The email comes into their server unencrypted. They promise that they will encrypt it for you, though. Of course, you’re also relying on the sending server to keep the message secure as well.
Proton Mail’s end-to-end encryption and zero-access encryption ensure only you can see your emails. Not even Proton can view the content of your emails and attachments.
The vast majority of senders do not send email using end to end encryption. If you’re sending an email from a PM address to another PM address, sure, it’s end to end encrypted. If you’re sending to another service, it’s not end to end encrypted unless you’ve both gone through the painful steps of setting up PGP encryption. Same as if you’re receiving from another service.
So that quote you just responded with is saying exactly what I had just said above it. They promise that they’ll encrypt that unencrypted email that just came into their server for you. And they promise that they’ll encrypt that unencrypted email you just sent outside their service.
I know, but I was answering the question about encryption, rather than users. Proton also allows sending encrypted to non participating receivers. They get a weblink and have to open it to view the email a with password if supplied. That decrypts the email at the browser, and has an expiry time on the link.

That’s a very different use case than a fax. I mean, why even use email for that?
I wouldn’t, fax is gone once it has arrived, assuming store transmissions is off. Email is sitting in limbo on a server waiting for an exploit
