If I'm using ProtonMail or Tutanota, while sending emails to people using other email platforms (like Gmail/Yahoo), unless I add a password to the email, it won't be end-to-end encrypted, right?
@psiie
Meaning yes?
@psiie @strawberryfieldsforever I'm unsure about Proton: I know Tutanota uses a modified version with encrypted subjects and PFS.
