This alternative is disputed. Gmail is still a legitimate alternative to Posteo, but it might have issues that some users think are important.

Posteo offers encrypted email. Gmail does not. This is a fundamental difference in services. In one (posteo), your email is private. In the order (gmail) your email is scanned, saved, then crunched by artificial intelligence to be used to manipulate the end user.

Posteo offers end-to-end encrypted messages, with security and anonymity in mind. Not the same for GMail.
