CryptaMail

As its name suggests, CryptaMail is an email platform that automatically encrypts all your emails making them 100% private and secure.

With CryptaMail, you’re the only one who can access your emails, there are no central servers and third-parties involved in the email platforms’ architecture.

As the team behind the project explains: Even we cannot locate your messages or derive your password, ever. ONLY those who know your password have access.

Your messages are not stored on a physical server, they are kept on the blockchain which guarantees the secure transmission of transactions. CryptaMail is built on the NxtCoin protocol.

The platform is currently in beta but you can already test it and reserve your username.

ProtonMail

ProtonMail is not based on blockchain technology but uses very strong end-to-end encryption protocols that make it impossible for anyone to access your emails.

Absolutely all your emails are secured automatically and nobody can decrypt, read, or share them with third-parties.

Your emails are encrypted on every network nod. Emails are encrypted even before they reach ProtonMail’s infrastructure. Then, when the network redirects your message to the recipient, it transmits it in an encrypted form.

This double encryption solution reduces the risk of message interception to zero.

ProtonMail doesn’t require you to add any personal information when creating your email account. There are no IP logs stored either.

It is worth mentioning that the ProtonMail code is open source and you can check it out on GitHub at any time. The project gets its fund through donations and paid accounts.

  • While ProtonMail is a decent service, it’s NOT decentralized and it’s NOT open source. Only their client app is open source. The server is not. Also, not all your mail is encrypted end to end. Only mail that originates on protonmail and ends on protonmail (both users are on protonmail). If you send mail outside of protonmail, it’s just regular email, like everything else. If you receive e-mail from outside sources, it’s regular email, like everything else.

    Protonmail is centralized, on their own servers, is owned and run by an entity, and if they go away, so does protonmail. Don’t get me wrong. I like ProtonMail and have accounts there, but it shouldn’t be on this list of decentralized e-mail systems.
