other applications outside this one. For example Trello, Google Calendar, Giphy, Blue Jean, Zoom Cloud Meetings, Google Drive, Twitter, among many others.

Cons: As any application; It has a free version and a paid version. But regardless of that one of the cons for many people who are not used to these technologies, because they are digital migrants, it could be that they feel overwhelmed by the amount of features that you have once you are inside Slack.

Overall: I recommend 100% Slack to any colleague or person who is in a business model like mine. Imagine having more than 1,000 people in one place. Well what you can not achieve with WhatsApp, with Slack if you can.

Pros: Slack is an excellent unified communication tool that can really help streamline work processes for everyone from just two-person teams to even group collaborations between experts that are situated in different continents. Real-time communication and file-sharing allows our people to find faster resolutions and increases productivity so much that the need for exchanging emails back and forth or the possibility of ending up playing phone tag with someone has been reduced significantly because of this.

I appreciate the fact that you can install a separate application for this instead of needing to open it in a browser all the time. Aside from not having to look for that specific window you had it open in, it also allows any new messages to be more visible.

The user interface is very intuitive and easy to navigate. It doesn't take too long for anyone who's never used the app before to figure out their way around it. Searching for specific conversations and messages is also very convenient and accurate without sacrificing the context of the conversation.

Cons: As with any communication tool like Skype or Whatsapp, it can easily become a distraction especially when the notifications and alerts for groups/channels dedicated to office chit chat and socialization keep popping up now and again. So proper management of these groups is necessary at the onset to avoid this scenario.

Pros: The seamless experience between the computer app and the mobile app is perfect. You really don't loose any features or funcationality from one to another which is rare to find. I actually enjoy using Slack and wish it was my only form of digital communcation. They strike a great balance of "fun" and professional. Some software now tries to be too "fun" and "cute" and it just gets annoying. Slack is where work happens and things get moving

Cons: If you get team members who post too much junk on Slack it can get overwhelming. Sometimes getting through all the useless gifs and back and forth can take up some time but that can be fixed with some proper "Slack training" for the team. Probably my biggest con is that it can be really easy to forget about a message. If you're not good at setting a reminder or marking a message as unread to come back to, it's very easy to look at a message and then move on without taking action on something you needed to. With email, you can just keep the message in your inbox till you are finished with it.

Overall: There are few tools that I won't work without and Slack is at the top of the list. As soon as I started using it I rolled it out to all of my teams at my last company. When I was looking for a new job I actually asked them if they used Slack internally for their communication. Luckily Slack has taken off like a fire and it is rare to find someone who doesn't use it. I recommend it to every team I work with. I even used it for my team projects during school and it was fantastic.

Pros: Slack is a great software for:

- Communication- it has a good system for push notifications on the phone and the desktop app. It also allows for replies, or using an emoji as a response, which can also serve as a "Voting" feature when requesting a certain emoji as "yes" and another one as "no."

- Searching for information- The search feature is great, it works much better than imessage when trying to search for past messages or files.

- File sharing and integration with other software- It integrates easily with Drive and with Asana. Files can be shared through either of those or uploaded straight to slack.

Cons: - The file limit on Asana can really hinder its use, this can be overcome by linking through Drive, but downloading straight from Slack is much easier, however, if you are reaching your storage limit, you must go and delete past files.

- If you have multiple slacks, you have to sign into them through the app to get push notifications for that slack account. So you will only get notifications from one and not multiple. This is not the case for the phone app. Switching accounts is easier on the phone app than the desktop app.

Overall: I love working on Slack, it is a great communication software. It does not do much for tasking or keeping track of projects, but it is great for announcements, collaboration, and communication for teams. I highly recommend it for any work teams that need to communicate virtually or that do not always work in the same space.

Pros: * The best feature about slack is its channel and the direct messages user experience, very friendly and kind of easy to play around even when start using initially.

* Integration of apps feature is really great, where once you link the respective apps everything will be present here all at one place. Making life simpler

* Slack "Search" should definitely be highlighted here.Filter options search is very specific like conversations only with certain user, only in a certain channel, or any of several other filters .

* Slack in-built Call and File sharing/Code snippet is something which is great and used mostly everyday and works like charm.

* "Slack" be it Web/Android/Mac/IOS or even Linux. They have their apps available making it more of a reason to use and not to think about any restriction. Can use anywhere and everywhere

* Switching workspace is another killer feature that Slack has, allowing user to switch without being logout from one.

Cons: * It's slower sync on its startup makes it bit disappointed here. It's because It fetches all the data at once on load, so more the data higher the time it takes.

* Mobile push notification shows only top two items even if I keep receiving messages It still shows top two at the push making you to open the app to read all.

* Mac app Icon notification always shows the red dot even after clearing unread notifications,That makes you to miss seeing when you actually have one.

Overall: Team collaboration become much easier and simpler because of its features.

Pros: Slack offers a powerful chat system that was successful in removing the costly, inefficient back-and-forth email conversations in our organization, instead replacing them with fast, straight-forward chats within channels. Slack works seemlessly across desktop, web, and mobile app. Slack is the primary way we communicate in our enterprise, reducing internal emails to only a handful a week. It's also really handy for sharing quick screenshots or reference images.

Cons: The biggest problem with slack is remembering and/or finding the last few channels you've been communicating in. Here's the scenario: Someone asks a question in a channel, which makes it bold in your channel list. You click on a channel and respond to it, then move to a different channel. Interested in revisiting that last thread for some reason? Good luck finding it! We have about 25 frequently used channels/direct message channels so it's practically impossible to remember where that last communication was happening. The search functionality is okay, but i'd say we only find what we're looking for about 50% of the time.

Overall: Slack is essential to our business and makes group communication fast, straight-forward, and even fun. It's great for culture because it allows people to participate in group conversations without feeling like they are cluttering inboxes. Financially, it feels like it should be about half the cost, but we haven't found a viable alternative yet so we continue to stick with it.

Pros: This is a very good messaging software. You have the ability to use it via a browser or a client download on your computer and/or use it via an app download. The platform is truly agnostic. My firm uses the Google suite and we have had issues with our Apple users in some instances when they have attempted to use G-Chat on an Ipad Pro, most likely because of the restrictions between Google/Apple.

Cons: Overall, the software itself is really just an updated version of the old AOL Instant Messenger. Like AOL IM in its latter days, you could sign in via a client or in a browser as well as on some early smartphones. The real problem with Slack is that its IPO is coming up. As the firm is not profitable, and as this is their own business line, they will have to push more users to a paid subscription. Many of the features are already limited as they are pushing toward a paid tier - this will only accelerate over the next few quarters. I can not see paying for what is essentially a simple service dating to the dial-up days of the web. I am looking at expanding our use of G-Chat or Microsoft Teams as both companies have multiple business lines which are not dependent on "milking" this simple chat app. The amount of advertising I have seen for Slack has accelerated my move from the platform - when the VC money stops...

Overall: No real business problems are being solved. As a user of the Google Suite, which has a basic built in chat app, I now have another system to log into and check, so it may actually be creating more of a problem than a solution. If I had to press, the one thing it is good for is quickly chatting via a phone with international personnel (e.g. text message) as WhatsApp has lost trust since its extremely high priced acquisition by Facebook, who will have to begin monetization.

Pros: I like the way the software organizes "work spaces" which is 1 step higher than competing software like HipChat. Integrations are easy to install if you have admin, and the free platform is more than adequate for teams that don't require logging messages. Overall, it's a refreshed version of HipChat that is slightly less business centric and slightly more youthful and fun.

Cons: There's a trade off for being more youthful and fun when it comes to integrations, and there's no Suite that Slack is currently a part of similarly to HipChat which is part of the Atlassian Suite. This will likely change in the immediate future, and if you are strongly dependent on Slack there is no certainty it won't be bought by Atlassian just to be shelved. This uncertainty makes it a less worthy commercial application and creates a scenario that purchasing can't get behind for valuable multi-year discounted licensing agreements.

