This post features the top 15 secure email providers to help you keep your email communications private, confidential data safe, and ensure better email privacy.


Given the rising incidents of data breaches and message interception, using emails for sharing sensitive personal, financial, and other essential details is risky. However, no one can avoid using this medium since it remains the preferred method for business and formal communication. That’s where secure email service providers, like ProtonMail, facilitate users by offering encrypted communication features.

Are your emails safe from the ever-growing prying eyes? Unfortunately, the answer is ‘No’ unless you’re using a secure email service from providers respecting your privacy.

Protecting your email communications ensures that your personal data can never be misused.

The good news is that you can get a secure email service to protect your email activities.

So, if you want your email messages and conversations to remain as private as possible, you’re at the right place. This article lists 15 trusted providers offering the best email services to take your email security to the next level.

Top 5 secure email providers – Quick list

If you’re in a rush to subscribe to one of the secure email services, here are the five best options you can choose from.

  1. ProtonMail – An open-source, end-to-end encrypted, freemium platform with zero-knowledge and zero access technology.
  2. Tutanota – Top-notch encryption standards with a user-friendly interface. However, lacks inclusive search features.
  3. Mailfence – End-to-end encrypted email service supporting encrypted email messages to non-PGP recipients too.
  4. CounterMail – Stores emails on temporary servers in encrypted form; supports additional protection with USB key. Paid service only.
  5. Hushmail – Easy-to-use encrypted email service with a premium model and free trial; supports personal and business uses alike.

What are secure email providers?

A secure email provider differs from conventional email services as it offers features to protect your email account and content. For example, they employ end-to-end encryption that encrypts your email throughout the entire journey to the recipient. Unfortunately, there isn’t any standardization of secure email – so any service can claim to be secure. That is why you should be careful when choosing a secure email service. In particular, pay attention to the encryption and other essential features employed.

How do secure email service providers work?

What makes secure email providers different from regular services is the “security” feature backed by encryption.

Basically, the original email model employed plain text communication between clients and servers. However, despite being faster, it turned out to be an insecure method of communication vulnerable to snoopers.

Also, your messages remain exposed to the service providers, who can read everything you communicate. For instance, in certain circumstances, Google does read your emails for which the access is always ready. Likewise, the government and surveillance authorities can read your messages, or at least the metadata, to know your activities.

That’s why secure email services use encryption protocols to protect your messages.

Primarily, the services use encryption in the following two ways.

Transport-level encryption

Transport-level encryption is powered by TLS – SSL‘s successor- to encrypt emails during transit. Yes, this is the same TLS you frequently encounter while browsing websites.

In the case of emails, TLS applies on top of TCP (Transmission Control Protocol) to protect SMTP (sending email to server) and IMAP (retrieving email from the server) protocols. That’s how it protects messages from the sender to the receiving end, given that the server at both ends supports encrypted communication.

Transport-level encryption basically secures your plaintext emails from hackers and snoopers.

However, unfortunately, it’s not always used by email services by default. Also, you can’t get an idea about its active status the way you can get a hint of it via a padlock with website URLs.

End-to-end encryption

In this case, the email service provider applies encryption from the sender’s “end” to the receiver’s “end” with no intermediary servers involved.

In the case of transport-level encryption, the email provider’s servers control the transmission of secure messages. The servers can store and even read your emails; hence, anyone intercepting or hacking the server can access your messages.

But in the case of end-to-end encryption, the encryption begins right at the users’ device – the endpoint. It remains encrypted during the entire transmission to the receiving end (the recipient’s device), with no chance for the server to intercept or read the email. Also, the servers (and the service provider) cannot decrypt your message since the decryption keys only remain private to the sources.

Applying end-to-end encryption is more secure and easy to use and detect. Thankfully, it comes enabled by default in most secure email services. Also, you can get a clear indicator of it when the feature is active.

Some common end-to-end encryption protocols include the following.

S/MIME: The Secure/Multipurpose Internet Mail Extensions (S/MIME) is an asymmetric end-to-end encryption protocol that works by verifying senders’ identity via signed certificates from a Certificate Authority.

