Help Keep Thunderbird Alive

What happened

Thunderbird has quietly put out an appeal asking users to chip in. It has been reported that less than 3% of Thunderbird’s user base currently funds the project, and the team says they don’t run ads, sell data, or take corporate backing. The message is simple and stark: Thunderbird’s privacy-first, customizable email client is being kept afloat almost entirely by voluntary contributions.

The ask

Thunderbird’s note lists the usual suspects: expensive servers, bug fixes, new features, and paid engineers — all of which cost money. It has been reported that the donation widget uses Fundraise Up, and that “your browser or an extension might be blocking our donation platform,” so the team recommends trying a different browser or temporarily disabling extensions if the page won’t load. Plain speaking: if you get value from Thunderbird, they say, now’s the time to give back.

Why it matters

Why should you care? Because independent, privacy-respecting alternatives are getting rarer as big tech gobbles up inboxes and ad dollars. Want Thunderbird to stick around as a free, no-tracking, no-ads option? That’s the emotional core of the appeal: the project isn’t just code, it’s a small public good that could wither without broad-based support. It’s a familiar refrain in the open-source world — useful things don’t fund themselves.

How to help

If you use Thunderbird and can spare a few dollars, the team asks you to donate via their update page (the one with the Fundraise Up widget). If the form won’t appear, try another browser or disable extensions as suggested. Small contributions from many users can change the math — and keep a decades-old email client from becoming a fond memory.