Overall: Under Private Equity we were looking to save money anywhere we were able to. Due to this, we dumped Atlassian's HipChat app and moved to onboard the free Slack option. Slack was adequate, but created greater tooling disparity and a wider range of 3rd party apps. The look and feel of Slack was very modern and capable, yet it lacked the polish of a commercial grade tool and had no accompanying suite for a bigger value add.

My final advice would be to give Slack a trial if you don't have a platform that is already part of a suite, but if you are looking to replace a suite-centric tool such as HipChat or Teams with this tool keep in mind that you will have a disparate tool to support outside of your existing suites. Great tool, lots of potential, needs a bit more professionalizing.

Pros: I used this when working with a team of around 50. Slack makes it extremely easy to communicate within teams - this includes with team-wide announcements, within smaller groups of the team, and with individuals in general. All you had to do was click on the correct channel, then type your message.

Notifications were also extremely flexible. You could get notifications for specific phrases or mute channels that you were a part of but didn't want to necessarily look at. Things like @channel were also useful to notify the entire team.

App integration was also amazing within Slack. It made sharing Google Drive or tasks with something like Asana significantly easier, and increased overall productivity.

The interface, for the most part, is easy to use. Admins can also customize workspaces a decent amount, like making custom emotes.

Available on many devices, making it easily accessible.

Cons: I have barely any complaints about Slack - only really that there was a bit of a learning curve, especially with the etiquette of how to communicate through the app. This includes when to use @channel, when to address everyone in the channel or just a specific person, and that's about it. Slack has been an overwhelmingly positive experience for me, as long as people didn't fully disable notifications.

Overall: I was using Slack for communication within the whole organization as well as smaller, more focused teams. Slack made it easy to share files that we could all see and edit and just made it easier to switch communication between different channels, rather than going to different group chats like you would have to on something like Messenger or iMessage. Something Slack improved upon over Messenger or iMessage was most people could easily create a Slack, as opposed to iMessage or Messenger where you need actual accounts (some people are opposed to using Facebook). Communication across teams is also easier, as you can just join a channel instead of asking to be added to it and then waiting for someone to add you.

Booming, new way of team communication with a few annoyances

Comments: If you're like me, you've probably heard all about Slack from different friends and businesses when it comes to how awesome it is with internal team communication. I'll admit that this is the reason why I first gave it a shot and while there are still a few bugs that I'll dive deeper into later, the platform is pretty cool and does a good job at helping you segment the different forms of communication you and your team has. Defining team communication channels is just one thing though. Slack integrates with a host of other business applications, making it more customizeable, helping your team be more efficient with their time and communication. Overall, it's not perfect but with help from their customer support and development team, it's getting there.

Pros: -Simple user interface similar to other, more established team communication applications like Skype. Also allows for more customization in channels and notifications. -Powerful and intuitive tools like search channels tool and file uploading and preview tool make it easy for you to find what you're looking for and see it easily without a full download. -Has a growing list of integrations with other business applications so that you can type a specific command into Slack and perform a task or action in the other, integrated area of your business. Makes it easy when you have items that you normally talk about in your team communications that then need to have some sort of follow-up or other process in another application. -Customer service is attentive. If you're having an issue or wish there was a specific feature, you can easily open a ticket with them and they will do their best to help you out or pass on your thoughts.

Cons: -Between the Mac app and the PC app, Slack differs greatly, with Macs seeing the cooler functionality and overall better stuff earlier than PC's. This is something that Slack seems to be working on but it's still an annoyance. An example of this would be the ways in which you can be notified of a conversation by the Windows app. You can only see if you have a pending conversation by looking at a tiny ball in the bottom of your windows icon set instead of seeing a giant ball on your larger windows icon pinned to your taskbar like you can with a Mac.

Pros: It is very easy to set-up and use. Very clear and flexible setting options. Beautiful UI / UX, easy to use and install. Very helpful for sharing information in teams or organizations. Very convenient, that there are not only private conversations, but also public and private channels. We use Public channels for info sharing and announcements, private channels to collaborate within different business processes. I used to use Slack also in different IT Software Development teams - it is a must if you need good communication between your team members. Plus Slack has a lot of integration options, you can connect you Jira for example or other services to share the information. 100% Best communication tool for teams so far! It is totally free unless you need such things as infinite history of chats, file sharing etc. And it has a cross-device support - perfectly working on my PC, WEB and on mobile.

Cons: There is no relay any bad UI / UX thing in Slack. Technically it is perfect! Of-course we all want it all to be free completely :) But for free you get nice and working tool. You only start to pay when you want your history to be capt forever and you want to share files in Slack. But if you use Slack for Instant information sharing, as it is designed for, you don not need your history forever.

Overall: Perfect information sharing and team collaboration tool

Pros: The Slackbot feature has saved me many times reminding me when my next meeting is coming up, sending me reminders for tasks I would otherwise forget and even holding others accountable when I have assigned them a task.

Being able to send messages to just the people who need to see them, and being able to search through our history has saved time (and sanity) spent reiterating the same processes. It has also cut down on the number of emails in everyone's inbox, making it easy to make announcements to the whole team. I can't tell you how nice it is to not have to ask 30 different people "did you check your email?" especially working in such a fast paced environment. It allows us to communicate changes and announcements on the fly as they happen in real time.

The features are robust enough that we have created entire systems revolving around the use of Slack. And it integrates with other platforms we use easily and seamlessly.

The app keeps everyone in the loop regardless of them being on site and the sleep function can be used when you need a break from the influx.

Cons: Mostly, my biggest problems are user related so I wish there were more options for training teams on best use. It can get overwhelming fast as there are a lot of features, so sometimes it can be hard to know where to start, especially when you're first starting out.

The sign-in process has never been perfectly smooth for us.

Overall: We love Slack! It has taken our fast-paced team and made them even more productive and efficient.

Pros: - Allows you to chat with persons.

- Allows you to create channels which helps to organize conversations for specific subjects.

- Allows you to start threads on a single message, that helps to not spam all the channel if you are talking

of a specific thing on the channel.

- Allows you to make calls, that helps because you don't need to open other app to do this.

- It has slackbot, it helps to organize things depending on the use you give it, also you can tell him to remind things to you or your team.

- It allows you to format the text on your message to help other people to understand what you mean in a easy way.

- The desktop app allows you to have multiple work spaces at hand.

- Allows you to integrate the app with others like bitbucket or teamcity, so you can see all the commits made on bitbucket, or the builds generated with teamcity.

- You can mention people so you know at least a notification will be sent to them.

- It has a mobile app so you can chat from your phone

Cons: - Sometimes to change between work spaces it is a little bit slow.

Overall: I normally use slack in my work, I'm a software developer and my team and I work remotely, so slack is a great tool to keep a fluent communication between the team members, also it helps to keep track of the development when you integrate it with another apps like team city or bitbucket. So in general the use of this app helps to improve the team work.

Pros: Slack has many many integrations, i.e. Dropbox, Gif's for the keyboard, trello, twitter, giphy, jira, GitHub...

You can easily create threats on messages and conversations, and differenciated channels according to a specific subject

It is also really easy to install and use with a very intuitive gui.

It is also very important to mention the amount of integrations that Slack offers, becoming some sort of octopus of business communications, this is just another key of Slack's success between its competitors (like old reliable skype).

Inside a long conversation between your colleagues it is very likely to get documents and files lost inside, fortunately slack offers a very powerful search tool that you might find handy to solve those kind of issues.

There is also a nice and well made App for mobile devices you may download easily from the respective stores.

Cons: When you get in love with a software or platform, it's always awful to let it go... and for many, this will happen with Slack, since the "trial/free" version won't last forever, actually will last only for the "first" 10.000 messages, and when you have a nice and collaborative team you will find that this number runs short very quickly.

The full package comes in a painful per agent per month price, but it's still a great business communication platform!

Overall: This particular software is very adaptive, and it actually helps you and your business to have a way to transmit information and data between every colleague without headaches!

