ProtonMail

This free, highly secure encrypted e-mail service from Switzerland offers 500MB of storage space and complete privacy for your e-mail correspondence. ProtonMail’s “free” package can handle up to 150 messages per day from a single e-mail account. Upgrade options are available if you require more storage, custom e-mail filters, extra folders or additional aliases.

ProtonMail is among the most secure e-mail services we’ve seen and operates from Switzerland, known for its strict privacy laws. The provider uses end-to-end encryption, ensuring that messages cannot be intercepted or read by anyone other than yourself. Even the provider cannot read your e-mail!

The service is user-friendly and should be immediately familiar if you’ve used other services, such as Gmail or Outlook. The interface has been optimised for productivity and allows you to manage e-mail messages with ease. Other features include: labels for messages, draft compositions, spam handling, a trash folder, and message importance flagging.There’s also a handy search feature so you can quickly locate messages.

ProtonMail is available for smartphones (Android or Apple iOS) by downloading the relevant app. Alternatively, you can also access the service on your mobile device or computer via any popular Web browser.

Two commercial options are available (ProtonMail Plus and ProtonMail Visionary), which offer greater amounts of storage space, additional e-mail addresses and message allocations, custom e-mail filters, priority support, and additional folders. The top-level package includes multi-user support, up to a total of five different users.
