Yes, I'm aware of that, however, I don't think sending a password-protected email requiring you to go to another website that user-friendly.

Anyways, I'm still thinking on what email service to use.

If the recipient of my mail uses a OpenPGP-compatible client (say, Apple Mail or Thunderbird), then they should be able to receive encrypted mails if they set it up correctly.

Thanks for the link!

It seems that Proton Mail is better for my use case. I'll keep my Tutanota account as a backup then.

As far as Google alternatives go fast mail which isn’t an encrypted email service is a reasonable alternative that lots of people enjoy.

I am not willing to pay for a service atm

No, Tutanota does not use PGP

You made my day!
