    Yes, there’s no other implementation I know of for provider-to-provider encrypted email. O365 is very similar. Recipients can then reply back too and the Proton user receives it directly.

        Ah yes, forgot about PGP. Haven’t used it in a long time myself, but Proton automatically creates a PGP signature for you. You can just attach your public key that’s already on your account and it’ll encrypt your mail. It natively supports PGP/MIME.
