About Postbox

Postbox is a fully-featured email app designed to provide users with access to all of their email accounts in a single interface. The app supports any IMAP or POP email account, including Gmail, Outlook, Yahoo, AOL, iCloud, Fastmail, ProtonMail, and more. Users can install Postbox on Windows and MacOS devices.

Postbox allows users to group their accounts to keep personal and work emails separate. Go-to folders can be added to the Favorites Bar for quick access, and quick filters let users organize emails automatically. The search includes advanced query capabilities, so emails can be found based on their date range, subject, sender, or other attributes.

Postbox is offered as a one-time purchase with no monthly or annual subscriptions, and licenses are per-user so can be used across multiple devices. Support is provided via a knowledge base, video tutorials and help desk.

Smooth desktop email client

Overall, Postbox is great for my personal email, as I've described above. My only major negative is that I cannot use it on Microsoft Exchange--that is, the only negative is that they don't allow me to use it even more!

Pros:

I'm a big fan of desktop email clients, rather than web clients, mainly because I can do a lot of email work even when I'm offline. Probably my favourite aspect of Postbox is the keyboard shortcuts. They are well thought out and so make my email use smooth--I can easily do so many common tasks with just one key click, such as moving messages to folders. In addition, there are so many tiny details that are almost invisible yet work so smoothly--I barely notice them until I work with other clients like Outlook. For example, when I delete messages, even if they have not yet been read, they are automatically marked as read when deleted so that I don't have to do the two steps of marking a message as read and then deleting it.

Cons:

My big negative is that Postbox does not provide native support for Microsoft Exchange--it only provides IMAP. This is a deal-breaker. First, IMAP is not a full replacement for Microsoft Exchange, so there were so many little things that just didn't work right, even after I carefully followed the instructions on Postbox's dedicated page to customize settings to try to work around those issues. Then, to make things worse, my employer blocked IMAP on its Outlook accounts, so I cannot use Postbox at all any longer for my work email account. I now use Postbox only for my personal accounts and then Outlook for my work account. I've already requested Postbox to add support for Microsoft Exchange, but they said there was insufficient demand for that feature. That is always a very dubious reason for not adding features--obviously, there must be some business users who would have the demand for Exchange support but then don't even bother with Postbox once they find that it is missing!

Pros:

I thought the download was just a generic email manager, but when I started to configure it, I realized that I'm not a technician and don't usually work with these kinds of things. I just have too many emails to manage. To my surprise, after 15 minutes of following the site's instructions, everything was done. All my emails were separated into folders with auto filters. I didn't encounter any difficulties, so I gladly paid for it and supported the developers.

Cons:

"Don't have AI support. The interface is a little confusing in the beginning, but it is customizable."

Reasons for switching to Postbox

"Spark is expensive, good, but very hard to use. The outlook is good, but I don't like how difficult it is to use and configure. Both don't have half of these options."

Only a limited version of Thunderbird with better design

Until version 5, the mail client was still worth its money. Today with version 7 I wouldn't buy it again because I get Thunderbird for free which is much more customizable thanks to the support of extensions. In addition, I noticed that the Thunderbird client on which the software is based is certainly not up to date because I get for Thunderbird here much more often updates which also affect the security.

Pros:

The design is currently the only positive thing I noticed about the software. Otherwise there are not really many positive things about this mail client.

Cons:

It is not possible to use extensions. No external spam filters possible. Some of the features like "preferred topics" do not work as expected. The folder management is more than cumbersome.

Pros:

Postbox combines the core features I need for an email app with an excellent support team. Management of multiple inboxes into both single and shared views makes it easy to manage my email, and there are several automation tools built-in.

Cons:

I keep asking them to integrate Grammarly. That's the one thing I need to make me completely happy with Postbox.

Reasons for choosing Postbox

I bought and used several apps at the time. Post box just consistently offered the best mix of tools and features and made using email the most productive out of them all now, if they would add Grammarly integration.

Reasons for switching to Postbox

There were too many things that outlook just over-complicated and thus did poorly.

A true email client

I have used Postbox since its first release. I have used it on both MAC and Windows OS and have always found it easy to use. The major plus for me is how easy it is to find an attachment and the way I can link to new emails. The program is built to be intuitive which means the hard work is always done for you. Every upgrade has left you with the same UI so you never had to re-learn how to use it. I currently store ten years of email on it so about 26,000 and have never had a problem.

Pros:

Postbox is very easy to use. I am sure it has more features that I haven't found yet. I replaced Outlook with Postbox and I am so happy I did. It is easy to use and has so many themes and features. So user friendly and didn't cost an arm and a leg to purchase.

Cons:

So far I really haven't found that many things I don't like about the software. I still need to work with it a bit more. Perhaps more items in the tool bar (eg.) Priority options in sending mail.

Reasons for switching to Postbox

I was tired of the program disappearing all my emails and then re entering them for no reason while I was checking my emails. The big lack of functions and features the cumbersomeness of it. The cost of it was very high and if you didn't upgrade your system it was not upgraded and you lost quality.