PGP: Pretty Good Privacy (PGP) is a safer decentralized encryption system that utilizes symmetric and asymmetric protocols. It’s easy to use as it doesn’t require the parties to exchange private keys. However, users must rely on third-party services (such as privacy-friendly email providers) for encryption.

Why you should go for encrypted email providers

Although you can encrypt your emails with regular services, that would require additional efforts from your side. And, even after configuring everything, you can’t be sure about achieving privacy for your messages.

That’s where you need a secure email provider. Without meddling with technical stuff, you can quickly achieve better email security.

To understand how these email clients serve you, consider these obvious advantages.

Achieve better privacy

Using secure email service providers based in privacy-friendly nations is the easiest way to ensure privacy for your data. The providers in such countries warrant utmost data security, often with zero access they can easily follow due to no mandatory data retention laws. Hence, you can trust that neither your government nor any other surveillance authorities can access your emails. ProtonMail is a classic example of such robust services.

Secure sensitive data within your messages

Emails often include sensitive information such as your bank account details, passwords, and other personally identifiable information. Hence, unwarranted or malicious access to these details can easily make you fall for identity theft and other cybercrimes.

With protected email providers, you can communicate freely via email without worrying about unauthorized access to your data.

Avoid metadata tracking

While you can encrypt your emails with regular services, like Yahoo and Gmail, you remain vulnerable due to unsecured metadata.

However, your metadata may not include your full message. However, it still includes other important details such as the sender’s details, timestamps, and the overall gist of your message. Anyone maliciously accessing this data can still get an idea of your email despite encryption.

Therefore, secure email services are better as they hide your metadata from prying eyes.

Factors to consider before going with a secure email service

Many untraceable email providers are available today, making it overwhelming for anyone to choose the best service.

Some of you may seek a service with the most significant security or robust encryption. In contrast, others may fancy simplicity and convenience.

Thus, to help you pick the best secure email service, here are some factors you need to consider.

  • Email Encryption – Before switching to a provider, ensure the emails are end-to-end encrypted, including attachments.
  • Jurisdiction – You should know the service’s location and where it stores your data. These things directly affect user privacy.
  • Security and Privacy – Ensure you know the provider’s security standards and policies regarding your data. That is, whether or not it logs your data, why, how, and for how long it stores it.
  • Features – Look for essential features such as calendars, inbox search, contacts, and file storage. A secure email provider should also support DAV services and collaboration tools.
  • PGP Support Some services support PGP, while some don’t use PGP due to the vulnerabilities. It is recommended to go with a PGP-supported secure email provider.
  • Key Feature – Check if you can import existing contacts and emails. There is no harm in compromising this essential feature for security. But getting both (email security plus essential features) with one provider is an excellent win.
  • Email Apps Due to encryption, most email services won’t be used with third-party email clients. Yet, some offer dedicated apps and prefer such services.

So, to save you time, below are some of the most private email providers that we hand-picked after testing multiple of them.

The list contains both the free and paid providers. So, you can pick any of these top 15 best email services to protect your privacy.

1. Protonmail

Proton Mail
Our Rating

Free and Paid ($3.99/month)

End-to-end encryption

Limited cloud storage space

Visit Protonmail

ProtonMail is a Swiss-based, encrypted email provider. It works with iOS and Android mobile applications. The program is built as an open-source service and includes end-to-end encryption.

ProtonMail appeared on the scene following Snowden’s revelations. It is on top of our most anonymous email providers list for good reasons.

The US media has even promoted the service (Forbes, to be specific) as “The Only Email System The NSA Can’t Access.”

They have pride in data centers in under 1000 meters of granite rock, which can survive a nuclear attack.

This secure email service is also designed with the principle of zero knowledge and zero access. That means the staff and email servers cannot read or share your emails.

ProtonMail homepage

The ProtonMail free version supports 500 MB of email storage and limits your usage to 150 daily messages. That’s certainly enough for individual users.

However, you can pay for the Plus service for more space, email aliases, priority support, tags, and custom filtering options.

In the Plus plan, you can set automatic responses and send more emails daily alongside built-in VPN protection. A couple of other plans (Professional and Visionary) are also available.

