Labeling and filing in an easy, fast and productive way. Easily searching for all my information. Pros All the features are great, maybe because it is super intuitive (Thunderbird style). I have wanted to pay for it, because it had special features that have made my email handling efficient and productive. Cons I honestly don't see any missing function. Alternatives considered [Gmail](https://www.capterra.com/p/202338/Gmail/)[Thunderbird](https://www.capterra.com/p/230507/Thunderbird/)[Microsoft 365](https://www.capterra.com/p/227157/Microsoft-365/) Reason for choosing Postbox I wanted a native application that would work quickly and productively.

October 17, 2024 5.0 I am now a very old man, but I've been using POST BOX for years since version 3, I think! And still "going strong" ;-) It is old people friendly, any time! Pros Easy to use and very complete...No problem at all to check and read mail... Cons Nothing at all. The more I think about the less failures I find Alternatives considered [eM Client](https://www.capterra.com/p/160239/eM-Client/) Reason for choosing Postbox Because I have been knowing and using it for long! Review Source Sarah Jayne D. Marketing Manager Information Technology and Services Used the software for: 2+ years ### "Conventional scroll bars - yes, non disabled people can use them without the need for counselling " June 12, 2022 3.0 I think I have made my point, but other issues... The merging of Postbox v. 7 and Outlook 2019 would provide the ultimate e-mail management application. Once Postbox Inc. staff extricate their heads from the sand, they could have a much better product. Pros I really do like the smart folders, and the ease at which they can be created. Having e-mail addresses from our three domains, two businesses and personal e-mail, makes this a life saver, and something not possible in Oulook 2019. Cons As somebody who has cerebral palsy, the scroll bars implemented in v. 7 of Postbox slow me down, and are unnecessary. Suggesting that non-disabled people cannot use conventional scroll bars is insulting, and if I were non-disabled, I would be questioning Postbox Inc's low opinion of me and others like me. Encryption should be easier to setup, and not to be able to schedule a date and time for specific e-mails to be sent appears to be a glaring omission, as is the inability to insert a signature at the cursor. The lack of read receipt options is also a major let down, and somewhat surprising. Review Source LC Lynn C. Retired Homeopath Alternative Medicine Used the software for: 2+ years ### "Satisfaction Guarenteed" July 31, 2024 5.0 I feel very secure using Postbox. I appreciate the ability to save emails in folders of my choice. Pros User friendly Ability to search for an email or subject in various ways I can create as many folders as I want and create filters for ease of filing Cons nothing to complain about after many years of use. Alternatives considered [Gmail](https://www.capterra.com/p/202338/Gmail/) Reason for choosing Postbox The responses I got after researching Internet, user and forum reviews. Was using Google at the time Switched from [Gmail](https://www.capterra.com/p/202338/Gmail/) I wanted more security and options. I like not having to go online to access my emails Review Source GH Guy H. None Writing and Editing Used the software for: 2+ years ### "Postbox a good experience!" June 27, 2024 4.0 The email client stands out with its intuitive interface and powerful features designed to enhance productivity. Navigating through emails is a breeze, thanks to its clean layout and efficient organization tools. The customizable tagging and labeling options allow for seamless email management, making it easy to prioritize and sort messages. Postbox's advanced search functionality ensures that finding specific emails or attachments is quick and effortless. Pros flexibilty and easy to use, also the custom tags that you can add Cons Emails do not display .webp images, this is very annoying. I send a feature request to Postbox Switched from [iCloud](https://www.capterra.com/p/204717/iCloud/) Apple mail became way to slow and almost unusable Review Source BM Bridget M. Producer Broadcast Media Used the software for: Less than 6 months ### "Simplicity is the key!" August 25, 2023 5.0 I am able to work over multiple email boxes, be quick in my responses (as a quick reply option!) and i can change my email signatures with ease. I am really enjoying the program so far. Pros I like that it is very user-friendly, simple to use and does what I need. It does not go over the top on extra things that you don't actually need when sending and working on emails. No gimmicks, simple and easy. I can make changes to suit my needs very quickly, without having to navigate a whole load of items that are not