Who of you uses one of the above services, what do you think of it?

  • Note that ProtonMail and Fastmail have quite different feature sets.

    ProtonMail does not store your Email in plain text for instance; they cannot read them or be ordered to read them. This comes with some drawbacks such as that standard protocols such as IMAP do not work without a bridge because they necessitates that the server can read all the emails.
