CEO of MZLA (the Mozilla entity that develops Thunderbird). One point of clarification, we don't get money from any source but our donors. After years of funding issues, MZLA was created by the Mozilla Foundation and the Thunderbird Council (our community governance body), to provide a legal/financial home for Thunderbird. Launching Thundermail this year (an email service) which we hope to help provide even more funds for development, beyond just donations. Also serving a user need (lots of our users ask us to help them get off Gmail). Lots of interest in how the money is spent - answer: mostly on devs, landed Exchange support recently (big for a lot of MS users), working on Graph support as well, JMAP after that. Updating the calendar (primarily UX/UI there), continuing to improve our Android app, working on a native iOS app and the aforementioned Thundermail service. We publish yearly reports and will publish one again this year detailing all this. Here is a 2025 recap: https://blog.thunderbird.net/2025/12/thunderbird-2025-review-building-stronger-for-the-future/ https://blog.thunderbird.net/2025/12/thunderbird-2025-review... But the blog has a ton of updates across the different efforts: https://blog.thunderbird.net https://blog.thunderbird.net Happy to answer questions and we are an open source project so feel free to reach out to us and engage if you really want to see how the sausage is made! *Edit: More context on what Thunderbird Council is*

With "Graph support" you mean "Microsoft Graph API"?
- ryanleesipes 6mo ago
  That's right. We've long had Microsoft account users across Exchange, Office365 and Outlook.com complain about having issues using Thunderbird. So we're trying to account for all protocols from MS.

Thundermail is a great idea! I'd be more than happy to switch over assuming the migration path from say Gmail, Fastmail, etc was easy enough, and it supported custom domains.
- ternaryoperator 6mo ago
  I can see switching from gmail, but it would have to be really compelling to get me to switch from Fastmail.
  - ryanleesipes 6mo ago
    What would get you to switch from Fastmail?
    - richardfey 6mo ago
      Probably JMAP support.
      - ryanleesipes 6mo ago
        Already a part of the offering. :)
    - Multicomp 6mo ago
      JMAP is a bonus (other fastmail user here) bjt if I can do custom sieve rules and or unlimited aliases created on demand at (somestring)@customdomainiown.com thst I can then use the sieve rules to put into a folder of the same name as that email address, I would rather give my money to support Thunderbird. Fastmail is fine and all but they are in australia so they live on spyware island and they dont have good native clients in the works like thunderbird does.
      - ryanleesipes 6mo ago
        Unlimited aliases at custom domains are a part of the offering. Technically, Thundermail supports sieve rules, we do need to come up with UX to expose it to users for management.

You could convince me to switch from gmail but I'm not sure I would switch from Proton to thundermail.
- ryanleesipes 6mo ago
  Protonmail = privacy at all costs. Thundermail = freedom at all costs (open standards, use w/ whatever client you want, upload your own encryption key and "go dark")
  - Ritewut 6mo ago
    I assume if I upload my own key, the receiver of the emails needs to also have my key? I'm not necessarily trying to send encrypted emails to people. I would want zero-access encryption which means not even Thundermail knows what my emails are.
    - ryanleesipes 6mo ago
      No, we rely on PGP encrypted email. What I'm talking about is the latter. Emails are encrypted with your public key before being stored in the database. (Our stack is based on Stalwart, you can read about how it works here: https://stalw.art/docs/encryption/overview https://stalw.art/docs/encryption/overview )
      - Ritewut 6mo ago
        Thanks for explaining the broad strokes. I'm a bit more interested now and signed up on the waitlist.

Since most of the people here who seem wary about how their donation is getting spent, I have a feeling that "mostly on devs" probably won't cut it for them, though I assume it's true. Have you considered doing any sort of year end cost reporting where you show percentages of what money went where? If it's going where you say it is I think making that information transparent would be a free win. (I know there would be some level of effort constructing the report but I also have to assume you already have reports like this internally)

If you are serious about winning back donors and trust: - Allow for a transparent breakdown of expenses on things like external consultancy and also C level compensation - Allow financial ring-fencing of donations. Such that my donation can only finance Firefox devs or Thunderbird devs. (Not teams, not products, not managers/VPs/Directors just developers. Everyone else's compensation should come from corporate donations or other means) I love Firefox and Thunderbird, use both everyday, was also a yearly donor up to 2020 (now I just donate to Archive.org and KDE). You have great products that people love but if you are serious about gaining back trust you need to show judicious spending on the top side of the org. Justifying it with we need to spend money to get fundraisers doesn't pass the community test.

I've been trying to use Exchange support at work but there's an ongoing problem that the OAuth login screen can't display PIN prompts for things like Yubikeys. So I'd love to use the feature, but modern corporate auth defeats it currently.

fhackenberger 6mo ago
As a user from Germany, it would help a lot if you could provide an IBAN to send you money in EUR directly. These payment providers all take a cut and what ends up being used for recurring donations is SEPA direct debit, which costs me about 10€ if my account ever happens do be too low to take the charge. Please make a way around supporting this ecosystem of banking with every donation!
nevermined 6mo ago
I've been using Thunderbird exclusively for as long as I can remember (Internet user since '92). I don't understand why they make it so hard to donate anonymously. I actually found their IBAN (DE05 5123 0500 0500 2158) on the Google results page, not on the page it linked to. Annoying.
