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.

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.

Ratings and reviews

I used to use Thunderbird on my desktop way back. On my phone I used GMail for years. Thunderbird is SO MUCH better! It's small. It's fast! It's open source. It's actually deleting when you select to delete which was a problem with the Gmail app where emails would still be there when I check the account on the computer later. I am so glad my favorite Thunderbird is now on Android! Thank you!

i thought i liked this email client at first, but not so much now. I've been intermittently getting error messages saying that the message failed to send when I'm trying to email attachments. they sit in the outbox, and then i open it, and it says message deleted, or sometimes it just removes the attachment after sending. since this is for work, i can't afford the time to troubleshoot why this keeps happening, so I'm moving on.

Nice streamlined email app with a nice clear screen view, especially in landscape mode. Update: now the font is too small and there's no setting to change it?! My phone is already on large font setting, so I can't increase the size anymore for the thunderbird app. Now I have too uninstall and probably go back to K9.
