The average person spends over five hours per day checking their work and personal email.

But while email is valuable and efficient, it’s not very secure. At least not if you’re using a standard email provider like Gmail or Outlook.

Email is one of the easiest ways for hackers to access your company’s data. To protect your email and all the information sent daily, you need a secure email provider.

This article introduces the top 13 secure email providers and helps you pick the right one for your business.

What Are Secure Email Providers?

A secure email provider has features designed to keep your email account and the content of your emails secure.

Usually, this is done through end-to-end encryption. End-to-end encryption means that the email is encrypted on its entire journey from sender to recipient.

However, there’s no standard definition of secure email — any email provider can call itself secure.

For that reason, when you choose a secure email provider, you have to pay attention to the type of encryption and other security practices used.

Why do you need a secure email provider?

Let’s take a look at what happens when emails are sent from a standard email provider such as Gmail to understand why secure mail is so important.

Gmail does not lack security features. Gmail and many other major providers use Transport Layer Security (TLS encryption to encrypt emails in transit between your computer (and the server)

Google encrypts data once they reach the server. Google has full access.

Google no longer scans your email to deliver ads to you, as it did in 2017. Google scans your emails for features such as Smart Reply.

Gmail and other providers can also give access to your email to third parties easily.

Now your email has left Google’s server and is traveling to its destination. TLS is used by most major email providers. The email will still be protected during transit if the recipient uses it.

If the recipient does not use TLS, then the email will not be encrypted and can easily be intercepted.

Even if an email is encrypted during transit, it might not be secure once it reaches its destination email server. Some email providers do not encrypt emails sent to them.

How can secure email providers protect your email?

End-to-end encryption is used to protect your email by the most secure email providers.

This means that even the email provider has no access. Only the recipient can see encrypted emails if they have authentication.

Providers may also use the Sender Policy Framework to authenticate your emails and protect you further.

SPF allows you to refuse an email sent by someone to your address that was not from a valid IP address.

To switch to a secure email provider, do you need to change your email address?

Most cases will require you to create a new address for your email provider.

You can forward your emails to your new email address as long as you have an old email account. Keep in mind, however, that forwarded emails are sent through the old provider’s servers so they don’t have an end-to-end encryption.

You can migrate from an old email provider to a secure email provider with additional features.

How to choose a secure email provider

Every secure email provider offers a unique set of features. These are some things to consider.

Server location

Some countries, including the United States of America, share intelligence data gathered via email servers.

If you are more concerned about hackers than the government agencies, this might not matter to you.

For activists and other people who wish to keep their email safe from government hands, an ideal provider of email would be one located in Switzerland or Germany, Norway, Sweden, Belgium, Norway or Norway. All have stricter privacy laws.


We have already talked about the differences between transport encryption such as TLS and end-to-end encryption.

There are many types of end-to-end encryption.

You can choose between symmetric and asymmetric encryption, for example. Symmetric encryption employs a single key to decrypt and encrypt data. This key must be available to both the sender as well as the recipient.

Asymmetric encryption, also known as public-key encryption or encryption, refers to two sets of keys that are used to encrypt data.

To encrypt the message, the sender uses the public key of the recipient. The public key is mathematically linked with a private key that the recipient only knows. A private key can decrypt the email.

Although symmetric encryption is slower and less straightforward than symmetric encryption it provides an additional layer of security.

Two-Factor Authentication (2FA)

It’s not enough to choose a provider that offers strong encryption. You also need to ensure your account credentials remain secure.

Two-factor authentication is a way to ensure that your password is not stolen in order to gain access to your email account. Another form of authentication is required.

The first factor is something that you are familiar with, such as a password. The second factor is something you already have, such as your mobile phone. Two-factor authentication is most commonly done by texting you a unique code that you can use along with your username or password.

Metadata Header Stripping

An email usually contains metadata about its recipient and the sender’s computer, browser, and network.

Many secure email providers strip this information out.

Open Source

Open source software makes its source code available for users and developers. This means that anyone can examine the product’s code to ensure it’s secure.

Other Encrypted Features

Your standard email provider might also provide other tools, like Google Calendar and Google Drive with Gmail.

Some secure email providers offer similar features, but they’re encrypted — for example, a secure calendar or secure cloud storage.

Usability on Desktop and Mobile

You’re switching to secure email for the data encryption, but that doesn’t mean the user experience isn’t important.

If you like to check your email on a mobile device, choose an email provider that works well on mobile. You can’t always add a secure provider to your favorite mail client app.
