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

Slick, solid, does everything I want. I installed Thunderbird on a recommendation, because I was unhappy with the Samsung mail app. I was unhappy because it would not let me set reply-to addresses, would not let me reorder accounts in the list, and could not handle accounts with different servers for sending and receiving. You may say those are only things a power user would want, but I needed them. Thunderbird delivered on all of them, and is very nice to use.

Really on board for this app! I've had so many issues with so many apps but I think I might finally be able to settle. Only one bit of feedback I'd really liked implemented—RTF or html signatures! I want my signature to be the same as it is on my desktop, where I've gone to the trouble of making a nice html signature but no matter how hard I try (including importing settings from TB desktop, pasting from existing formatted text) this app de-formats my signature to pure text with no formatting.

I’ve tried a lot of Android email apps, and Thunderbird is the one that’s staying on my phone. It’s open source, has no ads, no subscriptions, and works well with my email accounts. I love that I can share links from emails directly to my URL-cleaning app instead of the usual copy-and-paste faff in Outlook. My only gripe is the light theme. The grey text is too low-contrast, and a high-contrast option plus more colour theming would make the app almost perfect. A solid email app.
