If you press the browser’s back button on the donation page, they send you to a page pestering you for your email address so they can send you a reminder to donate later. Talk about a dark pattern.
Mozilla has really gone off the rails. An organisation who claims to work on behalf of the user and who makes a web browser, actively hijacking the user experience to peddle for a few dollars?
Why the heck is Thunderbird “fully funded by financial contributions from [their] users”? Where do the billions of dollars from Google go? All the stupid doomed side projects which no one asked for nor wants and are abandoned after one year?
Campaigns like this need more info. This page doesn't answer any basic questions.
How much money do you currently get? How much money do you need and how will you use it? Does it even go directly to Thunderbird development or will be used up by Mozilla for other projects?
> MZLA Technologies Corporation is a wholly owned for-profit subsidiary of the Mozilla Foundation and the home of Thunderbird.
I guess I don't understand why the open-source email client with zero revenue potential is managed by a for-profit subsidiary, nor why that for-profit subsidiary is begging for donations.
Shouldn't this whole thing be managed by the non-profit Mozilla Foundation?
I don't see them begging anywhere, I only see someone sharing a link to their donate page.
For what it's worth because legal names are confusingly similar, this is a legal subsidiary of Mozilla that is specific to Thunderbird, as in if you give it money it goes straight into Thunderbird. Many people here pretend to wish to be able to give money directly to Firefox, yet when they can do that for Thunderbird, people here are still finding bullshit reasons not to do so. Pick a lane.

Right, I get that, but why is it for-profit? Fund raising is hard enough for nonprofits, convincing people to donate their hard-earned cash to a for-profit is on a whole different level.
Not that it answers your question, but the move happened in 2020 to "hire more easily, act more swiftly, and pursue ideas that were previously not possible".
Made an account just to say that I will not support the bloated mess that is Thunderbird that pushes on you a new way to configure it, a new layout and new workflows with every major update, makes it difficult to set up text-only mail and messes up line breaks every so often with no way to properly configure it, which should be developed by Mozilla, which is flush with money but rather spends it on theming their software and executive salaries.
I switched away from Thunderbird about a year ago and couldn't be happier I have made the change.
I wish I could use Thunderbird at work now that it has Exchange support . Unfortunately we're mandated to use Microsoft Outlook. Outlook feels like it has completely been forgotten by Microsoft. I don't recall the last time they updated anything meaningful in the product (at least on macOS), it's quite a mess of a product. Wishing Thunderbird all the best it's the competition we need.
You know what is nice? If you have clients that get automatically switched to "the new Outlook" and loose all imap connections (and they don't work anymore, period).
Took me so long to learn that the fix was to switch back to the old Outlook.
IMAP works in outlook. Its just horrible to set up and half broken. Click "Add account". Then type in your email address, click "Choose provider", select IMAP, then click "Sync directly with IMAP" (dark pattern hidden button). If you don't click that last button, outlook uploads your IMAP email credentials to their own MS Cloud instance, and that proxies all your emails via microsoft's cloud servers. Do they read your email messages for advertising? Nobody knows!
In my testing, the local IMAP client implementation quite frequently launches a DoS attack against your IMAP server. It'll send the same query requesting new mail messages in a tight loop, limited by the round-trip latency. But luckily, almost nobody uses IMAP via outlook because its so difficult to set up.
There's also two different applications which are both "Outlook for Mac".
If you go into the "Outlook" menu in the app, there's a "Legacy Outlook" button, which relaunches outlook using a completely different binary. The two outlook implementations have different bugs and all sorts of different behaviour.
Outlook For Mac is free but "legacy outlook" requires a MS365 subscription for some reason.
Outlook is also not to be confused with Microsoft's "Web Outlook" client, available at outlook.live.com. It all seems totally insane.
Interestingly, I used Thunderbird for years, it was really the best client for some times on Linux. But as the development stalled, I moved to Gnome Evolution, the nice integration with the general Gnome desktop made the switch less painful (at the start, it was hard, Evolution was not that good). But Evolution improved nicely, less bugs, faster, still well integrated into the desktop and I see no reasons to switch back to another tool.
The only change in my workflow is that now, I am also using in parallel a stupid command line tool "vibe coded" in Python to read my emails. It allows me to quickly check my emails out of VS Code in a Claude Code session, a bit like when I was doing my emails directly in Emacs :-)
Mozilla is such a weird company, asking users to donate and keep one of their projects alive, while dumping billions in useless initiatives is really dishonest.
How is KMail and Evolution at this point? I have not tried them in like 10 years. Are they actively maintained and a real alternative for serious email use?
As a lot of people in this thread advise against Thunderbird, what do you recommend instead (preferably for Windows as I am stuck on that)?

Thought the same..

Mozilla brings in almost $700 million per year, they have more than enough money to sponsor MZLA/Thunderbird development.
Mozilla is so sad. They have a lot of money and they could fund the development of both Firefox and Thunderbird.
Yet, they decide to waste almost $7 million per year to pay a CEO and God knows what else.
Mozilla tried to kill Thunderbird in 2020. They've been talking about not sponsoring it all since 2015.
They might have the money, but they don't really seem to want anything to do with the project.
Mozilla doesn't have the willpower or vision to do anything with anything.
Is that a Stripe screen? Set up american style to reduce friction, not supporting 3d secure, which means european credit cards will deny by default?
Wasn't Thunderbird Pro the avenue for extra project financing? Why does it take so long to launch an email service?
Was going to say it's here, but it's not indeed, you can join the waitlist: https://www.tb.pro/en-US/

What do you use now?
I have actually bought a lifetime license for em Client.
Thunderbird had consistently (Windows / Linux) a bad performance for me and feature and UX wise it has always only been okay for me.
Still important that a few FOSS solutions for email exist, though.
em Client has no Linux version though?
Not having a Linux version in 2026 is ridiculous.

This is Microsoft we're talking about, right?

Anyone using Thunderbird was forced to see this, not sure we (or the well-funded corp) need another round.
I used TB happily for years on Mac OS but its font rendering on Linux was one of the main reasons I never switched.
Sorry, isn't Thunderbird meant to be "true FOSS" and essentially feature complete?
By donating to MZLA Technologies Corporation? Then I guess I'll switch to KMail or Evolution.
How is KMail and Evolution at this point? I have not tried them in like 10 years. Are they actively maintained and a real alternative for serious email use?
Both are ok last time I tried (last year?) but Geary is default on Gnome distro's now I think [0]. Geary is much more minimal though.
I myself am pretty spoiled by Protonmail I think, really enjoying that.