At the same time it's pretty important to maintain a closed environment inside your business communications to avoid distractions, and this is very strict in Slack.

So overall it's a very nice business communications platform

Pros: Slack effectively removes all the clutter of "where did you put X at" and "where can I find the code for Y" conversations that filled your inbox at work. By using slack you can have all of those conversations online, which can also be retrieved later.

Additionally, through links, file sharing, bots, and other small features, Slack becomes a communication platform that makes your team FAR more efficient in how they do their day to day work. This is particularly helpful with remote teams, since video chat and screen sharing can allow them to feel as if they were in office.

On top of this, there are countless extensions, hooks, and plugins out there that bring your other tools, such as Bitbucket, Gitlab, Jenkins, TFS, etc) into your team through notifications so that way they don't have to have 5 tabs open on a daily basis to see if their code and been build and deployed successfully.

Slack has changed and energized how we work on projects here at work.

Cons: When using Slack for the first time it may seem a little too primitive or confusing, especially if there aren't a lot of channels being used by your team. It is good that you have to "opt in" to any channels minus a couple, but that can also make it confusing at first. After getting a few tips from the slack bot and starting to interact with your team, it will become more natural.

Overall: I use Slack with a number of teams on a day to day basis to help collaborate while building web applications and fostering ongoing learning within our internal initiatives.

Pros: What I like most is the ease of use. The interface is incredibly intuitive. Sometimes it's hard to get everyone on the same page when working on projects because we're all dispersed around the office and can't always get face-to-face time. Slack changes this. When an issue with a topic arises, we can quickly create a channel to discuss it and resolve the problem within minutes. The bot integration is also incredibly helpful and is leagues above any other chat service. For new team members who may have common questions that are easily answerable, we can program custom responses, so that the bot can respond instead of us (meaning time isn't taken away from other members of the team).

Cons: Slack has done wonders to reduce email traffic. Not everyone needs to be looped in or CC'd on everything and Slack helps narrow the conversation to those that need to be involved. However, the issue is that while email still feels like a formal communication avenue, Slack feels very casual. It basically just feels like you are chatting with your friends. This means that some things that you would never put in email (crude language, etc) can sometimes get a pass in Slack. This isn't so much an issue with the program as it is an issue with human behavior. So, before integrating it into your team, make sure to layout clear etiquette rules.

Pros: 1. Easy-to-use - Slack is so easy to use that you'll be up and running, reaping its benefits in no time. 2. Instant messaging - IM is a breeze with Slack. It is as simple as texting on your phone's messenger. 3. Photo sharing - With the click of a button, you can share pictures/documents with your team members. 4. Notifications - Slack alerts you every time you get a message from someone in your team. You can also choose to mute the notifications after hours so that you're not disturbed when you're not working. 5. Promotes collaboration - Slack really makes life easier when it comes to collaborating with your team. It saves time and helps solve vital issues easily. 6. Message search - You can find old conversations as and when needed by simply typing the required words in the search box. 7. Mobile app - Slack's mobile app is simple, fun and easy-to-use. It allows you to connect with your team from anywhere using any device.

Cons: 1. Threading - I've always found this to be a feature Slack could really improve upon. Comments on any message can be easy to miss due to lack of highlighting on threads. My team comes across instances where we need to comment on specific messages which it does allow you to do, but we end up missing important comments more often than not due to lack of notifications/highlights.

Pros: Slack replaced skype for us, for plenty of obvious reasons. Group communication is most usable feature apart from traditional one-on-one chat and comes with user friendly interface. Additionally, I like private and public group option as well. Another cool option is message threads so that folks doesn't get distracted from topic of conversation. These threads open in side pane removing the chatter away from main conversation. Thus, you can keep tracks of multiple conversation at a time. Other conventional features like Slack audio, video call and screen sharing is also of pretty good quality. Slack also integrated well with most of the third party softwares. You can configure things like jenkins job's result or Jira status change to be published on Slack. You can also have sassy Bots on Slack for different usages like identify on-call person or customer issues.

Cons: You have to fine-tune this application settings for better notification otherwise it can become annoying at times. Occasionally, this software crashes but their is no data loss. Slack is useful for quickly checking on things, but it is troublesome channel for detailed discussions. Some conversations run longer than needed because people type together. On other note, I also miss functionality of copying an image and directly pasting it in Slack.

Pros: Slack is simple to use so everyone can get quickly up to speed. There's nothing simpler for messaging and file sharing within teams. If anyone does have problems, they can ask the Slackbot and it usually supplies the answer.

It's easy to set up teams from different organisations - this is often much easier than trying to integration outsiders with guest access to corporate systems.

The ability to add in apps like OneDrive, Google Drive, Jira, Zendesk, GitHub etc., makes Slack a powerful system for ad hoc project teams.

Cons: This isn't so much a problem with Slack, but with all messaging/collaboration systems. Users need to be aware that the purpose of tools like Slack is to work together to achieve a specific outcome.

Tools like Slack can become a distraction and the ability to instant message can turn into office gossip rather than productive communication. Some users need education in the use of tools like Slack.

While we find Slack works well for small, committed teams working on defined projects, it doesn't scale too well with larger groups. There is just too much noise and it's difficult to see the bigger picture.

Overall: We use Slack for communication within small project teams, often working across different organisations and used in conjunction with other PM tools.

Best use case scenarios have been development teams working on Agile Sprints and event planning and execution.

Pros: This is the absolute best way to communicate with your team. Whether you all share an office or are across the globe, Slack makes it easy.

The features are endless:

-GIFs

-Private/public channels for everything from secret meetings to what's for lunch

-Messaging can be to an individual/group/whole team

-Stickers as reactions (you can even make your own and it's easy)

-Setting reminders (a real lifesaver)

-Your profile with more info in case someone needs to call or email

-Starting a call within any channel

-Jumping to a date to see something you missed from the meeting

-Search (because you're going to forget who you told about that thing)

-Did I mention GIFs (they're a blast)

-AND SO MUCH MORE!

Cons: There is the rare outage. These and far between and can last from seconds to minutes. Most of my team is within shouting distance so we're never hurting. If your team works out of the office this can be a period of aggravation. Again, it's rare. I see it happening once every few months.

Overall: This is not only a great way to communicate with the team but it's a lot of fun. Aside from making us more productive, it's a way to take a break. Have a conversation with a couple buds, go into the #random channel and share a funny story, GIF, image, experience. You can make a fun channel for something as silly as showing off sandwiches then try to one-up a coworker with your creativity in the company kitchen.

Pros: Slack has enabled us to give our employees more freedom and flexibility with when and where they work, without sacrificing good communication. As we have worked towards a goal of transparency, Slack has been an important tool. Best of all, Slack's wide selection of pre-built integration as well as ease to build your own if you're dev-savvy has turned it into the hub of all our internal business functions. We can get all our notifications in one place, easily get to wherever we need to go from Slack, and most importantly, not lose important conversations to the black hole of email.

Cons: Although the text-messaging feel that makes the backbone of Slack is something that just about everyone knows how to use, the finer points of really using Slack to the best of its capability for a business is a long learning process, and getting everyone onboard to integrate their functions in to help with productivity can be a struggle.

Overall: At first, only our Development team used Slack. After a few months, it was working so well for them and our team was growing quick, so we moved everyone over. At that time, we were 100% remote and after implementation our productivity and communications blossomed. Slack's customer service is superb, and they're always quick, knowledgeable, and kind.

At times we have had to work a little bit to make sure we and our employees maintain a healthy culture with instant messaging (it can cause unwarranted stress if not handled well, at times). Slack's do not disturb settings are helpful for this, but a business still has to be cognizant of the culture shifts that Slack is capable of causing to a workplace.

Pros: Pro, pretty much everyone uses Slack so use it once, whether you're a freelancer, consultant, employee, you're able to run with it wherever you go.

They have a web version and app version. It's easy to use web, desktop and mobile app versions.

