Since 2003, Thunderbird's mission has been to offer a powerful and customizable communication experience that respects your time, your data, and your privacy. Free for everyone!

Accomplishing that mission means keeping Thunderbird secure, maintaining complex server infrastructure, updating old code, fixing bugs, and developing new features. These activities are expensive - requiring talented software engineers and robust infrastructure.

So today we’re asking you to help us out. If you get value from using Thunderbird, please consider giving a donation to support it!
