> The last two providers offered true end-to-end encryption
ProtonMail and Tutanota offer end-to-end encryption only when both the sender and recipient are using the same (i.e., ProtonMail->ProtonMail or Tutanota->Tutanota). If you’re emailing someone outside those or if you’re receiving emails from someone outside those, and you want encryption, you’d have to go to PGP (with its own complexities).
