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.

Thunderbird is a 100% open source, privacy focused email app.

Good experience so far. I am a heavy user, got an average of 50 emails each day. I don't bother with the 15mints push limit, actually i do prefer to manually load instead. Had used many email apps, Outlook, Gmail and others, the only one that load more than 50 emails at once is Thunderbird. Very light, fast and customizable, simply love it. Gonna ask for just one thing, the possibility to turn auto push off, that would saves ram and make everything smoother for those who manually check the box

The Thunderbird application for PC is simply fantastic, the best email client there is. And I'm very happy to have a version of Thunderbird now for Android. Only one thing bothers me, when I receive messages from some senders, there are problems displaying certain Portuguese characters, such as ç, ã, é. It may have something to do with the encoding used by the sender, I don't know. But the fact is that Outlook and other email clients process the characters normally, as does Thunderbird for PC...

I'm loving this app. I love the unified inbox but I would also like the option to have everything unified; sent, junk, etc. Another thing I don't like is I can't seem to get my emails instantly. I have it set to the most frequent option possible (every 15 minutes) but I seem to always have to manually refresh my inbox when I'm waiting for something. ALSO the search function doesn't find as many relevant emails as other apps do, so I have to switch apps to find emails I'm looking for.
