If you want to encrypt your email, Thunderbird is one of the few clients that supports GPG/PGP encryption. This email client is also powerful enough for power users. Thunderbird makes it easy to hit the ground running if this is your first time using an dedicated email software. The setup experience takes the complication out of setting up a desktop email client and usually guesses the correct settings using only your email address and password. It has relatively large name recognition.

Thunderbird comes with many of the same advantages as Firefox.

Thunderbird is the most popular Linux mail client, and for good reason. Thunderbird comes from Mozilla, the non-profit behind Firefox.