required. The support is good, and there are videos if you get stuck. But for me, it is the simplicity of it all, that it is quick and easy, I can change the default theme with 1 click, and it only took a few minutes to set up how I wanted it. Cons It is yet to have a calendar added to it, but I can use others until that comes in. Also, it does not separate clearly how old emails are, it would be great to have a divider between each day's emails, just so it shows more clearly. Switched from [Microsoft Outlook](https://www.capterra.com/p/227138/Microsoft-Outlook/)[Gmail](https://www.capterra.com/p/202338/Gmail/) I do not like how Gmail works, it is just not for me, so I moved to Outlook and have used it for years, however, with my work, I have a lot of large emails, and Outlook stopped working as I filled my inbox. I tried multiple new programs, around 8 in total, all of them, I was having to change how I worked and used the program to fit with it, which was annoying. This program works how I want it to, so works with me, not against me. Review Source LF Laura F. Distinguished Service Professor Higher Education Used the software for: 2+ years ### "Overall good product but with a few annoyances" February 3, 2022 5.0 Overall, my experience has been positive. It would be nice to be able to request a feature and receive a response from Postbox staff as to whether there is any possibility of implementation. Pros Postbox is relatively easy to use. The overall interface and design are well-done, which contributes to ease of use. Postbox has powerful search features and searches are rapid, after initial indexing has occurred. The ability to quickly filter by contact name or by other message characteristics is also very nice. Displaying just the names of attachments and being able to quickly review them is a big plus. Cons The most annoying feature for me is that selecting a topic for a message will add that topic to the entire message conversation. Often I want to tag different emails in the conversation with a different topic tag but this isn't possible. I've used Postbox for many years, but as my number of saved emails has accumulated, I need to be able to categorize them individually so this "feature" is increasingly leading me to consider other email software options. Switched from [Thunderbird](https://www.capterra.com/p/230507/Thunderbird/) I switched most of my emails to Postbox from Thunderbird when development of Thunderbird was slowing down. I continue to have to use Outlook from work. Originally Postbox was far superior. Outlook has gradually been improving but is still more expensive. Review Source Chris B. Customer Support Manager Information Technology and Services Used the software for: 2+ years ### "My Go-To Email Software!" December 15, 2019 5.0 I have been using Postbox for the past several years and it has become my go-to desktop email client. It is able to handle my many emails that I get daily on my several email accounts, both work and personal. Pros Ease of use, available options, visual styles Cons There is nothing that I can think of that it doesn't do Switched from [Mailbird](https://www.capterra.com/p/160517/Mailbird/) Mailbird didn't have the features I needed built-in Review Source Johnny Ace S. Account Manager Health, Wellness and Fitness Used the software for: Less than 6 months ### "Streamlinec communications for the multi-preneur" December 26, 2019 5.0 As a user with multiple projects for multiple enterprises going at the same time, I found myself missing communications or misplacing threads because of the sheer volume. Postbox has helped me to better navigate the deluge of email communications that I receive, and to filter what is necessary to focus on now and what can be stored away. I appreciate the tagging and image search features especially. Pros The ability to combine all of my email inboxes intelligently, with deep search and filtering capabilities that help me to not miss anything from my various projects. Cons Would love to be able to extend these functionalities to my iOs devices Switched from [eM Client](https://www.capterra.com/p/160239/eM-Client/) The search function is much deeper in Postbox Review Source NM Neil M. Director Construction Used the software for: 6-12 months ### "Good email client" July 31, 2024 5.0 Pros Simple to use, great to separate work and personal emails Cons No support for Microsoft’s modern authentication methods, yet. Switched from [Thunderbird](https://www.capterra.com/p/230507/Thunderbird/) Separation of work and personal accounts Review Source KT Kaliko T. Online Educator E-Learning Used the software for: 2+ years ### "Highly Recommended" August 15, 2020 5.0 Postbox has allowed me to aggregate all of my email messaging into one place and keep my messages and attachments all