About this app

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

I love Thunderbird on my desktop & laptop, been a loyal user for a very long time. However the Android app is missing a feature that is so vital to my usage pattern I can't use the app. The missing feature is the action performed when a message is deleted, there is no option to move the deleted message to another folder (trash). The only options are to delete the message off the server or not. By moving a message to the trash folder I preserve the ability to retrieve a message that was deleted

No ads/AI/data mining/promotions! :) For those who don't know, check out Thunderbird's mission/Mozilla's mission and read up a little bit. Open standards and protocols, accessible and open web, completely open source, transparent, you can vote on features and view public roadmaps of what devs are working on and implementing And the holy grail: they don't mine or sell any data App is clean and modern and supports any email address you need it to, no bugs or crashes, no ads, no promotions, no AI

This was so close to being a perfect email client, except it IGNORES BOTH SYSTEM font display AND accessibility settings for font size (I have both set to largest), and has no in-app options to increase the font size for reading email message bodies. The font size is EXTREMELY TINY AND CANNOT BE INCREASED. I cannot read the emails in this app. There used to be an option to increase the font size but it has been deliberately removed without any replacement! devs response doesn't work!
