The 5 Best Secure Email Services for 2024 (2024)

An encrypted email account protects your privacy. If you want more anonymity, use your secure account behind a free, anonymous web proxy serveror a Virtual Private Network (VPN) service.

ProtonMail

ProtonMail is a free, open-source, encrypted email provider based in Switzerland. It works from any computer through the ProtonMailwebsite and also through Android and iOS mobile apps.

The most important feature when talking about any encrypted email service is whether or not other people can access your messages, and the answer is a solid nowhen it comes to ProtonMail, as it features end-to-end encryption.

Nobody can decrypt ProtonMail messages without your unique password, not even employees at ProtonMail, its ISP, your ISP, or the government.

ProtonMail is so secure that it can't recover your emails if you forget your password. The decryption happens when you log in, which means the service doesn't have a means of decrypting emails without your password or a recovery account on file.

ProtonMail also doesn't keep your IP address information. With a no-log email service like ProtonMail, emails can't be traced back to you.

The free version of ProtonMail supports 1GB of email storage and limits usage to 150 messages per day.

Purchase thePlusor Unlimited service for more email storage, email aliases, priority support, labels, custom filtering options, the ability to auto-reply, built-in VPN protection, and the ability to send more emails each day. Business plans are also available for organizations.

Hushmail

Hushmail is an encrypted email service that's been around since 1999. It keeps emails secure and locked behind state-of-the-art encryption methods. Not even Hushmail can read your messages; only someone with your password can do so.

With this service, you can send encrypted messages to users of Hushmail as well as non-users who have accounts with Gmail, Outlook Mail, or other similar email clients.

The web version of Hushmail is easy to use and provides a modern interface to send and receive encrypted messages from any computer.

When creating a new Hushmail account, choose from a variety of domains to use in your address, such as @hushmail.com or @hush.com.

There are several personal and business options when you sign up for Hushmail, but none are free.

CounterMail

If you're seriously concerned with email privacy, CounterMail offers a secure implementation of OpenPGP-encrypted email in a browser. Only encrypted emails are stored on CounterMail servers.

Additionally, the servers (which are based in Sweden) don't store emails on hard disks. All data is stored on CD-ROMs only. This method helps prevent data leaks, and the moment someone tries to tamper with the server directly, the data is likely lost.

With CounterMail, you can also set up a USB drive to further encrypt email. The decryption key is stored on the device, and it, too, is required to log in to your account. This way, decryption is impossible even if a hacker steals your password.

The added physical security of the USB device makes CounterMail less simple and convenient to use than other secure email services, but you do get IMAP and SMTP access, which you can use with any OpenPGP-enabled email program, such as K-9 Mailfor Android.

After the 10-day free trial, purchase a plan to keep using the service. The trial includes 100 MB of space.

​Tutanota

Tutanota is similar to ProtonMailin its design and security level. All Tutanota emails are encrypted from the sender to the receiverand decrypted on the device. The private encryption key isn't accessible to anyone else.

This email account is all that's needed to exchange secure emails with other Tutanotausers. For encrypted emails outside the system, specify a password for the recipient to use when viewing the message in a browser. That interface allows them to reply securely, too.

The web interface is user-friendly and there's a search function so you can search for previous emails.

Tutanota usesAES and RSAfor email encryption. The servers are located in Germany, which means that German regulationsapply.

Free accounts can create an email account using a Tutanota domain, while paid plans can create custom domains. Tutanota domains are: @tutanota.com, @tutanota.de, @tutamail.com, @tuta.io, and @keemail.me.

Several features in this service are only available on paid plans. For example, the Revolutionary edition provides 15 aliases, while the Legend plan expands the storage to 500 GB.

Mailfence

Mailfence is a security-centric email service that features end-to-end encryption to ensure nobody but you and your intended recipient can read your messages.

The service includes an email address and web interface that incorporates OpenPGP public key encryption. Create a key pair for your account and manage a store of keys for people you want to email securely.

This OpenPGP standardization means you can access Mailfence using IMAP and SMTP with secured SSL/TLS connections through the email program of your choice. You cannot use Mailfence to send encrypted messages to people who don't use OpenPGP and have no public key available.

For online storage, a free Mailfence account provides 500 MB, while paid accounts offer ample space as well as the option to use your own domain name for your Mailfence email address.

Mailfence's softwareis only available for inspection by auditing teams, academic researchers, and other reputed groups because it's notopen source, making it less secure and private.

Mailfencestores your private encryption key on Mailfence servers but insists it can't be read because it's encrypted with your passphrase (via AES-256), and there's no root key that would allow the service to decrypt messages encrypted with your keys.

Mailfence uses servers in Belgium, so it's only through a Belgian court order that the company can be forced to reveal private data.
