Yes, SMTP is insecure. Protonmail emails are end-to-end encrypted at rest. So server admins or whoever can’t just look at all your emails whenever they want, potentially years after they’ve been received. Contrast that with Fastmail, Gmail, or other providers. At any moment someone who works there can look at customer emails. I prefer my emails encrypted at rest.