organized in one easy-to-use and reliable local work area. I can't say enough, because I am truly indebted to the developers of Postbox for making such a great app and helping me organize my very busy messaging life and work/personal business for the past seven years. Pros Excellent management of my 35 inboxes. Yes, that's thirty five. But this app handles it with aplomb. And believe me when I say I have tried just about every email client and web app around (and continue to do so when new ones come out). But Postbox has stayed my first choice on my Mac for the last seven years. It's reliable, looks great in "dark mode", has great filters, lots of power "under the hood" for power users who want local email management (vs gmail online interface for example). Excellent search features (both inbox-specific and global), tagging (also automated via filters), and oh it's so smart! It knows if you intended to add an attachment but forgot to do it - it will remind you before sending, which is a nice touch! It has a timer when composing. Oh and it also has an "attachments" view which lists all attachments per inbox - a unique feature I love. I find the layout to be excellent and nicely configurable. Postbox Preferences are well laid out and plentiful. I could go on ... just get it and try it out! Cons The current version (7.0.25) I find confuses me with the "tabs" available in the interface to allow for multiple inboxes or folders to be open at the same time. I don't understand how or why they are sometimes automatically created. Also, the "from" address field lists all available email addresses for the accounts you are using, as expected. But the list is seemingly unsorted and random, so for only a couple of "from" addresses I am sure it's fine; but for me with my 35 possible options, it's hard to find the address I want to send from if I need to change it while composing an email. In neither case, however, are these small issues deal-breakers. Get this app and you will love it! Reason for choosing Postbox I chose Postbox over alternate products because it turned out to meet or exceed my expectations and what other apps were able to do for me. Also it looks great! Review Source HG Harald G. Owner Design Used the software for: 6-12 months ### "Best option!" November 15, 2019 4.0 In sum, I am happy with the purchase if you are a major user of mail, but do not want to spend much time on it. Beyond what you have to, and one has to sort, group and have a workflow beyond Apple mail and where Outlook gets too "hot" on notifications and integration. Would recommend it to anyone who needs Mail sotware, beyond using the smart phone for everyday use. Pros I like Postbox because it is clear, secure and gets the additions that I look for in a mail software. Appears as secure in relation to insecure mail, also has the opportunity to have several profiles separated as work and private, but not at the same time !. Gives me good control of my mail in a satisfactory way. Have either not started as far as I can see subscription, which I appreciate, one of the competitors has been uninstalled because of this. Is a full and good alternative to Mail Mac, for Window it does not seem as big and heavy as Outlook. Cons What I don't like are any restrictions in integrating with other apps. It can come from security, and it can come across as messy, what I have registered with a competitor. But being able to sync or have a calendar would be great. Alle doesn't use OmniFocus, there are others too. And of reasons I have mentioned. Failed to integrate Devonthink, nor spamsive. Difficult with tags, but there are at least tags;). The price may be high, but as long as there is no subscription, you have to pay something !. Reason for choosing Postbox I've already tried everyone else, so if the Postbox start to change too much on its formula. I have a problem. Review Source FM Frank M. Administrator Computer Networking Used the software for: 2+ years ### "Postbox for selfemployed users" August 12, 2021 5.0 I manage all my business and private mails. And that does Postbox very good. It is much better than Outlook and a little bit better than Mozilla Thunderbird in the usability. But the other two have the better groupware and collaboration features (with add-ons). Pros In Postbox I like how easy it is to manage a lot of mailboxes (to group them for example in "business" or "private"). A big advantage is a very good "3-pane-view" and the quick filters for "unread" or "with attachement" or VIP persons. Then it is very easy to forward received attachements in a new mail with this sidebar in the compose window where you can see the last received attachements. Cons For business use I miss two things really much: integration of CardDAV to use my contacts that are stored in my private