It's easy to setup channels so you can focus conversations. One channel can be used for bug reporting, another channel can be used for the same team to share i.e., cool information you come across. Keeps unnecessary noise out when teams need to focus.

It's also easy to send files, images, audio. You can direct message people, review messages that are archived, search, pull files to attach from Google Drive.

Because Slack is so widely used, it really is great as a freelancer to not have to ramp up on how to use the tool. You just need to get familiar with how that particular team uses it.

Cons: Because I use slack with different clients and teams, it does drive me nuts to have to login separately to each team I join. That means I can have i.e., five or six teams that I have to individually log into. If you want to read more about this, I came across an article on Medium, search for "The Surprisingly Simple Thing Slack Got Wrong by CTO of Hubspot.

Notifications can be funky, at least they were for me. If you're new to Slack, take an extra minute to check how your notifications are configured, i.e., alerts via email, alerts on your mobile, or pop ups via your desktop app. I actually missed notifications and if you're handling multiple clients I highly recommend you test your notifications.

There's incredible functionality for free, so while these cons are annoying you can work with (around) them.

Pros: 1. Extremely easy to use. 2. Integrates with every single web app out there. For those who like to receive a live feed of Zendesk tickets, for example, it works wonders. 3. Easily connects groups of teams in their own private (or public) channels. 4. Do not disturb mode. I cannot tell you how important this is to your productivity. 5. Everything done in regards to the UI seems intuitive and the whole experience of trying to find something or setting up something just feels instinctive. 6. Highly customizable. Whether it's about customizing welcome messages, making your own emojis or making Slackbot do something for you, whatever it is you want to do with Slack, it just feels like you can. 7. Amazing potential of growth and many untapped features to find. Slack allows you to do so much (integrations, API, other paid features, ...). While other tools focus on being a one-man-show trying to offer everything in one place, Slack offers to be the maestro around whom every other piece of software (task management, project management, CS software, ...) revolves around, making communication paramount again.

Cons: It can be overwhelming and incredibly disruptive (in the bad way) in big teams. Chat conversations should be short and sweet, but there's a general tendency to barrage a channel or a person with questions and extend them way beyond what it should be the normal length for a chat conversation. Don't enable desktop notifications if your Slack activity is usually high. You won't be able to concentrate.

Recommendations to other buyers: Use the Don't Disturb mode whenever you need to focus or can't be distracted. Choose the channels you NEED to be in, otherwise you'll get called into Slack for something that you don't really need to know. Use it like you would behave in a normal, physical office. You don't need to poke that person in the back 5 times in 5 minutes asking if the thing is done. You don't need to shout across the room. You don't leave your files in a table (channel) that's not yours or that doesn't concern the people who use it. NOT everything is urgent. Learn to prioritize, delegate and trust people around you. Slack will be perfect that way.

Pros: Slack is a very useful communication tool in the workplace, it allows you to create discussions about a topic, a project or a particular situation in the company.

Among the things that I like most about this tool is that I can centralize communication with my work teams and I can integrate it with my suite of tools such as: Google Drive, bitbucket atlassian, trello, etc.

For me it is an intelligent chat that seeks to minimize the broadcast of corporate emails, however in my case it is useful but in the same way I can distribute the communications by several means depending on the need.

I often use private messaging and create channels by area to discuss a particular topic, and it allows me to connect via web, desktop or mobile.

Cons: What I find tedious in the tool is to search for conversations, although it has improved this section organizing it by topic, even I find it hard to locate information in a chat.

Another limitation is that it does not allow you to send videos in the chats, only files.

Overall: In general terms, my experience with slack has been very good, you can really reduce a number of corporate emails on a topic when you can do it through a chat channel and where everyone can participate.

In particular I can integrate it with hangouts and with drive making my management more efficient.

Another aspect of value is that when I carry out development projects, it is possible to take traceability through the applications of repository or version control with GitLab and Bitbucket.

I recommend it to all users understanding the content of centralizing their communications.

Pros: Slack is a great way to be able to communicate with team members in short, to the point messages that are more efficient than long email threads that take time to send, and that get lost amongst multiple replies. Channels can be public or closed depending on the team (allowing the flexibility to include or exclude departments / members from conversations unnecessary to their projects or workflow), and private conversations allow team members to get quick answers to questions that would otherwise disturb others or detract from threads.

Slack also has many great app integrations to make the workflow more efficient, including productivity apps like Asana, to morale-boosting apps to better engage employees and increase overall satisfaction.

Cons: The app isn't without the odd glitch or issue, such as notifications going unseen or notifications not disappearing once the message has been read, but overall the app works well.

The ability to send select channel messages as an email externally to make a proper record of a conversation could be a beneficial feature.

Overall: Overall, Slack is a great tool for communication, both with in-office teams and remote teams. It takes the ease and convenience of a messenger application and makes it tailored to the workplace, and its integration abilities with most other apps makes Slack an appealing and effective application to use.

Pros: Slack is so incredibly easy to use. It does exactly what you need and is not any fancier or more complicated than it needs to be. My company uses slack as our primary communication platform (the only other thing we have is Outlook mail but that's really only used for client communications and big operational internal announcements). The channels are incredibly convenient AND the fact that you can join and leave is always helpful :) We have them for internal teams for our system of engagement, different client teams, volunteering opportunities, social marketing, birthdays, general ... you name it. That's also how we communicate with our IT contractors. How easy is that? Send a message to them on our #technology channel and get a response right away (and sometimes others are having the same problems so it's a kill many birds situation). I LOVE that you can (easily) upload files and share articles. We have a #thoughleadership channel where we share interesting business articles out to the team, for example. I use the desktop version, but find the cloud version just as good. AND bonus the app for your phone is great. I use it all the time. I've actually started using slack as a verb, when I mean things like group text ... "Yeah, I'll slack the girls and see what they're up to." And by slack, I meant text :)

Cons: Absolutely nothing to dislike about slack. I love it. My company would be lost without it and it will never be replaced with anything. Period.

Overall: Fast, efficient, convenient communication, whether on my laptop or on the go. It increases the productivity of me individually and for my team immeasurably.

Pros: Slack does a good job seamlessly combining multiple platform types needed for team/company collaboration into a single tool (instant messaging, project management, bug tracking, file sharing, etc). Since it integrates well with popular, dedicated systems with more specialized functionality, it truly is a one-stop shop for running everything. In the end, all the features combine to keep the status of everyone and everything instantly accessible. The pricing model is very affordable, even for small companies/teams, and the free tier is robust enough that many teams may not need to upgrade to the paid plans.

Cons: Moving from a dedicated project management tool or instant messaging tool to Slack requires a bit of a relearning of some concepts. Direct messaging, public/private channels, etc. work a little differently. In addition, with so much functionality available, there is a learning curve on how to find and properly use various aspects of Slack that I found weren't completely intuitive. For example, without using the help guide I struggled to set up and send a new direct message. Finally, if you're drowning in notifications and email, Slack can become overwhelming depending on how your team uses it. For the platform to be effective, ongoing use by every member of the team is necessary, and the expectation of instant response can easily form, which can turn this very useful tool into an impediment to your workflow and productivity if not managed properly.

However, this easiness covers lots of useful features that will uncover once you get accustomed with simple features and start to explore slack more.

Besides that, slack allows you to install additional bots and plugins that will help you even more with automating mundane tasks and everyday routines.

Cons: I noticed that with slack I spend more time on communication than before. Unlike email, you can postpone answering a message, you need to answer it immediately, otherwise it'll get buried among other chats. Also slack is a closed world of its own. When we used skype in our company, it was easy to create conferences with people from different companies. You can't do that easy with slack, you'll have to ask your admin to send an invite to the person in slack, otherwise they won't have access to it.

