Thunderbird is my preferred email client of choice. I use this app on every PC and on every operating system I use. It is stable, contains all the features you need, supports add-ons and also comes with a useful RSS reader. I am using Thunderbird for many years and never felt the need to look for an alternative.

Thunderbird 78 doesn't support classic XUL add-ons any more, but includes some of their features natively. E.g. on Windows you can minimize the app to the system tray.

Thunderbird 78.1.0 comes with the following changes.

What's new in Thunderbird 78.1.0

  • New: OpenPGP support is now feature complete. Improvements: new Key Wizard, online searching for OpenPGP keys, and more.
  • New: The preferences tab now has a search field
  • Changed: Dark background in message reader is now disabled
