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.

Have edited my review regarding push notifications. There is a roundabout way of doing it. It's very unclear when installing the app. Your team needs a better way to set up the app for new users. Whole point of email is to receive email and know it's there. When installing the app... No notifications are even active. The complete opposite of what a user wants. You shouldn't have to dig through menus to setup notifications.

Thanks for your feedback. From feedback like yours, we know this is a pain point, and we're working on making our folder settings more intuitive to find and use. Sorry for any frustration, and you can follow our development progress every month at blog.thunderbird.net

I've been using Thunderbird on desktop for many years and I love it. But the Android app doesn't work very good. Emails arrive much later than a few other email apps I tried, and happens with all my email addresses (Gmail, Outlook, work email). I tried changing all possible settings, including Android battery settings, and waited for a few days, but no change - emails arrive from a few minutes to half an hour late.

Having just converted my desktop to Thunderbird to replace the awful 'new outlook', I installed the T-bird mobile app on my Android. Using the QR was seamless and a really great feature and I like the interface and range of options. Sadly, that's where my praise ends because it won't sync or push emails. Even when I can see an email on my desktop there's nothing on my phone, no notification on the screen or app icon. Even manually refreshing the inbox several times doesn't work = disappointing.

Thanks for trying us and we're sorry for any frustration setting up push notifications. These are enabled by folder, and for directions, you can go to Settings > Misc > Get Help > Settings and read the article 'Configure push email...' We hope this helps get push notifications working on your phone!
