It doesn't sound like they do on-disk encryption like ProtonMail. Is that right?

You mean e2e? on-disk encryption (ie. "encryption at rest") is basically used by everyone, including gmail and outlook.

  • You can tell how well I've researched this ;) but yes.

    • Indeed. The HTTPS connection is enecrypted, and they TRY to use TLS first when delivering mail, but it will fall back to cleartext easily if the other end doesn't support TLS.

Mailbox doesn’t support it, but on mailbox you can use your IMAP app with Proton not.

And on mailbox you can easily send and receive PGP encrypted mail on mailbox.org. They provide a page for key import, allowing you to send encrypted emails like regular mail when needed.

It’s your choice, if you always want to use proton mail app everywhere you can use proton.

  • I use IMAP with Proton. Thunderbird is my main mail client. You just need to install the bridge.