ProtonMail Plans
  • 500MB free storage as well as 150 emails per day
  • Use your very own domain
  • Two-step verification
  • Free and paid options
  • Self-destruct message functionality
  • Mobile apps (Android and iOS)
  • Swiss-based servers, hence excellent protection from Swiss privacy
  • Zero-access construction
  • The Premium version is a bit on the expensive side

2. Tutanota

Our Rating



Does not support IMAP

Visit Tutanota

Tutanota is a well-protected email service based in Germany that values the privacy of its users.

Although their service aims to offer maximum email security, it remains easy to use and has quality features.

Comparing Tutanota vs. Protonmail makes both look similar in terms of design and level of security.

Tutanota uses AES and RSA encryption standards. All Tutanota emails get encrypted from the sender to the receiver (the email recipient) and decrypted directly on the device. Therefore, the private encryption key is not accessible to anyone else.

An email account is all you need to exchange secure emails with other Tutanota users.

For emails encrypted outside the system, you can simply specify a password for the email to be used by recipients when viewing the message in their browser. The very interface also allows them to respond securely.

Tutanota homepage

Tutanota web interface is easy to use and navigate, allowing you to make an email private or non-private with just one click.

However, there is no search function, so it is impossible to search for previous emails.

You can learn how it works better by reading our Tutanota guide.

  • Applications for iOS and Android
  • No phone number is required for verification
  • Automatic encryption of the entire mailbox and address book
  • The subject line, headers, body, metadata, and all attachments are automatically encrypted; the IP address is deleted
  • Support for spam filtering
  • Features like aliases and messaging rules are only available for paid accounts
  • Users cannot import contacts in bulk

3. Mailfence

Our Rating

Free and Paid ($2.50/month)

Two-factor authentication

Source code is not available for inspection

Visit Mailfence

Mailfence, headquartered in Belgium, is a security-focused email provider. Like other providers featured in this article, it offers end-to-end encryption to ensure your email messages remain secure from snoopers.

It is an excellent private email provider offering 500 MB file storage for free alongside added features.

On top of standard features, this private email provider offers a built-in Keystore, which helps manage your OpenPGP encryption keys. You also get to send encrypted messages to anyone who doesn’t use PGP.

Understandably, paid accounts offer more space and the option to use your domain name for emails.

Mailfence software is not available for inspection as it is not open source. This might undermine the security and confidentiality of the system for some users.

MailFence homepage

Mailfence stores users’ private encryption keys on its servers. But they claim that they cannot read it because it is encrypted with users’ passphrases (via AES-256).

The researchers said no root key would allow them to decrypt encrypted messages. A vast number of users online have reported Mailfence to be the most private email service.

  • Digital email signatures prove the authorship of the author
  • Includes a spam blocker
  • Import contacts from Outlook, a CSV file, vCard, LDIF, or Gmail
  • Includes a calendar and storage for documents
  • Free online storage is limited to 500 MB only
  • Requires another email address to receive the activation key
  • Private keys are kept on Mailfence servers
  • Encrypted emails can only be sent to Mailfence or OpenPGP users

4. CounterMail

Our Rating


Supports IMAP

You cannot send encrypted emails to non-users.

Visit CounterMail

CounterMail is a secure email service provider based in Sweden that has been up and running for over 10 years.

For those concerned about email privacy, CounterMail allows the secure execution of OpenPGP-encrypted email with 4096-bit encryption keys in a browser.

CounterMail servers store only encrypted emails.

The Sweden servers do not store your emails on hard drives. Instead, all data gets stored on CD-ROM only.

When someone attempts to alter the server, the data will probably disappear. That helps prevent data leakage.

CounterMail homepage

Another thing you can do with CounterMail is configure a USB key to encrypt your emails further.

The decryption key gets stored on the device while the service still requires users to log in to their accounts. That makes decryption impossible, even if a hacker steals your password.

The extra physical security with the USB device makes CounterMail a little less simple and convenient to use than most other secure email services.

You also get IMAP and SMTP access, which you can use with any OpenPGP-compatible email program.

