BEST SERVICE FOR PRIVATE EMAIL
ProtonMail is just about every privacy buff’s go-to for secure email. ProtonMail messages between users of the service are protected by end-to-end encryption so that ProtonMail itself can’t read them. It supports OpenPGP encryption for email to non-ProtonMail users, as well as a symmetric encryption system where you can send a link to an encrypted webpage that only a person with a specific passcode can read.
What’s more, mailbox data on Protomail’s servers is encrypted so that even the company can’t access it. It keeps no IP logs, requires no personal information to create an account, can have mail set to self-destruct, uses open source code and is located in Switzerland, which has some of the world’s best privacy laws.
Recommended alternative: MailFence ( mailfence.com). There are quite a few good alternatives to ProtonMail (HushMail and Countermail, for example), but MailFence has a simplicity that we really like. It uses OpenPGP for end-to-end mail encryption, and while it stores keys on its servers, those keys are protected by a passcode only you have.
