Full Featured Mail App and More **Rating:** 4.5/5.0 stars **Reviewed by:** Scott F. | Principal, Small-Business (50 or fewer emp.) **Reviewed Date:** April 25, 2023 **What do you like best about Postbox?** Postbox has a MASSIVE amount of features for a mailing app, so many that I would easily say it rivals Outlook in its abilities to act as not just a mail program but a full contact manager. GMail users especially (like myself) will enjoy how familiar the interface is, and how many of GMail's Labs features are built right into Postbox. They also have updates fast and frequent. **What do you dislike about Postbox?** Two things stick out in the dislike column. First, even though this program works on both Max and PC, much of the marketing is geared towards the Mac environment rather than PC, which can turn people off. Also, on the function side, as a GMail user I have many, many tags I use to organize mail, and the Postbox program doesn't allow you to SEARCH those tabs while trying to mark a piece of mail before archiving it, which can be tedious. **What problems is Postbox solving and how is that benefiting you?** Postbox allows me quick online and offline access to ALL my email accounts in one central location without having to change programs, browser tabs, and without having to log in and out of multiple web accounts. ### 2. Lots of promise, but underdelivers **Rating:** 3.0/5.0 stars **Reviewed by:** Randall H. | Distinguished Software Architect, Mid-Market (51-1000 emp.) **Reviewed Date:** September 01, 2022 **What do you like best about Postbox?** Beautiful UI, with some great searching and indexing features. IF you want offline access to email with some high-powered search & sort features, it's a great solution. **What do you dislike about Postbox?** Even though PostBox is just Thunderbird with some paid-polish, the latest version removed some of the best features like Extensions. Given how slow the developers release updates, it makes it somewhat of a no-go if you want things like Contacts Sync with Google, or integrations with anything special like SalesForce or other tools. Plus, their Google integration is just confusing and weird all around. The way they try to mix Folders & Labels, and having multiple Junk Mail systems that don't seem to work properly in their default configuration (Google's anti-spam and PostBox's built-in spam) just result in a muddy inbox. **What problems is Postbox solving and how is that benefiting you?** Faster access to specific emails buried in my inbox, with better sorting features that I can manage with keyboard shortcuts to maintain an Inbox Zero. Unfortunately, I'm probably going to abandon it because it just doesn't integrate with my company's email (Google). ### 3. A Must Have If You Have Lots of Mailboxes to Manage **Rating:** 5.0/5.0 stars **Reviewed by:** Ice X. | Managing Director, Small-Business (50 or fewer emp.) **Reviewed Date:** September 28, 2021 **What do you like best about Postbox?** It's easy to add mailboxes that you manage, and the interface is clean! **What do you dislike about Postbox?** It's a little pricey for a mailbox manager; the company should offer a simple solution to sync mailboxes and settings across all devices. It does not support Android or iOS. **Recommendations to others considering Postbox:** This app doesn't get updated very often. However, with what it currently offers, I'm not seeing any features that are lacking. It would be great if they bring out Android or iOS support later down the road, as well as sync settings and mailboxes across all devices. If that's what you need, it may be a deal-breaker. Otherwise, Postbox is an overall pleasant software to use. **What problems is Postbox solving and how is that benefiting you?** I want a no-ad solution that offers offline access to all of my e-mails. The interface is clean, and that it allows me to view only attachments, which is nice. ### 4. Email manager **Rating:** 4.0/5.0 stars **Reviewed by:** Raymundo M. | Security Engineer and Development, Mid-Market (51-1000 emp.) **Reviewed Date:** October 12, 2021 **What do you like best about Postbox?** I like it because I have no limits to synchronize or connect emails from different services, I have emails from Gamil and shared Hosting and I control everything from one place. Themes and graphic interface perfect for work, interpret HTML to send personalized messages. **What do you dislike about Postbox?** I do not like that I do not have a version for Linux, perfect tar but that great detail is missing to be able to work on my phone, Windows and Linux at the same time synchronizing everything. **Recommendations to others considering Postbox:** Synchronize emails without limits, work organized from a single professional platform with hundreds of special functions. **What problems is Postbox solving and how is that benefiting you?** The main thing is comfort and send professional email without using different platforms, with Postbox I send and receive emails, manage my contacts and direct chat. ### 5. Best mail app so far **Rating:** 4.0/5.0 stars **Reviewed by:** Jessica D. R. | Virtual Assistant, Small-Business (50 or fewer emp.) **Reviewed Date:** December 02, 2021 **What do you like best about Postbox?** Like that it's a unified inbox but able to separate into folders. Like that you can change and customize themes. **What do you dislike about Postbox?** Dislike that some options aren't intuitive or have too many clicks (like being able to filter by unread). **What problems is Postbox solving and how is that benefiting you?