  • Does not keep IP address logs
  • Includes an integrated password manager (called Safebox)
  • All emails and attachments are stored encrypted on secure servers (and without logbooks) in Sweden
  • Compatibility with custom domains
  • Message filter and autoresponder functions
  • Free trial for a limited time. After a week’s free trial of CounterMail, you must purchase a plan to continue using the service. The test includes only 3MB of space
  • Expensive than other secure messaging options

5. Hushmail

RunBox homepage

8. Posteo

Our Rating


Completely open-source

Unauthorized custom domains

Visit Posteo

Posteo is an affordable option in this list of secure email providers providing end-to-end encryption. This German-based encrypted email app has been around since 2009.

Although Posteo offers strong built-in encryption options, they also support IMAP. That allows you to use it with different email clients on any device you want.

Posteo goes beyond most email services to protect its users’ privacy by automatically removing IP addresses from emails. So, anyone monitoring your email traffic can neither see the location from which you sent an email nor the sender’s location when you receive one.

Posteo homepage

Notably, the service keeps no logs at all.

Besides, the provider allows you to pay for your email account through multiple channels, such as via a bank card, PayPal, or courier. That guarantees an account owner leaves no digital traces when making payments. This makes it a worthy option for journalists, activists, and people living under oppressive regimes.

Moreover, paying with PayPal, a credit card, or any other digital payment separates account information from payment details.

Posteo has no free account, but its entry-level plan offers 2 GB of email storage for €1 per month. If you need more email storage, add an extra gigabyte for €0.25 per month, up to a limit of 20 GB.

  • Mail, attachments, calendar, and contacts are encrypted with OpenPGP on secure servers in Germany
  • Supports anonymous payment (in cash)
  • Strong commitment to protecting privacy, sustainable energy, and other social initiatives
  • Self-funded; good results
  • Maximum confidentiality: no logs, deletion of the IP address, secure storage with daily backups
  • No spam folder (spam is either rejected or sent to a normal inbox)

9. StartMail

Our Rating


IMAP and SMTP support

No real end-to-end encryption

Visit StartMail

StartMail is a secure email service based in the Netherlands. Privacy enthusiasts operating the private search engine “” manage this service.

It is completely interoperable with other PGP clients due to its integrated use of PGP. That enables the users to send encrypted emails to a non-PGP user who knows a secret question to decrypt the email.

StartMail allows you to create unlimited disposable email addresses (aliases).

StartMail homepage

It has no dedicated mobile applications. But complete SMTP and IMAP support allow you to use any third-party email application with the service on almost all operating systems, including Windows, Android, iOS, Linux, and macOS.

StartMail does not have a free account but allows you to test its service for free for 30 days.

After the trial, if you wish to upgrade, it will cost you €49.95 (around 57 USD) per year. That stands true whether you choose the “Personal” (10 GB of storage and 10 addresses) or the “Business” (1 mailbox, 10 GB, your own domain) option.

  • PGP encryption in one click
  • Send encrypted emails to anyone
  • Supports two-factor authentication
  • Unlimited disposable email addresses
  • Complies with GDPR
  • Possibility to import contacts from many email services

10. Disroot

Our Rating


Multi-lingual user interface

Limited storage space

Visit Disroot

Based in Amsterdam, Netherlands, Disroot provides secure email accounts that you can use on your desktop client or through a web interface.

Communication between you and the mail server is encrypted with SSL. That provides the highest possible level of privacy.


Besides, all emails from your server get encrypted (via TLS protocol), given that the recipient’s email server supports it.

It means, in essence, the emails are no longer sent as a traditional “postcard” but are entered in an “envelope.”

  • Free 2 GB storage mailbox
  • Allows up to 10MB for document attachment at once
  • Accessible by POP3, IMAP, and web page
  • Open-source software
  • Offers useful additional services, including cloud storage, a social network, forums, and chat

Visit Criptext

Criptext is a free encrypted email service with open-source applications for Windows, Linux, macOS, Android, and iOS devices. The service is still in the Beta phase.