Overall: I remember times when there was email only. Then came ICQ and it speeded things up. Then skype appeared and became a de-facto business standard. However, even during skype domination I've heard about a new messenger called slack and wondered: What's the sense in a new communication tool? Only after I started to use it extensively I realised how convenient and powerful it is. I really like using slack now and can't understand how we used skype before :)

Pros: I used to use Skype for business communication... And Skype was the worst. I had no idea how much better it could be. Skype had issues left and right. Slack showed me how much better communication software can be. It is so much more user-friendly and intuitive to use. When starting to use Slack it will guide you around and show you how to use it as you go. It has so much more functionality than alternatives. It is very reliable, and the desktop app and mobile app communicate with each other very well when you're switching back and forth between them. Sharing files is easy. The search functionality is great. Customizing your notifications is great. Setting up different threads and channels are very useful

Cons: Honestly, it is pretty hard to think about what I like the least. Slack is an excellent piece of software and their growth numbers illustrate it.

With that being said, Slack can sometimes be confusing because of how many different functions it can offer. Slack can integrate with other software programs and it can sometimes get confusing.

Having good Slack etiquette is a thing. People need to kind of be on the same page of how to use slack so that way they aren't blowing up other peoples notifications. The different threads in a conversation can sometimes be confusing for some employees.

Pros: Nothing slows down your workday more than being bombarded by emails, particularly internal emails. One thing we do to reduce clutter is move all conversation into our online communication tool, Slack. Slack is a free online messaging service that brings all our communication together in one place. It's real-time messaging that even pushes to your phone when your computer is idle. Up to 10,000 messages are stored at a time for searchable chat history (more if you upgrade from the free version). You can split up your communication into channels meant for those who need to see it and it runs in the background of your computer without notifying you unless someone is talking directly to you. Slack allows you to star messages that forms a follow up action item list, add reactions to a message that allows the sender to know you have received it without the extraneous got it and thank you you get via email, as well as make conference calls/video chats directly inside of the program. We also integrated our online project management tool, Trello, into Slack that pushes real-time project updates for all to see as various team members check off items.

Cons: Very hard to find a con about this software! It integrates with so many features. Pricing is also very reasonable

Pros: Slack's policy to always offer a free plan is a god-send for micropreneurs on low budgets. In addition to my own account, I create branded accounts for each new client to manage their design and website projects in one place. No more missed or lost emails, no lost design files; easily shared and edited text documents ....and so it goes on. I can't recommend it highly enough. Stand-out features: comprehensive range of integrations; generous amount of storage; excellent search engine; good archiving; ease of switching between accounts and channels, well designed layout and UI, brandability etc.

Cons: Slack's settings and tutorial pages are a little convoluted to navigate. Although it seems so simple once you know it well, new users sometimes struggle to find their way around and need quite a bit of encouragement to stick with it. For example, I often have to explain things that should be obvious, such as making a shift return to create new paragraphs instead of creating lots of new messages. No doubt these minor niggles are a result of the app's organic growth and development since it launched. The only thing that's ever annoyed me is that you can't bulk delete Slackbot DM's. They have to be deleted one by one. If I'd known that, I wouldn't have used Slackbot for automated updates via a Zapier recipe!

Pros: Using Slack is easy. Most of the functionalities are explained on the actual software, too. I use it to connect with a large group of coworkers from all over the globe, and I find it really useful that I can see user's local time by just clicking on their names. The pinging and notification tools are also quite helpful. I like the way I can share videos on it too, as they can be played right from the platform. I like the fact that a company can personalize slack to a degree where icons and messages are related to it, too. Finally, the search function and the "unread" tools are very helpful. I frequently use search to look for something across all channels, and it's easier to keep up with news when I come back to the platform after a while thanks to the fact that any new messages from the last time I viewed a particular screen are marked as "unread".

Cons: Well, this is not actually something that the software is responsible for, but there is something as too many notifications. It makes it difficult to relax sometimes. I wish I could mute notifications of a specific channel. The fact that messages expire on the free version is something that really bugs me, but I understand that the firm needs to make sure that there are SOME functionalities that people have to pay for, so I get it... still, the group I work with is quite large and the paid plans are charged per person, so we are not able to get one. I wish there was a fixed paid plan that would prevent messages from expiring regardless of the number of people working at any given time.

Overall: I use Slack daily to communicate with a fairly large team.

Pros: I love this app. I started using it as my co-op mentor used it to organize group meetings and also to private message me. After graduation, I still used it but switched workspaces entirely leaving the old behind. In Slack, I can organize projects by #channels and my @partners working on projects can chat about developments which everyone can read and importantly have a permanent record of. We integrated it with Freshdesk to ensure customer requests are handled promptly when I worked for one company and the best use is my integration with IFTTT. I had D-Link motion detector plugged in the common area as my former landlord would always sneak into our suite and I would always have a few seconds of advanced warning to put on more clothes just before he appeared. Importantly, I had a record on my #motionsenor channel that someone was creeping outside my suite usually in the early hours of the morning. Now I manage a few cloud servers and with webhook integration, they report their progress on tasks to me and all I do is sit back monitor them.

Cons: I actually do not have any issues with Slack. I use as one of my many apps that I use and may not use all the functions available and also as I am on the free plan am limited to the number of intergration with other apps that I can do.

Overall: It is best used as a chat channel with humans or as a place to integrate on the various channels your communication with devices and servers which report to you.

Pros: Slack lives up to its promise; it replaces email for a lot of conversations. Especially conversations that require a lot of back-and-forth, but don't necessarily require arranging a meeting.

It's been the linchpin of communications in all of the remote workplace jobs I've had. Since companies that use Slack tend to "live" on Slack, it's a great way to make people and information easily accessible.

It's nice that there are so many integrations (e.g., to get alerts when certain triggers are tripped, like, for example, when a customer support question comes in but hasn't been assigned), but frankly, just the basic conversation and file-sharing functionality creates most of the value (in my experience).

The addition of video conferencing has been really handy, too; rather than fire up another app (like Zoom), it's easy to create impromptu remote meetings.

Cons: The downside of having a place where so much of your workplace communication happens is that you might find yourself spending an inordinate amount of time in Slack. That is, past the point of productivity.

It's a bit like a social media app in the way that you can develop a habit to check your Slack feed obsessively just to see if there are any interesting tidbits of conversation that you missed.

Pros: Slack is a great real time communication tool. We have tried many other alternatives and keep coming back to Slack cause it just works. My favorite things about it include: 1) Easy communication channels. We use these for different departments or groups, this way you can keep up with your colleagues across departments and view messages specific to subjects or departments. You can find unread messages that are grouped for you, also reminders specific to channels and more. 2) The free version is not that bad. Most apps that provide a free version, make it handy capped for you to use. Yes the archived messages feature is missed (but its worth paying for), but overall you get a lot out of it to be able to make a decision whether to pay for it or not. 3) Integrations - Slack integrations make it easy to turn Slack into a virtual workspace. The Slack marketplace has many options including many project management tools and bots that you can create.

Cons: Slack is not all rosey and our biggest con with it is the connectivity problems. We tend to have calls dropped and screen sharing sometimes doesn't work despite the reconnect function. Also as with most modular tools today, it is easy to get distracted by some of its features like bots and the integrations can become overwhelming if you are setting it up. The learning curve is difficult for new users and it takes some time to orient a new user.

Pros: A free option is available but it is supplied with limitations. The chat feature is pretty solid and the main reason to use Slack. It is designed for internal businesses or departments in mind and provides group channels and the ability to chat with multiple users from one window.

Cons: Free version is limited to 10,000 messages a month and will delete messages once this limit is reached. Creating new chat sessions can sometimes be tricky because the software will only list a handful of your most recent discussions and this can force the user to search for a particular user before they are able to initiate a chat with them. This can be difficult if their full name is not available or known. The company directory is not place in an intuitive location and can be difficult to find when a list of all the available contacts is needed.

Overall: It's a solid chat program to allow teams to collaborate. The desktop app and web-based options are useful when not using a personal computer. The phone app also allows a user to be available when they are away from their computer.

Keyboard shortcuts make certain tasks quick to accomplish and bots can also be used to automate certain events.

