FairEmail F-Droid | GitHub 🇳🇱 NL 👑 ⭐ ❤️ ❤
- An incredibly privacy-conscious app with lots of options and functionality.
- Once you get past the learning curve, it's probably one of the best email clients period.
K-9 Mail F-Droid | GitHub 🇺🇸 US 👑 ⭐
- K-9 Mail has long been one of the leading email clients on Android. It's mature, privacy-focused, and open source.
Thunderbird Mobile F-Droid | GitHub 🇺🇸 US ⭐
- Newer on the scene, but feature set is similar to K-9 Mail.
Thunderbird Mobile and K-9 Mail share the same code base and are, therefore, very similar. It's expected that K-9 Mail will ultimately wind down at some point, as the K-9 Mail project joined the Thunderbird family in 2022.
