An exhaustive guide to Gmail alternatives

Seems a bit nearsighted to accuse every service of malice and then completely ignore that tutanota fixes lackluster pgp encryption by also encrypting the subject line.

This works virtually identically between both providers, except that Tutanota encrypts both the message body and subject line, whereas ProtonMail only encrypts the message body. This doesn’t pose a huge risk if you use the former service. Just make sure that your subject lines don’t contain any sensitive information. source

PGP and SMIME can’t encrypt the header which include subject, from, to, cc only the body of the endo, the text is encrypted. This is how encryption of email works.Tutanota don’t use a standard encryption system this means also the subject is encrypted but it is not compatible which 99 % of the other email providers.If ProtonMail get a court order to get access to the mailbox they can only give them the access to the mailbox without the pgp key. So they see the header / subject but all encrypted contacts and the body of the emails are secure.If tutanto have to do the same they get less information.You must choose what’s more important for you.

Not sure if this is entirely true, it is possible Proton mail is encrypting everything at rest (with the users public key) and only following PGP mail limitations during transit.

Like for example plaintext emails are encrypted at rest on Proton mail, what isn’t ideally (compared to e2ee) but still minimizes the attack surface.

Actually for reference this is exactly the case

Message storage All messages in your Proton Mail mailbox are stored with zero-access encryption. This means we cannot read any of your messages or hand them over to third parties. This includes messages sent to you by non-Proton Mail users, although keep in mind if an email is sent to you from Gmail, Gmail likely retains a copy of that message as well. Password-protected Emails are also stored end-to-end encrypted. Subject lines and recipient/sender email addresses are encrypted but not end-to-end encrypted.

Cool, thank you for clearing that up!
