MailMate – The Best Third-Party Email Client for Power Users

MailMate is a smart third-party email app for Mac users.

MailMate is not the most widespread, the cheapest, or the greatest looking email client, but I also have no aspiration to MailMate ever being any of these. Instead, MailMate aspires to be the most powerful, the most flexible, the most efficient, the most standards-compliant, and the most secure email client.

MailMate features:

  • Multiple Accounts (A universal app supports most servers)

  • Full Offline Access (Almost all functions are available in offline mode. Changes done while offline are automatically synchronized when going online)

  • Notifications (Multiple dock counters, multiple menu bar counters, and notifications are optionally displayed)

  • Dynamic Signatures (The default signature and placement (top/bottom) of the signature in a new message is automatically derived from emails to the same recipient. You can use a shortcut to select a different signature.)

One of the main benefits of MailMate is having a small user base. So, you can expect a reply if you have any problems or requests.

MailMate is one of the most expensive email clients we reviewed and is available for $50 from the developer’s website. But you can try the fully functional 30-day trial (active use).  What concerning the price, MailMate is not for everyone – in fact, it’s not for most people. The interface is very functional, but also pretty boring. If looks are important to you, you won’t like MailMate. But, if you’re looking for the most powerful and most standards-compliant email client available, you can try this smart email client.
