    Thunderbird users want a GUI mail application. Mutt is a command line mail application. They are both good and both popular, but very much apples and oranges.

    Delta Chat looks and feels like other popular messenger apps, but does not involve centralized control, tracking or selling you, friends, colleagues or family out to large organizations. "Privacy by Design" has never been more fun.

    Delta Chat uses email, but is basically a short message application. Signal and Delta chat are similar for example.

    Thunderbird connects with servers that use standard protocols and with servers for which a plugin was developed. ElectronMail works with ProtonMail ONLY and was specifically designed for this provider. Tutanota support is deprecated since July 2019.
