5 Most Secure Email Services in 2021

Traditional email services like Gmail or Outlook are far from secure and private. The companies that operate them make money by selling their customers’ user data to various third-parties, and they readily cooperate with law enforcement agencies like CIA and NSA, helping them access encrypted communication and attachments. Fortunately, there are email services that shun such practices, offering impenetrable security and privacy that you can depend on.

Not sure what they are? Here are a handful of the best choices available today.

Most Secure Email Services


1. ProtonMail

ProtonMail was founded in 2013 at the CERN research facility by Dr. Andy Yen, Dr. Bart Butler, Jason Stockman and Wei Sun, and the service has since then established itself as the most popular provider of end-to-end encrypted email. ProtonMail has servers located at two locations in Switzerland, and it uses a combination of public-key cryptography and symmetric encryption protocols to encrypt the users’ emails and other user data.

ProtonMail can be accessed either using the web browser or directly from its mobile apps, which are available both for iOS and Android. Regardless of how you access ProtonMail, you will always be greeted with a modern, optimized user interface that makes reading, organizing, and sending encrypted emails effortlessly. ProtonMail is fully optimized for use with all other email services—even those that are not secure—so you can use it as your primary email service for all your email communication needs.

2. CounterMail

CounterMail offers an automatic and transparent encryption mechanism using a strong encryption protocol called OpenPGP. Unlike traditional email service providers, CounterMail operates on a diskless architecture, which prevents CounterMail web server from leaking IP-addresses to a hard drive. Should someone ever steal a CounterMail web server, the person wouldn’t find any useful information.

CounterMail servers are located in Sweden, a country with strong digital privacy laws. Like ProtonMail, CounterMail can be accessed either through a web interface or a mobile app. Just don’t be surprised by how barebones CounterMail’s user interface is. The developers clearly value function over form, which means that the security of your email communication is guaranteed, but it also means that it might be slightly harder to use the service.