** Keeping multiple personal and business emails together but separate. ### 6. Half-baked. (Could have been really great). **Rating:** 0.0/5.0 stars **Reviewed by:** Erich F. | Co-Founder, Creative lead, Small-Business (50 or fewer emp.) **Reviewed Date:** October 31, 2021 **What do you like best about Postbox?** It's clean, streamlined and the desktop app is really good. But it has a MAJOR flaw. No mobile companion app. **What do you dislike about Postbox?** It’s the 21st century. 70% + of users check their email via mobile devices. And yet… NO MOBILE COMPANION APP? **What problems is Postbox solving and how is that benefiting you?** I need a good email app for Gmail. There's no benefit to Postbox since there's no mobile companion app. ### 7. Terrible support. Buggy software, almost no updates. **Rating:** 0.0/5.0 stars **Reviewed by:** Khiman L. | Support Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** May 07, 2021 **What do you like best about Postbox?** It looks nice, it's slow but it works most of the time. **What do you dislike about Postbox?** Lots of little, very annoying bugs. Release cycle is super long, and there's barely anything new each time except themes. Yes, they try to sell you themes for an email client... You buy the software, but they charge you 8$ per support request ! Basically you buy a supposedly production ready software, and then when things go wrong, you're no your own unless you pay up, and even then, your issue probably won't get fixed for a few more months. **What problems is Postbox solving and how is that benefiting you?** Nothing more than what an email client is supposed to do really. ### 8. Best Email App to Keep Inbox Clean (quickly!) **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.) **Reviewed Date:** January 01, 2021 **What do you like best about Postbox?** I've tried them all, Postbox is not the most beautiful but it is the most efficient. I can move mail around in a flash, find it even quicker. I can sort it every which way and there are so many ways to categorize and find it that I can take my inbox from 2000 messages to 100 quickly. This is extremely important for someone that gets a huge amount of mail. **What do you dislike about Postbox?** The customization of the Themes could be a little more intuitive but that is being picky. It could also use Exchange compatibility. **Recommendations to others considering Postbox:** Try it out and give it a little time to get used to it. When you change to another product to get a lot of flashy icons and can't find your mail, you'll be back. **What problems is Postbox solving and how is that benefiting you?** As I mentioned locating and moving mail is the most important function of any email app in my opinion and I have solved it with Postbox. ### 9. Postbox—pretty, but cumbersome... **Rating:** 1.0/5.0 stars **Reviewed by:** Ashley C. | Media and Web Designer, Small-Business (50 or fewer emp.) **Reviewed Date:** July 22, 2020 **What do you like best about Postbox?** What I like best is how clean and well-organized the user interface is. I have tried many email clients (probably all the majors email apps on Mac), but this one feels the cleanest to me. **What do you dislike about Postbox?** Searching and indexing is a little slow. Other mail clients I've tried were lightning-fast by comparison. Formatting emails was inconsistent. (No markdown support, for whatever that's worth.) When going through a list of emails (inbox, folders), there is no way to view at a glance any labels assigned.This was a big dealbreaker for me. (I've switched to an ultra powerful, minimialist email client that is nothing pretty to look at, but more than makes up for it in functionality.) Also, Postbox charges its users a fee for any technical support (even after you have already purchased the software). The support I did receive was less than great. (definitely inferior to the free support I've gotten from other companies.) **Recommendations to others considering Postbox:** Maybe keep looking? I've recently found a much better solution for me. It's in the same price range—not going to win any beauty contests, but functionality and speed are top-notch. **What problems is Postbox solving and how is that benefiting you?** Postbox hasn't really solved any problems for me—it handles multiple email accounts like all the other clients I've tried. Haven't found any benefits that outweigh the searching/indexing lag. ### 10. It's akin to Google shipping you a supercomputer but neglecting to include instructions **Rating:** 1.5/5.0 stars **Reviewed by:** Anita T. | Small-Business (50 or fewer emp.) **Reviewed Date:** October 28, 2019 **What do you like best about Postbox?** I love the visual interface, themes, add ins and the templates. It is a fairly powerful software and has a lot of useful features as tagging, goal setting, in-line text detection and a decent filter. **What do you dislike about Postbox?** No where to get help or learn. Postbox only has a couple general tutorials/help questions for some basic issues. Their helpdesk charges $8 per request. Hence if something goes wrong - which is common in any sort of innovative software, you are trying to troubleshoot things without any guidance. A lot of their features are powerful but not intuitive like html placeholders, adding templates, changing goals, etc. I don't mind the instability or the learning curve and I'm willing to spend time troubleshooting. However I can't do that without any sort of guidance. **What problems is Postbox solving and how is that benefiting you?** It was suppose to help my organize and control my inbox. But no help kinda cancels out any of that. :( ## Postbox Discussions - [How do I fix it the saving issue for sent messages?
