What you can do
Thunderbird is a powerful, privacy-focused email app. Effortlessly manage multiple email accounts from one app, with a Unified Inbox option for maximum productivity. Built on open-source technology and supported by a dedicated team of developers alongside a global community of volunteers, Thunderbird never treats your private data as a product. Supported solely by financial contributions from our users, so you never have to see ads mixed in with your emails again.

What you can do

• Ditch multiple apps and webmail. Use one app, with an optional Unified Inbox, to power through your day.


• Enjoy a privacy-friendly email client that never collects or sells your personal data. We directly connect you to your email provider. That’s it!


• Take your privacy to the next level by using OpenPGP email encryption (PGP/MIME) with the “OpenKeychain” app, to encrypt and decrypt your messages.


• Choose to sync your email instantly, at set intervals, or on-demand. However you want to check your email, it’s up to you!


• Find your important messages using both local and server-side search.

Compatibility

• Thunderbird works with IMAP and POP3 protocols, supporting a wide range of email providers, including Gmail, Outlook, Yahoo Mail, iCloud, and more.

Why use Thunderbird

• The trusted name in email for over 20 years - now on Android.


• Thunderbird is fully funded by voluntary contributions from our users. We don’t mine your personal data. You are never the product.


• Made by a team that is as efficiency-minded as you are. We want you to spend minimal time using the app while getting maximum in return.


• With contributors from all over the world, Thunderbird for Android has been translated into more than 20 languages.


• Supported by MZLA Technologies Corporation, a wholly owned subsidiary of the Mozilla Foundation.

Open Source and Community

• Thunderbird is free and open source, which means its code is available to see, modify, use and share freely. Its license also ensures that it will be free forever. You can think of Thunderbird as a gift from thousands of contributors to you.


• We develop in the open with regular, transparent updates on our blog and mailing lists.


• Our user support is powered by our global community. Find the answers you need, or step into the role of a contributor - whether it’s answering questions, translating the app, or telling your friends and family about Thunderbird.

Ratings and reviews

While you can tell its a beta, I've not had any issues aside from navigating the settings panels. Some items don't seem to be in the most intuitive areas and I'm currently struggling to find a place to edit the starting options such as how often to refresh the accounts. But other than that, it's been smooth sailing, literally, the animations are good (a bit drawn out, I'd like an animation scale slider) the notifications are collapsed, while including all emails in the refresh (good thing)

As mentioned won't port k-9 settings, but it auto-recognized the right configuration. Really easy. Only using for a few days, the big issue for me is visual. It's hard to see the difference between read and unread messages. Not enough contrast or difference. K-9 used line shading, easy to see. Sort of annoying to be wondering if I read a note or not. Also when reading an individual message, I need larger font. Sometimes the message won't render right. Can't recall that happening with k9.

I want to use this so so bad but it just can't do what I need it to yet. I "enabled" push notification (yes there is an option but it's buried currently), but it's grossly inconsistent for when the notification will come through, anywhere from instantly to 10+ minutes. And even though I have it set to download images automatically, not all images download and there is no way to download the ones that didn't. It's still early so I'm hoping these can improve, but these are a big obstacle.
