    • 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. JohnFastmanDec 2016 Disagree   Agree

    • also privacy orientated, like protonmail. Guest • Mar 2016 Disagree   Agree
    • StartMail is run by the privacy-oriented folks behind StartPage search engine. StartMail is an encrypted email service that is very similar in functionality to ProtonMail and tries to take the inconvenience out of using PGP for secure email communication. Worth considering, for sure. JohnFastmanDec 2016 Disagree   Agree

    Commercial Web / Cloud Windows Mobile Android iPhone Android Tablet ... iPad Kindle Fire

    • Mailbox.org is a partial replacement for Protonmail. It offers a fully functional email solution (email, calendar, contacts), but with the added benefits of PGP encryption support (you can handle the keys or let them do it). It also allows you to send links to people who don't use PGP if you want to send private messages. For the encryption, it's a bit like Protonmail. For everything else, it's like a privacy-respecing Gmail alternative. JohnFastmanDec 2016 Disagree   Agree

App ever coming? Tutanota is way ahead

Comment by Robino
about ProtonMail and Tutanota Apr 2015

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.

Both honesty and truth are important

For everything else there's Dovecot, IMAPS, and EXIM.
