GMass was a game-changer for me in the world of email follow ups and automation

Easy way to send personalized emails to lists of prospects or contacts

Likely Extremely
Likely
Pros: It lets you send personalized emails (mail merged from contact lists in Google Sheets) via Gmail, up to 2000 contacts/day for trusted G Suite users. Gmail has much higher deliverability than email marketing platforms, which translates into higher open rates.
A lesser known useful feature of Gmass: you can also set up and send a drip nurturing email sequence to prospects and automatically stop it for any prospect based on their behavior (opened a link, replied to the email, etc.). This essentially works the same way as more expensive outreach automation tools, only there is a deeper learning curve with Gmass because you have to set up everything via its interface directly inside Gmail.
Cons: It would be helpful to have the most up-to-date email open, click, unsubscribe and bounce metrics integrated with the Google Sheets of contacts the email was sent to. Instead of receiving email updates with these metrics.

Integrates Well into GSuite

Likely Extremely
Likely
Pros: Pro 1: has a great free version to try out
Pro 2: Reliable delivery
Cons: Con 1: Sometimes throws an error when clicking the Mail Now button, so I schedule the email to go out in a few minutes
Con 2: Would like to use it other browsers, not just Chrome (it's a Chrome extension)
Overall: GMass is fantastic to see if clients open emails, and it also is handy to email small groups of clients. I highly recommend trying this feature.

The one software I would never want to be without


Likely Extremely
Likely
Pros: Ease of use! This software is super easy to set up and begin using for anyone of any tech experience level. I love that it connects with Google Sheets so seamlessly
Cons: The only thing bad about the product, at least for me, is that everyone is finding out about it ;-) It was once my little secret - haha!

Marketing emails straight to the inbox!


Likely Extremely
Likely
Pros: I've been using Gmass since it started about 3 years ago and I can confidently say that it has grown my business tenfold! Our company was just getting started on marketing emails when we came across this new Gmail plugin Gmass. It was a bit overwhelming at first to figure out because there are so many features but there is no simple dashboard to learn. You have to read through blog posts and take notes but once you get the hang of it, it's well worth the time! And whenever I've had trouble with a campaign, the customer support has been right on top of it. Thanks to the executive!
Cons: I'd love to see a dashboard with a simple UI.
The ability and functionality that GMass delivers was a game changer for my business!

Likely Extremely
Likely
Pros: I love the ability to build upon it's platform, the ease of integrating it into GMail and what my business was currently doing and expanding too! GMass has become an essential function of our marketing tools and it's ability to easily connect to our databases that we manage through Drive.
Cons: I have yet to find anything that would discourage me from utilizing GMass. Issues I have run into have been resolved in reasonable amounts of time given the support chain. If you are not the type of person to "DIY" an issue i.e. read and troubleshoot from blog posts, and want to integrate this software; then I would only suggest to be aware support will only come in email form or from reading through others experiences! It's abilities to take the "sending & scheduling & follow-up" into more an automatic flow is also a great tool!
Overall: Has allowed my business to grow since it's inception. Has changed the dynamics of our abilities to mass communicate!

Gmass is amazing, it allows me to save so much time sending out email to lists of candidates.


Likely Extremely
Likely
Pros: I can automate my emails with ease, it allows me to save so much time sending out emails to lists of candidates and basically automate the entire process.
Cons: The UX takes a lot of getting used to and there is a learning curve. Other than that I really have no gripes with the software.
Overall: Automating my emails to the point where I actually freed up a good chunk of my time.

I've had the best experience with gmass personally. Easy to use, plenty of functions, great


Likely Extremely
Likely
Pros: The fact that I can use it with my gmail account so the deliverability rates are extremely high and reliable.
Cons: I honestly don't have any complaints. They even updated it so you can't accidently send out bulk emails to separate accounts
Overall: I got the benefit of extremely helping with my email marketing thus leading me to be in contact with thousands of local businesses
GMass has changed the way we market!

