Thunderbird’s mission is to give you the best privacy-respecting, customizable email experience possible. Free for everyone to install and enjoy! Maintaining expensive servers, fixing bugs, developing new features, and hiring talented engineers are crucial for this mission.

If you get value from using Thunderbird, please help support it. We can’t do this without you.
