K-9 Mail

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. By using Thunderbird for Android Beta, you have early access to current development and are able to try new features earlier. Check out the Release Notes to find out what changed in each version of Thunderbird for Android.

We encourage team members and contributors to read through our engineering documentation to understand the processes and decisions that have shaped this project so far. In June 2022, K-9 Mail joined the Thunderbird family 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 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.