Nextcloud. So at the moment I have in Postbox different contacts than on my smartphone and tablet. And I miss also the CalDAV integration with an internal calendar. Some years ago there was a calendar add-on. So it is difficult to save or accept invitations directly to a calendar. Maybe a task management would also be nice (also together with the Nextcloud server). Switched from [Thunderbird](https://www.capterra.com/p/230507/Thunderbird/) better mail handling and 3-pane-view Review Source PT Philipp T. Product Designer Design Used the software for: 1-2 years ### "The email app for power users." April 12, 2022 4.0 Pros I have been using Postbox on my Mac for over a year now and it is without a doubt one of the most powerful email clients out there. Since I am a privacy advocate I am using ProtonMail for my personal and professional email. ProtonMail is currently available as a web app, and for Android and iOS. That means there is no dedicated Mac App available. Most of the time, I am working on my emails on my Mac, therefore I decided to go on the hunt for a powerful email client to work through my open emails. Since ProtonMail uses end-to-end encryption there are very few email clients available that can be used with a ProtonMail account. One of them is Postbox. Postbox features a beautiful, clear, lucid, and modern interface. One of my favorite Postbox features are the power to group my accounts, view email in tabs, the search with advanced queries, and of course the quick bar to perform any kind of actions with just a few keystrokes. Cons Although Postbox is a lovely piece of software, I would say it is mainly aimed at people who are writing loads of emails, people who are power users. For casual email workflows you probably do not need all the features Postbox is offering, and therefore you might take a look at alternatives. But if you are on the hunt for a desktop client for your ProtonMail account you should definitely take a look at Postbox. Review Source NA Nawaf A. GM Retail Used the software for: 2+ years ### "My personnel take" August 14, 2020 4.0 Overall It would have got a full rating if it was not for the tech support being billable considering I am a licensed user, and the fact of not having the basic ability to export accounts on the fly to another machine or same machine for a clean OS install, atleast the option to backup imap accounts / settings not folders should be standard. Pros Very clean light software easy to install, used this on my mac as well as windows with minimal issues. I like the theme option with the software and the ability to organize accounts groups as well as folders etc easily on the fly. There are still many features I have yet to explore but the most part I like most is the stability of the software. Cons The export functions for existing email accounts regardless of it being POP or IMAP needs to become a standard feature, as I have plus 20+ email account and sometimes I tend to move from one computer to another the part of not being able to just click and export my existing settings is tedious. Another fair feature that one would ask for is for those who have a valid license then the tech support should at-least be free of charge and not billed per request. Review Source JR John R. CEO Marketing and Advertising Used the software for: I used a free trial ### "The exact tool I was looking for but didn't know existed" December 21, 2021 5.0 Pros The fact that I can add multiple email addresses to Postbox, as well as the way it manages those email accounts, meaning it does not turn into a mess like when I did it in Outlook Desktop before, plus Outlook crashed like crazy. I then moved email accounts to Gmail and that also comes with it's limits and I was not always sure that my emails were arriving. I have been looking for a tool like Postbox for the longest time and could not find it, until I saw someone mention it in a Facebook group post. I then searched it, found it, started on the trial, and purchased a few days later without waiting for the trial to finish. Cons No cons so far. Everything is working exactly as I want it to work. Review Source AB Arthur B. Business Owner Publishing Used the software for: 6-12 months ### "Postbox Works Best For Me" December 10, 2021 5.0 It is something that I can depend upon. My business relies heavily on email and I need to know I am receiving all my emails and am able to send without worry. Pros Works for me way better than any other I've used such as Outlook and Google. I like the layout and options. Cons That would be hard to say because I haven't noticed any "cons." Alternatives considered [Thunderbird](https://www.capterra.com/p/230507/Thunderbird/)[Opera](https://www.capterra.com/p/229024/Opera/) Reason for choosing Postbox I tested each and didn't like them.

