ProtonMail, founded in 2013 by CERN researchers in privacy-friendly Switzerland, quickly became the most popular and finest secure e-mail provider.

This open-source service adheres to stringent no-logs policies and employs end-to-end encryption. Users could even send encrypted communications to recipients who do not use ProtonMail. All of their servers are kept in a nuclear bunker more than three thousand feet underground.

ProtonMail does not have a desktop user and instead relies on a web-based user that is compatible with all major browsers. After years of using Gmail, it feels awkward and out of date, but you will get used to it. When it comes to mobile devices, you may get apps for both Android and iOS.

ProtonMail’s Plus plan, among other things, provides 5 GB of storage and 5 e-mail aliases, as well as support for your domain. Meanwhile, the $24/month Visionary plan includes 20 GB, 50 e-mail alias, multi-user assistance, and ProtonVPN. Likely, it will also contain the future ProtonDrive storage solution.

This private email service provider takes privacy very seriously. To protect you, IP addresses and e-mails are removed from the heading metadata.

CounterMail, which was founded in 2008. They have kept the same website design but have come a long way to be the top secure email service provider. And, because of its security-first strategy, it may be the most secured of them all.

CounterMail employs industry-standard PGP encryption. They go the extra mile, though, by developing RAM-only servers that do not store anything. Furthermore, CounterMail protects against man-in-the-middle (MITM) attacks by including AES and RSA algorithms alongside the SSL layer. You can utilize a USB key or the Time-based One-time Password method (TOTP) with a third-party authenticator software for 2FA.

Even though CounterMail probably surpasses even ProtonMail in terms of user engagement.

Posteo – Cheapest and most secure email service provider


Posteo is a German-based secure e-mail service company that caters to both corporations and individuals.

TLS with Excellent Forward Privacy, HTTP Strict Transport Security HSTS, SSH, and other technologies are available to protect your e-mails while they are in transit. Encryption isn’t enabled by default, but it’s simple to enable with the Mailvelope software. Because it’s open-source, you’re not putting your data in the hands of an untrustworthy source.

There are also advantages that other email service providers may envy. They, for example, support the POP, SMTP, and IMAP protocols. As a result, you can retrieve the emails from your computer.

The main disadvantage is that Posteo currently lacks desktop and mobile apps. This necessitates the usage of the web client. This could be a problem because certain mobile web browsers crop the window. Furthermore, because there is no real-time chat or ticket system, you will leave waiting for some time before assistance arrives.

Although there is no free version, for a small monthly price and some minor modifications, you can receive one of the most email service providers on the market.


Considering how frequently we email these days, it’s a good thing to look at some of these programs if you value any type of security over your privacy on the internet. Some come with a free trial or free version, which is sufficient for personal usage.

However, if your firm relies on transmitting personal information, having an encrypted method to transfer those facts over could be beneficial.

Completely free email companies such as Gmail, Yahoo, and Outlook do their utmost to encrypt data, but you should question whether they truly prioritize your security.

Of course, no internet product is ever completely secure, so it’s critical to remember the basics and utilize a VPN as an added layer of protection to make it extremely tough for someone else to get illegal access.
