ProtonMail: Free, Simple, Secure Email

ProtonMail is a Swiss-based Email service with modern encryption ensuring that only the sender and receiver(s) of a message will be able to read its contents. This implementation of end-to-end encryption happens automatically when email is sent between ProtonMail users.

ProtonMail is the best way to use email with modern security and simplicity in mind. It completely eliminates the need for any of the popular email providers that cannot provide communication security.

It will be great to see how the app develops as new features are added to make this secure email service even more convenient.

Good but work on the notifications

The app is good but the notifications for ios needs to be fixed asap. Sometimes it is delayed, sent in the wrong order and even worse I sometimes get a notification for an already read mail! Work on this and the five stars will be all yours.

Best service and amazing app

If you are looking for the best email service available, look no further. ProtonMail (Only the name is not ok in my opinion), will give you the privacy, speed and reliability that you need.

It's 5 stars all the way at every new version!