Likely Extremely
Likely
Pros: Highly intricate features to track and analyze an outgoing email both before and after send. Easy to use and simple to understand. The even offer an Unsubscribe option that keeps me GDPR compliant.
Cons: This tool should be exposed more to the General public. I happened to stumble accross it completely by accident.
Overall: GMass allows the author of the campaign to maintain focus on the content with standard features that overshadow their competitors. As I've mentioned previously in this review form, I've been in this industry for a number of years and have used many other Email software and services. They cost me THOUSANDS and have taken creative control away from me. GMass simply offers guidance, tips, and opportunities that can be used or not. It's also the most cost-effective as well as the most impactful with detailed analytic data that helps me alter my campaigns based on my customers. My Open rate is nearly 85% out of 1k target campaign.
Effortless, targeted leads by the masses

Pros: I love being able to enter my lead criteria (e.g.: marketing VPs, NYC area, pharma industry, 10-50 employees, etc.) and then rest assured knowing those are the leads I'm getting. Gmass allows you to enter each of them into customized drip campaigns with full control.
Cons: The only downside is the number of leads you can capture per day, but this is a LinkedIn API issue, not a Gmass issue. On average I've been able to extract about 600-800 leads per 24 hours. I guess I shouldn't be complaining.
Wish I knew about this sooner!

Likely Extremely
Likely
Pros: Easy set up, worked like a charm. Wish I know about it sooner
Cons: I wish bad emails went into a separate folder instead of my inbox
Overall: Was pretty good
Amazing Tool For Your Business

Likely Extremely
Likely
Pros: That it's a super easy to use and understand App that you can start using on the same day that you get it.
They help you with advice and tips along the way, while sending mass emails with Gmail in an organized way!
Cons: Not about this software, but I dislike the Gmail sending limits.
Respect this Gmail limits!
Overall: Overall I have a great experience using Gmass.
I use it for my business with my GSuite accounts, and it works great! I contact people in a personal way with a simple click!
Gmass is great!
Pros: It allows me to automate email camapigns to potential candidates or clients with ease. I can do it straight from my company gmail account.
Cons: It has a large learning curve to it. But they have a convenient blog section that covers most of the functions of the system.

Huge fan of GMASS

Pros: I love the ease of use, the fact that it's integrated into gmail, and that it helps automate work I used to have to do manually.
Cons: I wish it had a feature to autoscale the number of sends each day, whereas today I have to manually go in and edit the number.
GMass has helped me generate tens of thousands of dollars for myself and my clients.

Likely Extremely
Likely
Pros: I can reliably set it and forget it. Once the automated follow ups and schedule are set, it works like a charm. The sendgrid setup is easy and quick as well, which is helpful.
Cons: I don't like the inaccuracy of the open tracking, which is a known issue with iphone users. I don't like the price as a monthly fee, when I don't necessarily use it often enough for that. I don't like that sometimes my images have to be re-added if the draft has been sitting too long, and (at least last time I checked, this wasn't addressed in the FAQ)
Overall: extremely easy to create automated follow ups or just simply schedule an email to send at another time.

The service I've been needing my entire life...


Likely Extremely
Likely
Pros: The fact that hundreds of emails can be sent at once, all customized is the best part of Gmass. Up until now, I've had to send out either bulk generic emails or if customization was a must, I had to do them one at a time which took hours. But with this, I'm able to do that with a click of a button and move on to other things in my business.
Cons: I'm not a big fan of the fact that opens, bounces and replies are tracked using emails. Especially with the opens, it makes it extremely hard for me to track and make decisions based on open rates.
Overall: I do a lot of prospecting and engaging with my clients via email. This service allows me to do that more seamlessly, saving me time to spend on other aspects of my business.
GMass is a super convenient way to covertly email groups in a way that seems personal

Likely Extremely
Likely
Pros: I love that GMass syncs with Google Sheets and allows for for easy, automatic follow-ups. It does its job of keeping messages personal and customized without allowing the group to know that it's part of a group. Most of all, the plug-in works.
Cons: It's not the most elegantly designed plug-in; it's hard to remember, when you use it occasionally, how to insert conditional items (ie spintax notation);
Overall: it allows me to reach customers and prospects quickly and efficiently while still maintaining a personal connection in each email.

GMASS Makes Silent Auction Solicitation Easy


Likely Extremely
Likely
Pros: GMASS made my silent auction solicitation fast, efficient and effective. Also their instant response reports assisted me in cleaning up my email list, by purging those emails that were not able to be delivered and initiating efforts to get correct email addresses. Outstanding. I did get some blocks of emails and thought these were a problem with the site, but that wasnt the case. Because when I sent these notices as a regular email not as GMASS, they were still blocked.
Cons: I found nothing that I did not like about this application.
Overall: I wanted to send out a mass solicitation for our silent auction. GMASS made my life so much easier. Mahalo

GMass is a bad product!


