What is the most secure email provider? Many people ask this question.

Today, in 2023, using a protected email service is a matter of security and privacy.  In this article, we will review the 13 most secure private email providers.

Which email provider is actually reliable? It’s true that email services such as Gmail, Outlook or Yahoo are easy to use. But do they protect our privacy? Unfortunately, the answer is NO.

Yahoo developed special software for the National Security Agency so that they could secretly check their users’ emails. During the trial, Google admitted to reading its users’ emails.

And when it comes to Microsoft, it is even worse. They were so generous that they helped the NSA monitor the users of Hotmail, Skype, and Outlook services within the PRISM project.

What are the criteria for choosing a reliable mail? Reliability is determined by the following factors:

  • Mail protection from hacking and interception by third parties.
  • Confidentiality — protection of information from the developers themselves
  • Refusal of developers to cooperate with governments and other agencies.

All services considered in this overview meet all of the above requirements. Or at least they say they do. Let’s take a look at the most reliable email services that provide mail encryption without sharing the user data with the authorities or other services.

NOTE: Add an extra layer of protection by encrypting your traffic with a VPN. See our list of recommended VPN services.
