    Protonmail is a closed platform, and have no similarity between Mailfence (except in a sense that they both use OpenPGP as their end-to-end encryption technology).

    It's entirely outside of US jurisdictions - just like Mailfence. It uses end-to-end encryptions - just like Mailfence, and in fact, even ProtonMail cannot access your information, so it is BETTER than Mailfence, in my opinion, in terms of security.

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