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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

Postbox has handled my mail for 5+ years. It still does POP Mail, which I prefer over IMAP. I don't think I've lost any email messages. Review collected by and hosted on G2.com.

Numerous stability issues. After the app has been running for a while on my Mac, things start behaving unreliably:

Undo deleting or moving messages stops working, leaving a weird blank row where the message was in the list.

Sometimes, 'Delete' doesn't immediately delete a message and takes 10s to a minute.

In the past, the indicators for the number of unread messages would go out of sync: The one on the Dock icon vs the unread messages indicator next to my inbox. I'm not sure yet if this new version has fixed that problem.

For the last 2 upgrades from the prior major version, content whitelists have not been migrated, forcing users to re-whitelist scores of email addresses all over again. When I asked about this, they basically said it was too hard to implement.

I get pauses and busy cursors more often that I'd like. Sometimes, when I click on a message to file it, I'll have to wait 3 to 5 seconds while Postbox thinks about it. Review collected by and hosted on G2.com.

Version 7 arrived and I have a big smile on my face as I realise that I have bought a lifetime upgrade a while ago! Hands down this is the best email client out there!

I used to use Outlook, but now that feels vile to use compared to this client obviously designed by people that use email! I file my emails and the quick keys are now second nature to me, hit v then type the first three characters and boom my email is filed! Love it! Review collected by and hosted on G2.com.

The only addition I'd like is something closer to making emails a to do like in Outlook, that remains the only useful feature that outlook has that postbox doesn't! Review collected by and hosted on G2.com.

Every useful thing you can do with Outlook you can do with Postbox. It syncs with gmail perfectly -set your fonts-signature-add many accounts. It is awesome. Review collected by and hosted on G2.com.

Where and how it saves your emails takes some getting used to but you can back them up. Review collected by and hosted on G2.com.

I like the interface and ease of use I know this is not the latest design or do not attract much users like current market is moving forward to nice looking interface but i am ok with that old kinda look Easy to use on day to day basis. Review collected by and hosted on G2.com.

I would prefer to have a little more customization in the appearance of PostBox - it's a minor 'dislike', and by no way will it influence my decision to continue using, but having more customization and 'add on' features would be much appreciated Most importantly PGP Encryption o Decryption ability which was one of unique feature in postbox in last versions. But not the ones I sent him Review collected by and hosted on G2.com.

I like that Postbox is simple and provides basic email needs for my business. Review collected by and hosted on G2.com.

I dislike that Postbox does not have customer service accessible via phone. They only provide email service back and forth. Review collected by and hosted on G2.com.

I feel that it has a nice interface. Though it is based on the same Mozilla framework as Thunderbird, I think that it has as more streamlined "look and feel" and that it is easier to navigate than Thunderbird. Review collected by and hosted on G2.com.

It does not have as many addons, and the user has less opportunity for customization. It also has a strange glitch with the way it handles emails from WordPress blogs. I subscribe to several WordPress blogs, and Postbox continually merges them in weird ways. For instance, I subscribe to a blog called deadconfederates and another called the Eastman Online Genealogy Newsletter (EOGN). In Postbox when I get an email from deadconfederates it usually shows up with a subject line indicating that it's from EOGN. I have to open it to find out it's from deadconfederates. The same kind of mix up occurs with other WordPress blogs that I subscribe to. I offer this as but one example. This behavior does NOT happen with EmClient, Outlook, Claws Mail, etc. I contacted Postbox support about this issue. They refused to admit that it must be a glitch in their program. They said it was something about my installation. However, this is patently untrue since the same behavior with Postbox occurred on multiple computers running Postbox and with both Windows and Mac operating systems. They asked me to go through all kinds of things to test my system. I refused because it was clear that this was (and still is) a glitch in the way their program deals with incoming WordPress blog emails. The arrogance of their support folks really turned me off. If you don't subscribe to any WordPress blogs this would be a non-issue for you. Review collected by and hosted on G2.com.

I like the interface and ease of use. I know this is not the latest design or do not attract much users like current market is moving forward to nice looking interface but i am ok with that old kinda look. When macos new update came out postbox was already being updated and with the latest release of macos i was able to use it right away on updated operating system including new macos dark theme features. Postbox looks awesome in dark mode and does not matter which ever theme version i use it work flawlessly in all modes.

Postbox Company have done a great job since they released latest version.

Right now i do not find any issues postbox and i love the way postbox sync emails instantly. Review collected by and hosted on G2.com.

Sometimes use too much memory.

Postbox 6 do not have 3rd party plugins feature which is good for security but removing plugins for security also removed many features. Most importantly PGP Encryption / Decryption ability which was one of unique feature in postbox in last versions. Review collected by and hosted on G2.com.

Message filtering, organization, topics and color-coding feature, favorite addresses feature, tabs. Review collected by and hosted on G2.com.

I don't think they put enough thought into the power user that receives mail for multiple POP3 accounts through one POP3 server and then when the user no longer owns one of the domains they want to turn off the receiving of that particular POP3 account BUT not lose the mail he's received over the year. UGH! Very, very frustrating. Review collected by and hosted on G2.com.

It's extremely user-friendly and essential mimics Outlook, which I was accustomed to using on my PC. It keeps track of email threads, without doing it in a confusing way (such as how Gmail does it when using an internet browser). Review collected by and hosted on G2.com.

There is honestly not much I dislike. It was hard to find certain things, such as how to make emails "high-importance", but our IT team was able to help me out with that. Review collected by and hosted on G2.com.
