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

You can't insert signatures or hyperlinks mobile. The app on my smartphone always opens with the empty outbox of my main account. To fix it, I uninstalled the app, deleted all cookies, tried other things, nothing worked. Notifications don't work. The app works on laptop, but for mobile you should consider alternatives. On desktop version, I have no idea how to search for a mail. On the smartphone there is a search icon, but no similar option on the desktop version. I'll look for another mail app

great app, but i missed a few features. - if I search something, I want to go right back into the search and not type it in again completely - the Desktop version has mail-filters, i would love to see them in the mobile version too - also important signature filed (like html etc.) - and deleting/creating email folders from the mobile app, why do I need the desktop client to do that?

So far it has been a smooth experience. I valued a lot the possibility to simply export the configuration from the Thunderbird desktop client, it really made my life easier. I'm just missing some features, like using a different color per account or adding an email signature. Edit: It turns out you can actually change the color and the signature. In settings, if you select a specific account, you access account specific settings. Thanks for pointing this out, I didn't notice before!