Overall it is a good option for many businesses that only require communication within their organization. Adding outside users can be risky and I would advise creating another "workspace" to handle any outside of organization communications

Pros: Slack is incredibly easy to set up, has a pretty solid free version, and is pretty intuitive for people new to online collaboration and communication tools. You can do simple calls in the free version; video calls in the paid version. You can create private and public channels, integrate many tools within slack, and set up bots for routine questions and actions. One of the best things about Slack is it's reach. You can quickly set it up and reach across organizations with it. But what everyone in our org loves is the ability to custom make emojis! Anything that adds a little fun to the workplace gets a thumbs up from me!

Cons: Slack does not do everything. It does not replace teleconferencing software or document management software. But it allows so much that people end up using the tool for purposes it just isn't great at. If I compare Slack to MS Teams from a business perspective - I would go with Teams. Slack is not backed by a document repo with structures and tagging for the documents. It's good for one on one calls but not for group calls.

Overall: We are using Slack as a chat tools as well as a collaboration tool. The teams that use it simplistically are very successful. It's a good tool that can be spun up very quickly and can bring together groups of users who are not in the same organization.

Pros: 1. Integrations. I have seen all sorts of integrations into here (server monitoring status updates, checkins, builds, etc.)

2. File and screenshot handling. Drag it in or paste it in and it uploads painlessly. I do this multiple times a day and haven't run into an issue yet.

3. You can make as many channels (think group chats) as you want and add people to them or restrict who can get into them.

4. Messages send to offline users! If you have used MS Skype you should know this pain. If someone is offline you can't send them any message until they are back online. What chat app nowadays does that?

5. If you aren't signed in and you miss a message then you get an email with said message/grouping of messages. I found this to be pretty useful since I am not always on or I miss the desktop notification and don't check for a while.

6. I read that they have video chat and screen sharing but I haven't tried this out yet, my company may not pay for that feature.

Cons: 1. At one point I wanted to add a temporary user for interviewees to have a direct channel to the hiring manager during the day but I didn't find an easy way to do that besides have some permanent user and handing the login info out. Most people probably don't need this.

Pros: I loved using Slack. It allows you to easily keep track of files and conversations. You can create any number of group conversations and maintain control over who is able to see them making it a great tool for connecting with project teams, departments, individuals and clients. You can even include groups outside of the organization such as those used for trading ideas about industry topics without affecting anybody else slack group. It has a number of useful and fun functions from file sharing and comment tracking to goofy gifs that help lighten the mood. It lightens the load on your email inbox and allows you to connect remotely while enjoying the benefit of professional conversations, water cooler talk, and team brainstorming. It is easily searchable and is a tool I miss quite often now that I am working for a company that does not use it.

Cons: The version we used often ran out of space and I spent a lot of time deleting old files one at a time. It was very tedious. It is a bit distracting when you are in the middle of something and there is no way to discern from important chatter and simple noise. It is also not great for everyone especially team members who like traditional means of communications. This last issue can end up creating confusion if you are using multiple mediums to discuss a single topic.

Overall: Overall this software is easy to use and incredibly helpful in streamlining conversation.

Pros: Similar to what Discord did for Gaming VoIP, Slack did for the professional communication ecosystem. At its core, it is a text, voice, and video call platform in the same vein as Skype for Business. Slack differentiates itself by being a very feature-rich and easy to use platform for communicating with teammates and clients with many built-in features such as a reminder system, code sharing system, and robust channel management system. Even more additional modules integrate with Slack, like Dropbox, Google Drive, Github, and BitBucket to further enhance Slack's functionality. It's available on a variety of platforms as a web app, desktop application, and mobile app so that all team members are always in touch. An official help center and support channel exists for Slack users, with many Slack users supporting one another.

Cons: A company or team must be willing and receptive to using Slack, as it may require adjustment from the current communication channel. The free version is capable but a little limited; that being said, you definitely get your value out of a paid version of Slack if you need the tools and features afforded by the premium versions. Slack is being developed quickly, so while bugs and oddities exist, they are quickly fixed with new features being added frequently.

Overall: I use Slack in small academic teams, small non-profit organizations, and at my job and am thoroughly satisfied with it.

Pros: Slack is a fantastic tool for team communication. You can create multiple channels for different topics/teams/projects. You can have your random/social discussions (e.g. fantasy football, politics) in channels separate from the rest of the important stuff.

There are lots of integrations that can be added.

Easy to upload files, pictures from Dropbox/Drive/OneDrive/local.

I really like the customizable emojis/reactions.

It allows for light-weight communication (like an IM) as opposed to heavy communication (like an email). @mentions makes it easy to make sure relevant people see what you're trying to communicate. You can comment on a post (creating a sort of sub-channel) without it interfering with the rest of the discussion.

Keyboard shortcuts.

Cons: There are restrictions (or at least cost barriers) to the number of integrations a team can have, amount of files/posts that can be maintained, etc. It would be nice to have a mid-tier pricing that lets you mix and match integrations, users, post-storage, etc.

There has been a lot of development in the team communication space and Slack was the primary driver of that. It will be interesting to see how Slack adapts to all of the new features being developed by other solutions. Features I would like to see: snoozing notifications, decisions, task creation/assignment (aka actions), ability to embed a channel into a website/intranet team page, groups, and sub-channels.

Overall: Easier, light-weight communication. Easier/cleaner than email. Get info from whoever has the answer, not just who you think has the answer.

Pros: First of all, our team found Slack to be intuitive and easy to use (beginners, non-techy, old and new employees alike).

It housed all our project communications (direct/group messaging, sharing of files, etc.). It also comes with notifications (depending on your settings) so you'll be notified via email as well.

Slack also comes with a mobile app (I use it on Android both in my smartphone and tablet, but also comes in iOS). We also use it by default in our desktop/laptops (both Windows and MacOS), and well, also is accessible via web browser.

It works well also with other apps (Third-Party Integration). We connected it to our visitor management system (Envoy) and we get notified about our visitors in Slack as well.

Slack makes life easier for our new hires. They can just join in our project channels and from there, they can go back in time to read thru our past communications

Cons: Well, the free version of this app limits you to seeing and searching up to 10,000 recent messages/entries only. This means you won't see historical data beyond the limit unless your team subscribes to the paid service.

Overall: Slack provides an easy-to-use platform for project communications. It housed all our messaging and files shared among team members.

Pros: The good thing about this tool is that you can access it from multiple platforms and devices. It supports both Mac and Windows and you can choose to access it from your browser or by installing the application locally.

In my opinion, the installed version works best, as happens with most similar platforms but the browser version provides you with the option to access anywhere you are.

The mobile versions of the tool work very well too, so that's definitely something to take into consideration.

One great thing about this tool is that you can create multiple channels and make them private if needed.

One other feature I found extremely useful is the fact that you can create reminders. These can come in multiple ways. To name a couple of options, you can set a reminder for a given message that you want to revisit the next day, for example. Or create a reminder to alert you every Thursday of your one-to-one meeting with your coworker.

Cons: The way you can enter emojis and format your text can be tricky at first if you don't know the tool, but once you do it's actually really fast to do so. On the plus side, there are multiple formatting options as strikethrough, bullet lists, code blocks or blockquotes.

Pros: As a freelancer, I work remote for a company who is disperse over 6 different cities. Slack has been invaluable to us as a team to maintain quick and organized communications. My favorite feature is are the channel options. It helps me quickly reach the correct members of the team and helps me more easily refer back to information or conversations from the past.

I also love that we have the ability to search for keywords, this has helped me numerous times when I can't remember who I had a certain conversation with or the details, etc.

Another feature that is really handy is the app, it helps me stay connected on the go so that I don't ever feel like I've got a lot of catching up to do when I finally make it back to a computer.

Cons: The only issue that I've run across is receiving notifications on my phone. Sometimes I do not get a notification, even when I've been tagged or directly messaged, and I'm still trying to work out if this is an issue with my phone settings, or app settings, or if it's just a small bug in the app. But in the grand scheme of things, this is a minor issue and I can work around it by checking in throughout the day if my app notifications seem unusually quiet. Other than that, no complaints!!

