Postbox Review



Postbox is one of the oldest alternative email clients for Mac and Windows out there, once characterized by an outdated user interface. A general UI overhaul has considerably improved Postbox usability, making it a noteworthy choice. Postbox offers a few more features than Airmail, a great email client competitor for Mac indeed. The client focuses more than ever on a more efficient email management thanks to functionalities like “account groups” able to blend or separate personal and work email accounts.

Another big plus point is the tab support: you can work on your emails like you do in your web browser, managing specific messages on different tabs. An innovative focus pane offers real-time filters instantly to take a look at unread emails, or on reminders, subscriptions and so on. Custom tags let you arrange your works in topics. Pre-Made Responses is another one of the best features provided by Postbox: you can reuse the same text you often send, saving your time. If you need to save more time, you can take advantage of the Postbox time tracker feature that lets you know how long it takes to compose a message.

No more sending errors: a domain fencing tool prevents you from sending an email from a wrong account. But there’s more: the client helps you target your message by contact. Thanks to a powerful attachments search capabilities, Postbox allows you find and use images and files in your mail, even while you’re composing a new email. Talking about integrations, Postbox works arm in arm with Dropbox, One Drive and Box. It works with best email providers including Gmail, Yahoo, AOL, and iCloud, supporting also POP3, IMAP, and SMTP protocols.

Postbox also shows little flaws: sometimes the interface is cumbersome, the searching icon is still non-retina, and the software lacks native Exchange support. Postbox pricing is reasonable: $15 after a 30-day free trial.


Postbox is an excellent third-party email client for Mac users thanks to well-thought-out and well-implemented features.