Likely Extremely
Likely
Pros: No affiliate links in the footer of the mail telling everyone that I'm spying whether they're opening the mail or not!
Cons: I'm a one-person freelancer using the features very minimally. It gets the job done for me pretty well.
Overall: I can track opens and clicks of the mails I send. It tracks everytime the user opens the mail. This is valuable because if I notice someone opening the mail repeatedly I can reckon that they're highly interested in the contents of the mail. This is valuable for proposal mails.
Exceptionally Powerful for Low Investment

Likely Extremely
Likely
Pros: When trying to do our first big mailing campaign (nearly 30,000 recipients with almost 200,000 points of personalization), we were really overwhelmed with trying to figure out how we could possibly do this. Enter GMass Mail Merge - I honestly can't believe just easy it has been to use, and how informative the help articles are. With a bit of tweaking here and there, we've been able to create incredible mailers, and plan on using this for a long time to come.
Cons: Very little to dislike so far - seems incredibly robust for the price paid.

great for small (or large) mail merges


Likely Extremely
Likely
Pros: I love Gmass, especially for quick mail merges that only go to a few people. It's as easy as putting email addresses into the "to:" field and hitting the Gmass button.
Cons: No cons, other than I wish I could get a lifetime subscription. Seriously, it's very easy to use and saves me a lot of time each time I have to send the same message to multiple people.
Overall: Easy and quick mail merges.
Works great!

Likely Extremely
Likely
Pros: Saves hours of time, sends personalized emails including people's names, pulls directly from Google Sheets, assures delivery of emails, auto follow up feature kicks ass, affordable price, great customer service response time.
Cons: Blog isn't as easy to navigate, lots of posts have the same tags so searching by different categories isn't very helpful. Campaign reports and invoice requests aren't aesthetically pleasing. Annoying that emails set up as drafts can only be sent immediately instead of being scheduled. Annoying that emails can't be previewed until saved as drafts.
Overall: Here I was, dreading over the hundreds of emails I was going to manually personalize when a friend told me about GMASS. GMASS saved me dozens of hours of menial work by offering a service at a highly reasonable rate. I ended up sending a few thousand emails for a fundraiser. I am extremely happy with GMASS and recommend it to others interested in saving hours of their time.
Makes everything so easy


Likely Extremely
Likely
Pros: I love how simple it makes my cold outreach process. Before I would have to spend hours sending and following up on emails, but GMass makes everything so easy.
Cons: I have used GMass for a good amount of time and I don't have anything bad to say about it.
Overall: I absolutely love GMass! I recommend it to all of my friends and business partners.
I Loved This App

Likely Extremely
Likely
Pros: The ease of use.
The detailed blog.
The pricing is competitive.
Cons: The text heavy user interface. I think it could use a few more icons.
Overall: Gmass works straight out of the box. I have tried other apps, but none of them is as simple and straightforward as Gmass. The great thing about Gmass, is that, while keeping things quite simple, it also allows you the necessary level of complexity to have full control over several settings. They don't block you out of certain things. Plus the pricing is really competitive. It provides good bang for your buck. The help articles are also helpful. You can't go wrong with Gmass.
Time Saving & productive

Overall: greattt
Excellent transition tool when your building a more personalised mailing list


Likely Extremely
Likely
Pros: It's very competitive on price and starts out free with 50 emails per day! This is more than enough to find out if it is useful and to start building a personalised mailing list. It is also very simple to get started and by using spreadsheets becomes very powerful.
Cons: Nothing with the product but by using your main gmail / gSuite powered email you do run the risk of being restricted to spam if you aren't careful. Also be prepared to deal with failed messages when cleaning up your email lists.
Overall: Excellent tool to clean up mailing lists by offering a personalised message to recipients.
Works seamlessly with my prospecting


Likely Extremely
Likely
Pros: I love the follow up option. It is honestly a game changer, I'm able to schedule all my follow ups without constantly keeping track who opened my email or who didnt open my email.
Cons: Truthfully nothing yet, I've been using it for a month everyday so far and haven't found any issues with it.
Overall: Im able to send out personalized mass emails and it's saving me a TON of time. Working smarter and not harder with GMASS.

Gmass is the perfect emailing compliment-HIGHLY RECOMMEND


Likely Extremely
Likely
Pros: Gmass allows marketers and sales folks to automate a part of the emailing process without sacrificing the perceived quality of emails. I highly recommend. The interface takes a little learning (as it's embedded into gmail), but it's pretty intuitive for the complexity it's trying to pull off.
Cons: Not much. I like everything about it and don't have anything negative to say.
Overall: Fantastic.
Super simple extension with useful tools for mass emailing.


