📨 K‑9 Mail heritage
Thunderbird for Android is based on K‑9 Mail, a long‑standing open source email app. The projects share much of the same code and therefore may look and feel similar.
Some features are selectively enabled in Thunderbird when they are a better fit for Thunderbird users (e.g., import from K‑9).
If you prefer to keep using K‑9 Mail, you can find it here:
