    • Mail is encrypted prior to forwarding to my gmail, so not even my ISP can access the content in my emails. And I can set up to be alerted if I have received new mail, without the mail automatically forwarding. helloworld12Apr 2017 • 1 agrees and 0 disagrees Disagree   Agree

    • 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 • 15 agrees and 1 disagrees Disagree   Agree

    • The whole point of switching to an encrypted email provider (Protonmail, Tutanota, etc.) is to avoid the prying eyes of the company's techies, government surveillance and hackers to breach the servers.

    • Posteo could be a good Protonmail alternative. It offers email encryption in a similar way: Posteo's people, government surveillance and successful hackers won't get into your email content.

    • 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 • 1 agrees and 0 disagrees Disagree   Agree

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

I'm still waiting on a tool to import existing mail from my domains hosting my eMail. It is meant to be in the works now...


Now you can use ProtonMail Bridge to do that.

App ever coming? Tutanota is way ahead

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.


App available for Android and Apple since 12 july 2016

yes the apps is available but you still have to being authenticated by Google via the GooglePlay to launch the app, which is a non sense for me.
