Gmail may be the world’s most popular email service, but that doesn’t mean it’s the most secure. In fact, Google’s admitted to regularly reading users’ messages to better serve them ads. While the practice has since been said to have stopped, the fact that Google could read your supposedly secure messages in the first place is enough to cause concern.

Fortunately, there are other email options today besides the big three.

What does encryption mean, in terms of email?

When talking about encrypted emails, it’s important to remember that not every service is created equal: Some providers store emails in a way that cannot easily be accessed, while others offer self-destructing messages that will erase your tracks.

But by far most secure way to hide the contents of your email is to encrypt them with PGP, for pretty good privacy. Some email providers make this easier too, although there are security concerns about leaving your PGP key on a website.

Still, as we send messages from one recipient to another, metadata is always left behind, and if a recipient uses an unencrypted messaging service, it will eradicate any privacy protections you think you have.

It’s important to know how your email provider works and how it handles outside messaging services.

ExpressVPN’s picks for secure email providers

If you’re in the market for a more robust and secure email provider, check out ExpressVPN’s top picks. And, with each service sporting a free version, you can try them all before you decide which one works for you.

1. ProtonMail

Developed in 2013, ProtonMail has a long and reputable track record of providing users with a legitimate encrypted and anonymous messaging service.

Headquartered in Switzerland, ProtonMail is arguably the most trusted email provider today. Unlike U.S.-based email services like Gmail and Outlook, which are often forced to turn over sensitive documents, ProtonMail has no such obligations and is, therefore, the smarter choice for people who may be worried about sending potentially sensitive documents online.

As a secure messaging service, it’s second to none.


  • 100% open-source
  • Offers end-to-end encryption, two-factor authentication, and self-destructing messages
  • Dedicated mobile apps for Android and iOS
  • Allows file sizes up to 25 MB and free mail storage up to 500 MB
  • Different pricing options, but the free version may be enough for most

Bottom line:

If you care about your privacy (and we assume you doafter all, you’re reading this article), then ProtonMail is the gold standard encrypted email platform. With the ability to create self-destructing messages, ProtonMail members can send encrypted messages to any recipient, regardless of which email service they use.

With an easy-to-use interface, robust encryption protocols, and dedicated mobile apps, it’s definitely the cream of the crop.

In September 2021, it was reported that ProtonMail removed “by default, we don’t keep any IP logs” from its privacy policy. This action was tied to the arrest of a French climate activist. French authorities issued a request through Interpol to Swiss authorities for information on the activist’s ProtonMail account. As a Swiss company, ProtonMail is bound by Swiss law to comply with such requests and was thus required to turn over the activist’s IP address and browser fingerprints to Swiss law enforcement. To reiterate, ProtonMail were bound by law to begin logging account information for this particular account—a decision they were not happy with undertaking.

2. CounterMail

With more than 4,000 different types of PGP encryption keys, CounterMail’s a force to be reckoned with. The service itself is headquartered in Sweden, giving it a leg up in terms of privacy protections.

CounterMail also uses end-to-end encryption and is one of the only known email providers to offer its own secure USB key option, which makes it an excellent choice for people constantly sending secure messages on the go.


  • Fully anonymous email service
  • Headquartered in Sweden
  • Uses OpenPGP with 4,096 different encryption keys to safeguard your messages
  • Includes Linux, Mac, Android, and iOS support
  • One-week free trial, with subscription plans starting at $6.33 a month

Bottom line:

A veritable powerhouse of encryption protocols, CounterMail is a great service with a strong focus on user privacy. The site itself may look like something straight out of Windows 95, but the service is top class.

While CounterMail offers a one-week free trial, subscription plans start at roughly $6 a monthmaking it the most expensive email option on this list.

3. Mailfence

Launched in the wake of the Snowden revelations, Mailfence is another email service that offers encrypted messages with a strong focus on user privacy. By using OpenPGP, this service ensures that only the sender and recipient can read messages.

Unlike other encrypted email providers, it also comes with a host of other features, including digital signatures, built-in calendars, and more. Mailfence has also recently added the ability for users to communicate with non Mailfence users.


  • Headquartered in Belgium
  • Uses two-factor authentication and automatically detects and blocks spam
  • Features highly customizable email settings
  • Lets users import their information from Outlook and Gmail
  • 10 MB attachment limit with 500 MB of free storage
  • Dedicated Android and iOS apps


Bottom line:

Mailfence is a versatile email platform that donates 15% of its yearly revenue to the Electronic Frontier Foundation. That said, the free version generally offers more than enough storage and options for most users.

4. Tutanota

Another great open-source email service, Tutanota uses end-to-end encryption to keep your correspondence secure.

Unlike other messaging services, it also automatically encrypts all in and outgoing messages regardless of which email service the recipient usesa great feature if you’re writing someone outside your known network. However, the company is headquartered in Germany, which may or may not raise a few red flags.


  • Completely open-source and uses end-to-end encryption on all messages
  • Offers dedicated apps for iOS and Android
  • Gives non-Tutanota users a secure link to read encrypted messages
  • Allows up to 1 GB of free storage; unlimited storage costs 1 euro a month


Bottom line:

With more than two million active users, Tutanota is a popular service with a dedicated following. That said, the service doesn’t currently support PGP encryption, which automatically knocks it down a few pegs.

As a free secure messaging service with dedicated apps and the ability to send secure messages to recipients outside the Tutanota network, it’s a worthy contender.
