Dark Mail is not End-to-End either. Last I looked, it had varying levels of security. The most practical one, from what I saw, is analogous to current SMTP+TLS.

It gets the keys from the "organization" (aka gmail or your mail server). Given that it is incompatible with SMTP, I don't see the point. Use Gmail, add PGP if you need it.
