— Thunderbird

Send/receive emails with a privacy protecting host based in Germany and the latest mail standards like JMAP. Choose a Thundermail domain or bring your own. Look no further to power the open source email app you love.

Instead of exchanging multiple messages to schedule a meeting, select your availability and let Appointment handle the rest. Appointment is powered by open standards and compatible with Google Calendar. You can now schedule like a pro.

Share large files with end-to-end encryption and fewer limits. Send provides a natural file attachment experience in Thunderbird Desktop and is compatible with any recipient’s inbox. Know your attachments will arrive safe and secure.

Made for You

Open Source

The technology powering Thunderbird Pro is freely licensed and open source, offering you transparency, security, and freedom. By subscribing you fund the development of our other open source tools which remain free-of-charge, free-of-ads, and free-of-data-harvesting.

User Focused

Thunderbird Pro is part of our mission to help you communicate, collaborate, and connect freely. The Thunderbird Desktop and Mobile apps remain the core of how we offer these benefits and your subscription helps us make them even better.

Freedom Driven

Money isn't our mission, it is the means to bring freedom and productivity to as many people as possible. Freely licensed software, open source code, and open standards liberate you and remain at the heart of Thunderbird.
