About Us

What is Thunderbird? Software made to make email easier.

Thunderbird is a free and open source email, newsfeed, chat, and calendaring client, that’s easy to set up and customize. One of the core principles of Thunderbird is the use and promotion of open standards - this focus is a rejection of our world of closed platforms and services that can’t communicate with each other. We want our users to have freedom and choice in how they communicate.

Nortzuk garen We are a community making communication free and open.

Our Mission

Email has been and continues to be the fundamental communication tool and a significant driver of freedoms on the Internet. But it is also threatened by new non-standards-based, closed and centralized messaging platforms. To prevent this erosion, the public deserves an alternative that is secure and reliable, while protecting our privacy, enhancing our productivity and serving as a platform for current and future forms of messaging.

Thunderbird facilitates cross platform, decentralized, open-standard communication, which puts the user in control of their data and workflow. We aspire to offer an interoperable and extensible open-source platform for messaging and managing personal information, such as email, contacts, and appointments.