Likely Extremely
Likely
Pros: It lives in Gmail which makes it very convenient to use at the time you need it.
Also, I love the basic features included in the software such as reporting, auto follow-up for no replies. I'm most impressed by the simplicity of the software. It's got exactly what you need it without the bells and whistles.
The integration with Google Drive's spreadsheet is also seamless and I haven't seen it in other similar products.
Cons: I didn't like the automatic Gmass signature in the email at the time.
I've started using different mass mailing software so I'm not sure if that's still present.
Overall: I've used to outreach to potential customers.
A Great Product

Likely Extremely
Likely
Pros: Gmass was one of the best investments for my company. I would have to say the ROI is in the thousands. It really exceeded my expectations.
Cons: Nothing I can complain about. Im very impressed with its performance. And the only regret I have is that I didnt do it sooner.
Overall: Fantastic, a great product with a very short learning curve.

Likely
Pros: This cool add on integrates directly to your gmail, so all campaigns can be launched from your browser, no external SFs needed. Support for GSheets and personalization makes this a very powerful tool.

Clear and Intuitive


Likely Extremely
Likely
Pros: Oh, wow - a colleague told me about GMass when I was looking for a solution to email a batch of folks smaller than my main email list, but larger than I wanted to communicate with in one sitting. I'm not super-tech-savvy, but I learned everything I needed to know about how to send a mail-merge email to 450 recipients via a Google spreadsheet, with two customizable data points, in about 15 minutes. Clear and intuitive, I'd recommend GMASS to anyone looking to augment their marketing email needs!
Cons: The aesthetics could use a little work. But honestly, it's fine.
Overall: I needed to communicate with a medium-sized audience - GMass saved me hours!

Gmass is so easy

Likely Extremely
Likely
Pros: I recommend using GMASS for any email marketing campaign. It's so simple to use & pretty easy to use, I was up and running within minutes of downloading it to my gmail account.

Very easy to use

Likely
Pros: The easy instructions and functionatilty of the tool.

Great tool for mail merge with Gmail

Likely Extremely

Pros: It works very well and is easy to setup and use.
Cons: For my purposes, I did not need to receive so many email follow ups
Overall: For every project I work on, I ultimately need to send a mass email out to a group of people. Each one needs to have personalized information.

So glad I found this great tool to help me compose and send these very important emails.

GMass - Gmail bulk mailer


Likely Extremely
Likely
Pros: GMass worked just as advertised for a bulk mailing I required. Well done!
Cons: All worked well - no complaints or issues.
Overall: Needed quickly a bulk mailing tool for Gmail.
Useful Little Tool

Likely Extremely
Likely
Pros: I'm able to create an email sequence and send it to multiple customers
Cons: The follow up sequence has to be on the same email

Exactly what I was looking for


Likely Extremely
Likely
Pros: It is a very simple, yet powerful, piece of software. It does exactly what it advertises.
Cons: Nothing I can think of - for what I need to use it for, it is excellent.
Overall: So far so good. As mentioned - it is exactly what a was looking for to help me handle my bulk mailing needs
Incredibly powerful

Likely Extremely
Likely
Pros: A lot of features packed into this tool, yet very easy to use and incredible documentation. Highly recommend.
Cons: Can be a little bit intimidating at first - hence the need to spend time with the documentation.
Pros: Gmass has some amazing features, such as:
1) Easy to program and control auto follow ups. These follow ups go out based on lack of response from receiver and you can set date intervals for sending.
2) GMass links up with google sheets for easy access to emails lists. You can build a list within google sheets and then transfer contact information, and email scripts unique to each contact. It appears to each contact that you are sending the email just to them, but in actuality you are sending emails with one click.
3) Very few errors and well managed. I've only seen a few emails go out that were obviously not synced up correctly. Anytime this happens it's obviously not good, but its very infrequent.
Cons: GMass is almost 100% perfect at what it does, but here are a few drawbacks:
1) it takes a while to become familiar with the controls and layout as it's not super intuitive. The learning curve can be overwhelming for newbies
2) It tried to organize emails and drafts into folders to reduce clutter on gmail, but if you have GMass installed you will have a cluttered inbox. Hard to avoid unfortunately.
