Is confidential mode actually trying to sell itself as an encrypted email service? Google's articles about confidential mode doesn't mention encryption [1], so I'm not sure why tutanota is focusing so much on the lack of encryption. It seems to me that confidential mode is more about providing proof of receipt via SMS, and making it slightly harder for employees to forward emails to people not meant to receive it. If wanted to send an encrypted email, I'd do my encryption and decryption client side in my own terminal. Don't ever let the service's email client get access to the plaintext. 1. https://support.google.com/a/answer/7684332?hl=en https://support.google.com/a/answer/7684332?hl=en
