Mozilla To Launch 'Thunderbird Pro' Paid Services (techspot.com)

(Tuesday April 01, 2025 @11:30PM (msmash) from the up-next dept.)


Mozilla plans to [1]introduce a suite of paid professional services for its open-source Thunderbird email client, transforming the application into a comprehensive communication platform. Dubbed "Thunderbird Pro," the package aims to compete with established ecosystems like Gmail and Office 365 while maintaining Mozilla's commitment to open-source software.

The Pro tier will [2]include four core services : Thunderbird Appointment for streamlined scheduling, Thunderbird Send for file sharing (reviving the discontinued Firefox Send), Thunderbird Assist offering AI capabilities powered by Flower AI, and Thundermail, a revamped email client built on Stalwart's open-source stack. Initially, Thunderbird Pro will be available free to "consistent community contributors," with paid access for other users.

Mozilla Managing Director Ryan Sipes indicated the company may consider limited free tiers once the service establishes a sustainable user base. This initiative follows Mozilla's 2023 announcement about [3]"remaking" Thunderbird's architecture to modernize its aging codebase, addressing user losses to more feature-rich competitors.

If they want to offer a solution that mimics GMail and O365 they're going to need to host the actual email services. People don't use GMail and O365 for the client, they use it because of the basic back end email service.

Simply having a "Pro" tier of the client for OSS means some enterprising folks will replicate the tier functionality with free addons.

Yes. That's the "Thundermail" part of the Pro Package though the Summary mangles it/confuses it.

"To deal with Thunderbird's technical debt (which Andrew Sutherland described on the Mozilla Governance thread that Mitchell Baker started), I propose Mozilla fund a "skunkworks" team of about seven people for a year to create a new server version of Thunderbird (called "Thunderbird Server", or "ThunderbirdS" for short) that runs initially as a locally-installed Node.js app providing a single-page JavaScript/TypeScript/Mithril/D3 webapp for email handling and other peer-to-p

It's very VERY unclear what that offering is. Will they host my domain? Are they just a relay? This needs to be expanded in order to know what they are REALLY offering and how secure the services might be.

I certainly use Gmail for the client. Having access from any device, and fast search capabilities, is very helpful. A local Thunderbird client couldn't do that, unfortunately.

That said, there are many problems in Gmail, especially privacy wise. I expect there would be some with any free to use cloud email service. They have to be paid for somehow.

I used to roll my own mail server in my 20s, but that got a little bit old to maintain.

"Feature Rich" is a time-honored foolhardy mistake.

Thunderbird has been the go-to mail client of choice for over 20 years.

Thinking that they had to compete with the bloated and slow Outlook was a mistake.

I want a slim email client, and Thunderbird is moving faster and faster away from that. Outlook may be the competition, but making all those mistakes is not the solution.

Doing these things isn't the solution to the problem that you're talking about, but the problem that you're talking about is not the problem that they are trying to address. Mozilla is currently heavily dependent on Google for revenue (it's something like 80% of their total revenue), and that is the problem that they're focused on.

They need to compete with Outlook because people pay for Outlook. No one pays for Thunderbird.

"comprehensive communication platform"

No one wants another Microsoft 365. In fact, no one wants the first M365 either. It's too bit, too clunky and trying to much than it's healthy for it to do.

Do you want to do something that people would buy instead of M365? Create an email client that is just an email client. A product that does a single job and does it well.

Like Thunderbird? It is a pretty good email client. It's OSS, cross platform, I use it with several email providers and it pretty much does what I expect from an email client. Also, K9 on Android FTW.

That said, I'm really glad they're actually building something that can generate recurring revenue, that isn't a fly-by-night shitcoin or LLM play, or yet another data-generating useless service glued on to Firefox.
