, our flagship open-source email and productivity platform empowering more than 20 million people around the world. While part of the Mozilla portfolio of companies, MZLA operates independently in both identity and organizational structure from the Mozilla Foundation and Mozilla Corporation.

Everything we build at MZLA is open source, developed transparently and in collaboration with a global community of contributors. This open approach shapes not only our products but also how we work: collaboratively, inclusively, and with a shared commitment to building technology that puts users first. We believe privacy and productivity should coexist , and that people deserve powerful digital tools without surrendering control of their data.

MZLA is a small but growing team of 50+ people distributed across seven countries . As we evolve Thunderbird from a single application into a suite of privacy‑respecting productivity tools, we’re introducing new products and services that remain independent of big tech ecosystems . Our unique revenue model combines community donations that keep Thunderbird freely available with subscriptions for new cloud‑based services, allowing us to grow and innovate while remaining independent and true to our values.
