- Mailpile is fantastic, but it's not really a Protonmail alternative. Protonmail is a webmail service; Mailpile is an email client, not a service. But it is good and open source... just it serves a different purpose, really. JohnFastman • Dec 2016 • 2 agrees and 0 disagrees

about ProtonMail and Tutanota · Apr 2015 · Helpful Not helpful

Protonmail is promising apps since its start a year ago. They even made it part of their crowdfunding campaign. Where did the money go? There's still no apps! I'm tired of waiting, switching to Tutanota now.
