I'm just a girl, incrementing the counter on the number of times I have been sent a plaintext email from a Protonmail user telling me that the message is encrypted.
@evacide Can you expand on that? ProtonMail loudly claims to be e2e encrypted to me, but the claims seem less than credible if mails is sent to a proton.me address from an unencrypted place like gmail

@davecb @evacide They are very clear in their marketing and documentation that e2e only works if you are sending between Proton addresses. They are more important as a Google alternative... I wish they would focus on that instead.

(Edit: to be clear, this is a response to @davecb . I know @evacide knows what she's talking about.)

@wcbdata @evacide Are there any technical reasons that prevent other encrypted email platforms from being interoperable? Theoretically, shouldn’t a Tutamail user be able to safely send an email to a Proton address?
@CAWguy I would think it's possible... 🤔 As a former PM, I'd wonder if competitive position and/or deeply embedded technical differences make it a tough sell, though.
@wcbdata ‘Competitive position’ would have been my first guess. With encryption set aside, each platform would then be exposed to competing on the best features and user experiences.