Pros It has totally taken me away from my Outlook application. Cons Can't say I don't like anything about this product. So far, it has done everything that I want it to. Review Source AK Athar K. Attorney Law Practice Used the software for: 1-2 years ### "Excellent Cross-Platform Experience with Great Filing Features" November 23, 2019 5.0 Overall very good experience. Needs a few engagements but overall a great app that is always being developed. Pros I use a Mac and a PC and having an app that offers the same experience on both platforms is a huge plus. The biggest reason I like PostBox is that it allows for very quick, easy, and efficient filing of messages. (That was my biggest complaint with Airmail). I also like that they update and improve it continuously. Cons There isn’t much to dislike. I wish they still allowed plugins like MailHub which allow for a certain level of predictive filing features. While there are workarounds for some plugins like Todoist, there is no way to use a plugin for predictive filing. Reason for choosing Postbox Folder search and filing. Same Experience on every platform. Review Source ME Mick E. Owner Internet Used the software for: 6-12 months ### "Postbox mail client" November 3, 2022 5.0 No issues at all, in fact fixed issues I had with other clients. Pros Switched to Proton Mail and used with Thunderbird, emClient, Mailbird, all had issues. Discovered Postbox and worked perfectly with Proton. Not only that but blown away by just how good this client is, best of the best in my opinion. Cons Nothing except would like an 'Undo Send' option (delay for say 20 seconds), have submitted as a feature request... pretty pretty please! Reason for choosing Postbox As stated above, solved all my issues I had with the other clients and just works great, Proton Mail + Bridge in my case Switched from [Mailbird](https://www.capterra.com/p/160517/Mailbird/)[Microsoft Outlook](https://www.capterra.com/p/227138/Microsoft-Outlook/)[Thunderbird](https://www.capterra.com/p/230507/Thunderbird/) Issues with all other mail clients Review Source DD Drew D.

Pros I use the powerful shortcuts for sorting mail on a daily basis. The ability the seamlessly manage multiple e-mail and accounts in a unified inbox is something I absolutely need to have. Extremely quick comprehensive email searching saves me time on a regular basis. Finally the filtering options help keep me on top of all of my email messages. Cons At the moment I don't have much that I don't like. Reason for choosing Postbox None of the other products I looked at had the same set of features and performance.

Owner/Manager Arts and Crafts Used the software for: 2+ years ### "Awesome email program" November 24, 2019 5.0 My overall experience with Postbox has been very positive. I've been able to work with my multiple business emails as well as my personal emails, in a quick, efficient manner. Everything is handy and right on the screen and I don't have to dig around to respond to clients from different areas of my work. All and all, I've been super pleased with it's functionality as well as it's ease of use. And? It doesn't hurt my eyes to check and work in my email (GREAT BONUS!) It's a beautiful program. Pros Seriously, I have had nothing but great success with this software. It's super simple to set up, easy to navigate, has a great interface that's pleasing to work with.. and on top of all of that? Super affordable. I couldn't be happier. Cons I really haven't found anything to complain about. Review Source PD Per D. Designer Design Used the software for: Less than 6 months ### "A ton of well thought out features" January 27, 2021 5.0 With everything, it seems like a lot of thought was put into. And almost everytime I think, it would be awesome if … – chances are, I already can. I spent years trying to find an email app that didn't suck, I even tried out an earlier version of Postbox and was not particularly inspired. Lately, I came across the app again and decided to give it another go, and it seems my quest has come to a happy end. Pros I am amazed by the abundance of features and the ease of use of Postbox. The focus pane is a lot of help. I could not see the use for a Home button, until I figured out using two filters and a search term simultaneously (something like flagged mails from with in archive of ) could lead you way down into the depths of your mailboxes. Cons Everything I found Postbox to be lacking so far are just nice-to-have features on top of quite a few already really good ones. For instance, the Cloud File Sharing built right into the app is an incredibly useful feature, but it only covers box, Dropbox and OneDrive. I need a Nextcloud option. Review Source Harmen R.

It is now my main email client on Mac and Windows 10. Pros Intuitive to set up Easy to use Adaptable to my needs Great design Cons Windows version not as fully featured as on the Mac, but that hopefully is a matter of time before they catch up Reason for choosing Postbox Clean design. Best of the alternatives to Mac Mail and Windows Outlook. Review Source Similar Products Featured