Overall: Quick & easy communication, easily able to locate past conversations, on-the-go communication (being able to stay connected with the team), organized communications w/ the channels feature

Pros: There are quite a few chat apps out now - Teams ( free, sort-of), Discord (not just games), Google Chat ( free for some), Skype ( Dead), Line ( garbage).....

Despite some of these being build on the same basic platform ( Elektron), Slack works the best. I have used them all, and Slack is the most reliable, and easiest to use. It works the same on each platform ( Windows, Web and smartphone)

Cons: At last check the screenshare/monitor share function doesn't work with multi-monitors. Slack is the best of class app, so there's a free teir (10,000 messages IIRC) and then a paid tier. It's worth it.

While I understand the intent of the design, I'm not a fan of the Conversation Threading Method in Slack. It does work and is fairly intuitive, but Microsoft Teams did it one better.

Some days I wish categories/channels could have sub channels

Overall: Slack is another mode of communication and when used at a team level can be used in lieu of Texts & any IM platform. Messages can be categorized ( channels). DMs can be used - it can be limited to your org, or shared to many. It can be the primary communication medium for any team, and if you start to use it regularly, it can replace email. that's it's big selling point -- Although Be careful, it can quickly become "One other place to have to look for something" if you're not careful

Pros: 1.It's reliable- there are no issues sending/receiving messages. Unlike text messaging, there's the assurance that messages are sent and received over an internet connection

2."Channels"- within an organization's chat, there can be channels or "sub-chats" where only a certain group of members within that organization can have their own chats. There's no need for multiple messaging apps- all the group chats are organized on one app.

3.Flexibility in snoozing messages- one of the best features of the app is that you can choose how long to snooze messages- 20 minutes, 1 hour, 8 hours, 24 hours, or even just turn them off indefinitely

4.Emojis- you can react to messages, expressing approval, disapproval, or even a confused face!

5.Lots of little things- ability to star messages, pin messages, and edit sent messages are all little things that make the app just that more useful. They're nice touches that set this messaging apart from other messaging apps, and hard to use other apps because these are so useful.

Cons: The only real "issue" is the slight learning curve- the app feels overwhelming when you first take a look at it, especially when figuring out what "channels" are and what its purpose is.

Overall: Overall, however, Slack is a very polished app. There's not much to complain about- it not only gets the job done, but adds additional small touches that set it apart from other apps.

Pros: Slackbot acts like a helper, we can get any help for any task.

we can integrate many other apps like gmail,dpd, skype , so it acts as an all in one tool

can share rich contents including images, files and specially code snippets

customized search functionality

can schedule work with slackbot, and it sends notlification reminders.

Channels helps to continue various conversations at the same time without interrupting other conversations.

Cons: No voice communication methods

Not much good for project planning

No calendars integrated

Sometimes the search function is not working properly

Overall: I am working as a software engineer and we are using slack to communicate with the team. we have separate channel for each project. I have experienced that this tool is a very good method for team communication.we have integrated many more third party apps with slack, so we are getting all the notification from gmail, dpd, carnban board etc. we share images, videos, emojis directly and in public. as we have integrated many tools, we take it as the only communication method in our team. Also we set reminders scheduling future tasks. A we can join various teams, it is easier to manage communication. sending program codes as it is, and ability for searching previous messages are very valuable functionalities for me as a developer. If there were voice call functionality, it would be a 100% perfect all in one tool.

Pros: Easy to add anyone to a slack channel, regardless of email address or affiliation with business. I use this app to talk to colleagues that are not necessarily in the same company but I still consult with on a daily or weekly basis. It's great for having casual conversation throughout the day and is much less disruptive than a phone call or something like Facebook messenger, which connects you to the entire world of social media. I like that I can send GIFs and media files, as well as emojis, and that the chat notification pops up in my side corner like an email preview. I like that there are quick links to other channels so you can easily hop between without logging in and out every time.

Cons: The window for the chat is HUGE. If you shrink it down to a manageable size, it loses functionality. This is really my biggest complaint about slack. Even in the most compact version of the user interface, the controls are huge, and there is not the option to hide certain of the sidebars.

Overall: Slack gives me the ability to quickly ask questions of coworkers who might not be available over the phone or use email in a more formal way. It provides a more informal chat environment where I can problem solve but it is less demanding than physically being at someone's desk. It also allows me to connect in a casual way with coworkers who work from home, helping to create a more bonded team and an intimate environment where we can ask about home life etc despite working remotely.

Pros: Slack can be as simple as a basic messaging system or as complex as you make it. We can be as creative as we want with Slack through using integrations while keeping basic communication present throughout our team members. For example, our office has a Slack channel that calls out different co-workers randomly throughout the day with quick exercise tasks (like - Hey Amber! Do 5 jumping jacks!)

It makes talking to each other and communicating fun whether we're working on a project, planning a new office culture event or asking a co-worker a quick question. We're trying some fun integrations like Busterbot (workout app mentioned above) plus we're keeping our work on track with Hubspot notifications for marketing & sales in Slack. Lastly, creating unique channels for our projects helps keep communication in line and we can share messages, files, images, etc. in one spot.

Cons: Honestly, I can't say one bad thing about Slack. Our office wouldn't function without it and I would seriously recommend trying the free version.

Overall: Fast & easy communication between co-workers, departments and committees, helps keeps communication silo-ed into different channels for projects, fun integrations & serious business integrations both available.

Pros: It's intuitive to use thanks to a good, slick interface. The separation into channels and chats is not unusualy, but I always liked that it's on the same site (I'm referring to the desktop client, mobile is a different story of course).

Threading within the chats was a bit confusing at first, but overall I'd say the benefits outweigh the issues. Still, it can cause a lot of confusion when the order of threads keeps changing because people respond to them in different order.

What I really appreciate about Slack is the possibility to heavily customize the alerts. You can have specific settings for each channel and distinguish mentions and keywords used. This goes for both desktop and mobile versions and allows to make sure that you only get those notifications that you really want.

Cons: One of the biggest issues we had with Slack was disappearing "unread bubbles". If someone started a thread and you read the beginning, if that person continued to write while you were active in the software in some other channel or chat, no new bubble would alert you to the responses. If you had responded to it earlier, that would be different. But the original thread creator could write his or her heart out and you wouldn't notice...

Also, since there is no way to group chats other then by channels and threads, things can get a bit overwhelming when you have a lot of people, teams or simply a lot of information flow. That's why I prefer Microsoft Teams, where you have the team category as a nother organizing structure.

Pros: For both CEOs and interns, it is an effective communication strategy. Integrations such as /Giphy create a great culture and atmosphere, adding context and voice to each person's slack message. The ability to add in your own emojis and personalize it for the company add to the overall culture that slack creates.

Slack has reminder features as well as threads and individual message response. Slack's potential can be defined by the company itself, as one will need to make sure a standard structure is followed in the group chats (called channels).

Cons: The long string of messages can be cumbersome. At times, employees are apt to send slacks when it should have been a message. I wish there was the ability to forward a message as an e-mail or respond by e-mail.

The search functionality could be much better. I would like the ability to search attachments in certain chats, time received, etc. as the history of messages can end up getting an item lost in translation. Perhaps folders to put certain items/messages in would help.

Overall: Communication via slack is easier than that of text messaging. Not only does it allow for private group chats, but it creates the ability for employees to prioritize messages and filter unnecessary conversations.

Pros: Slack is the hub for office communication and the savior of de-cluttering email.

Slack is free for teams up to a certain size (around 30, I think) and requiring a certain amount of cloud storage for shared files, messages, etc.

Slack's interface is organized intuitively into "channels" within your workspace. You can message people directly, message groups of people, or message "channels" (which could be teams, interest groups, or whatever else).

Slack was built for developer teams, so sharing snippets of code and pre-formatted data is a breeze.

