Thunderbird for Android 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.



Thunderbird for Android is based on K-9 Mail, which comes with a rich history of success and functionality in open source email.

## K-9 Mail



In June 2022, [K-9 Mail joined the Thunderbird family](https://k9mail.app/2022/06/13/K-9-Mail-and-Thunderbird.html)

as the foundation for Thunderbird on Android. Since then, we’ve been updating both apps to give

users the same solid experience, so it’s normal to notice that K-9 Mail and Thunderbird look and

feel nearly identical. They’re built on the same code, and that’s intentional. You'll notice some

features are selectively enabled for Thunderbird as opposed to K-9 Mail, usually when they are

simply a better fit for Thunderbird (like the import from K-9 functionality).



If you prefer the robot dog and would like to keep K-9 Mail around, you can find it here:



- [K-9 Mail on Google Play](https://play.google.com/store/apps/details?id=com.fsck.k9&utm_source=thunderbird-android-github&utm_campaign=download-section)

- [K-9 Mail on F-Droid](https://f-droid.org/packages/com.fsck.k9/)



## Forking



If you want to use a fork of this project please ensure that you replace the OAuth client setup in the `app-k9mail/src/{debug,release}/kotlin/app/k9mail/auth/K9OAuthConfigurationFactory.kt` and `app-thunderbird/src/{debug,daily,beta,release}/kotlin/net/thunderbird/android/auth/TbOAuthConfigurationFactory.kt` with your own OAuth client setup and ensure that the `redirectUri` is different to the one used in the main project. This is to prevent conflicts with the main app when both are installed on the same device.
