    • StartMail is run by the privacy-oriented folks behind StartPage search engine.

Worth considering, for sure. JohnFastmanDec 2016 Disagree   Agree

  • icon offers a secure e-mail account for home and business use. The domain name,, is easy to remember and can be understood anywhere in the world....

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

    • 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
  • These alternatives are not yet approved, do you think they are alternatives?

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.