Slack also integrated with popular apps (like Google Drive or Asana, to name a couple) to be the hub of all things going on in your office. Slack will let you know when someone shares a file with you, or when a new task has been assigned to you.

Without Slack, our business would be bogged down by email and inefficient communication!

Cons: The free plan hits a storage limit, so older messages will be deleted if you do not pay for a plan. The plans are per-user per-month and pretty reasonable, so this is a minor inconvenience.

Overall: We use Slack to streamline business communication and without it, we would be significantly less efficient communicators.

Pros: Very easy to create groups of users, so only selected users take part in the conversation. Integration with web apps like 'Trello' and 'GitHub', so we receive notifications when something is actioned in one of those particular applications. Nice user interface, very easy to use and get to grips with. The buttons make all the functions clear to the user right from the start. Slack also has access to various 3rd party apps like 'RightGIF', so you can even include GIF's in your messages! Their web-based help page is very detailed and easy to use, although the in-app help isn't good.

Cons: The notifications you receive from web apps like Trello can sometimes get too much, as you can't control what notifications you receive so you get a pop-up whenever the smallest change is made. The search function could definitely be improved, as it can near impossible to find historic messages. Which has resulted in some confusion. The built-in 'Slackbot', is almost useless. If you don't already know the keyboard commands to interact with it, all he does is tell you to go to heir help page. When a group is set to 'Private', the notifications that a message was sent there are very well hidden and can be easy to miss.

Pros: Slack creates an office like vibe for my team as we all work remote. Its great to have an open chat going to give an avenue for small talk OR for business needs. Slack goes above and beyond what email or text can do for communication because you can create channels to ensure the people involved understand the topics to be discussed in each channel.

I LOVE the searchability function in slack to make it easy to recall things when my memory gets foggy. I also like that you are able to delete things from a conversation if something gets way off topic and bogs down the chat line.

Cons: Slack can sometimes get glitchy if you are not active on it daily. If you go offline for a bit then come back on after a few days its like the app needs a minute to catch up with all the chatter you may have missed.

Slack can be harder for people to adopt if they are averse to office chatter in general. Having too many modes of communication going for a remote team can get counterproductive (slack, salesforce tasking, email, text, phone call, etc.). Be sure your team understands the purpose and intended use for slack before adding it.

Overall: strengthening team relationships through more regular communication of a remote team.

Pros: Obviously it's main purpose for easy communication 1:1, within a team, team:team, and company-wide, and for that it's faultless. But there's also so many other time saving features which I've found invaluable in my day-to-day work life.

With the paid plan all history is saved, so it effectively becomes a knowledge base - whenever there's something I don't know the answer to, I'll search it in slack and more often than not someone else has usually already asked the same question on one of our slack channels so the answer's right there!

The thousands of apps mean anything you want to do is likely do-able - there's too many good ones to list.

/remind is my go-to shortcut utilised about 100 times a day.

It's also just a really great for keeping everyone social and morale high without the need for people to leave their desks, so everyone can be sharing a laugh with minimal impact on productivity.

Cons: I can't think of anything I don't particularly like, but we have had some trouble with people making what they think to be private channels that are actually openly available to the company. Mostly I think this is a training issue, but something to keep in mind

Pricey but I don't care, a perfect team communication!

Pros: The best aspect of Slack is that it is platform agnostic.

Our company got onto the private chat bandwagon more than a dedicate ago with Apple's in-built XMPP server. It was fantastic and never a problem... while we only used with internal staff that had been issued company maintained computers. A huge headache for us came about with adoption of smartphones, tablets, and us expanding our operations to remote non-apple contractors.

Apple's XMPP server simply didn't work smoothly in that environment. Something that made our powers-that-be very frustrated, "it's Apple, it should work!" not realizing that they were waving around a Blackberry.

But now we have Slack! And it just works simply and beautifully across all devices and users. The boos now can chat with staff while on the road while remote contractors never have an issue installing and setting up.

Slack allows us to have incredible granular controls along with productive (Trello, Google) and fun (bitmoji) integrations.

Group chats and channels allow us to also communicate as a team far better than XMPP every did.

Cons: The price.

Stride is half the price but I haven't been able to get enough staff to use it so we're with Slack and being a small/medium business, going from "free" with XMPP to paid per user per month is a sore spot.

Pros: It's intuitive to use, since most everyone is already familiar with chat / IMs / etc. which means one key part of successfully using Slack has been easy: getting everyone else at my company on board (what's the use if not everyone uses it?)

It also has some great integrations, so I can get instant updates on other aspects of work, like comments in Google Docs or website deploys. Overall, a great communication tool.

It's also easy to search for files or information someone shared with me in the past.

Cons: It's not great at keeping track of actionable requests or something I want to take care of later. Especially when requests come from multiple different people (and I want to collect all of those request in one easy to view to-do list), it's way too easy to forget. I know Slack is trying to build up emphasis on this use case, but I don't think it's there yet -- and may never be. For that, I use Asana and don't ever see Slack replacing Asana -- Asana's capabilities are far more developed for work management / keeping track of projects and tasks. But used together, I've got all aspects of work communication and collaboration covered.

Overall: Instant communication with coworkers and a clutter free email inbox.

Pros: I have used Slack for a long time to communicate clearly and effectively with various teams that I have been a part with. Slack allows us to communicate quickly and efficiently to ensure that everyone knows what they must be doing and when they should do it. You can easily create channels, groups, and even assign group member's roles to make sure they know what they are doing. Slack offers an App, as well as a desktop site, so you can communicate with your team virtually anywhere. Overall, Slack is a fantastic program to keep in contact with a team to ensure the build quality, and the time efficiency is kept up to standard.

Cons: With many apps on the market today, Slack sometimes stutters or buffers if too many messages come in at once. On more than one occasion I have not been notified of a message in my group's Slack group because the app failed to notify me. I understand that there may be problems here and there, but when the message is an important one, it gets exceedingly frustrating to keep putting up with it, as I need to know what is happening and when it is happening. Overall though, it's still a fantastic app with just a few bugs that need to be worked at here and there.

Pros: Slack is the most amazing collaboration platform I've ever used. Better than e-mail. Better than texting. Better than instant messaging. And it is seriously intuitive. Slack is a collaboration platform with a ton of available integrations, so you can make it an instant part of your office routine. Think of it as Google Wave (remember that?) if it had been done right (it wasn't). I've tried a wide variety of tools that should have been as easy to use, but only Slack helped me achieve collaboration Nirvana: real-time, always on, anywhere communication, file-sharing, notification and more.

Cons: With all its flexibility and available integrations, Slack can be a little overwhelming. Also, the interface (at least in the free version) is a bit too simple for full-on collaboration on sophisticated projects. In essence, Slack is better than e-mail, permits the real-time communication of an instant message client, but preserves conversations like texting (or Twitter). So if you are not careful, it can make a complex interaction even more complex, and confusing.

Overall: Overall, Slack has improved communication and document sharing in my small office (3 users) immeasurably. No diggity. This software was a revelation.

Slack is a robust and mature messaging and collaboration platform with no barrier to entry.

Pros: My favorite feature of Slack has to be the webhook integration with bots. Being able to configure a 'robot' to pop into a chat room and deliver important information in real time is as useful as it is cool.

The availability of a free tier is great for those who want to see how Slack works, and it isn't crippled version. Webhooks and bots are available, and messaging gateways to support IRC and XMPP make it easy to include legacy messaging systems, or let users remain on their preferred open platform without being excluded from Slack.

Thanks to its popularity, many people are already familiar with Slack, so it is pretty easy to find people that are already using it.

Cons: It's proprietary software. My preference is always weighted heavily toward open source solutions whenever possible, and the messaging and collaboration space has no shortage of excellent open source options.

I'm also not a fan of 'needing to install Yet Another Messaging App'. Luckily the way I use Slack is compatible with the XMPP gateway feature, so I can just connect to that using Pidgin.

Overall: The chief benefit I receive from Slack is the ability to communicate with one of my vendors, and to receive status from bots using webhooks.
