Not just in 2023, but decades into the future! ( Note: user donations represent more than 99.9% of our annual revenue.) Our 2022 donation income was a bright, assertive sign that you also believe in that mission, and you also want to see Thunderbird thriving. Last year, our mighty donor base – representing approximately 300,000 daily users – contributed a total of $6,442,704 in donations to the Thunderbird project. And to do all of this transparently, guided by the values of free and open source software. And to expand the Thunderbird experience to Android and iOS. To craft an experience that boosts your productivity, compliments your daily workflow, and meets your customization needs. To build professional software that puts your privacy first. Our mission is to build the best email client and personal information manager available. Then, just last May, we happily reported that Thunderbird’s financial outlook was steadily improving: our 2021 income had increased by 21% over 2020, and by more than 100% over 2018.īut we are not content merely surviving. Our dedicated core team, passionate community of users, and generous donors kept Thunderbird alive during some difficult times.

A few years ago, Thunderbird was in survival mode.