Criptext, the US-based service, began its journey in 2014 as a simple encryption extension for Gmail. It allowed users to have more security in their mailboxes.

CripText homepage

But, in 2015, the company became a victim of state intervention by Panama’s government. This and the increase in privacy invasions worldwide motivated them to create a secure email service like no other.

  • One of the pioneers of secure email service solutions
  • Completely free
  • Allows sending emails to people who do not have a Criptext account
  • Unsend email feature
  • Stores user information, including name, primary and recovery email addresses, approved devices, and the last active date

14. Librem Mail

Librem One
Our Rating

Free and Paid ($7.99/month)

Does not track users

Doesn’t support iOS

Visit Librem Mail

Librem Mail is an end-to-end encrypted email service included in the social networking suite Librem One. The service comes from the American tech firm Purism, which also maintains PureOS Linux distribution.

It is among the most private email services out there, using K-9 Mail alongside OpenKeychain. This combination simplifies the use of encrypted mail.

Librem One homepage

Librem Mail users can exchange encrypted emails with anyone whose email is encrypted using OpenPGP.

The provider offers two premium packages as well as a free plan.

Unfortunately, if you intend to use its secure email solution, the free plan offered by the provider won’t help. Its free plan, dubbed the basic bundle, only offers social and chat services to the users.

The two paid plans range from $7.99 to $14.99.

  • Not just secure emails, Librem One, is a one-stop shop for confidentiality and digital security.
  • Built-in VPN for maximum security. The Android application uses the code from OpenVPN
  • Decentralized
  • No ads
  • Librem One is entirely based on existing free software projects


ScryptMail went out of business on January 31st, 2020. The provider deleted entire databases available on all its servers on March 31st, 2020. We included this in our list of best secure email providers because many users might still search for this service even after its discontinuation. So, for that reason, it was appropriate to list it alongside a notice to help people know that it operates no more. And they should not fall prey to any scam because of similar names (if any, ever). The good news is, all the providers listed in this article are quality ScryptMail alternatives anyone can use.

Founded in the USA by a group of people obsessed with security, this private email service provider offered top-level encryption. Before shutting down, it allowed sending encrypted messages to any web user.


It worked like other secure email services. SCRYPTMail would encrypt metadata on its servers, putting a barrier between hackers (or government agencies) and user data.

  • Storage limits were generous, and almost all services offered by SCRYPTMail were free. That is why they were doubly attractive when the service was still available until January 2020
  • Accepted Bitcoin, hence supporting anonymous payments
  • Paid plans were a little bit expensive

How we tested the best private email providers

We first set up an account with a secure email provider and tested the service to see how it functions in various situations, purposes, and conditions. We specifically focused on the security settings to examine the accounts’ security. This includes the encryption rate and account recovery options that cybercriminals may exploit. The goal was to push each secure email provider to discover how beneficial its basic features are and the ease of using more advanced tools.

Additional steps for keeping your emails private and secure

If you use a secure messaging service that boasts end-to-end encryption, you have taken an important step to make your messaging truly secure and private.

To make life difficult for even the most passionate hackers, you can take a few extra precautions:

  • Beware of keyboard recording software that captures what you type directly from your keyboard. Such software, dubbed keyloggers, can ultimately defeat encryption if the password is all that a hacker needs to access your account.
  • Do not leave your mobile devices and computers unattended. Also, make sure that strong passwords or biometric data protect your devices and do not allow guest accounts or similar unprotected access.
  • Be careful of social engineering. Remember, phishing attempts often occur via email, instant messaging, VoIP, or social media. Also, remember that a hacker can design them carefully or adapt them to your case.
  • Do not write or share any passwords. Never write down the password that allows you to decrypt secure emails. However, you can store it in a secure password manager.
  • Employ two-factor authentication. Combining something you have (authenticator app) with something you know (password/pin) adds an extra security layer.
  • Third-party app permission. Verify the apps and devices that have access to your email account regularly. Revoke those you no longer use to reduce potential vulnerability to your account.
  • Check filters and forward addresses. This will help ensure your private messages aren’t forwarded to unauthorized addresses.

Wait, isn’t my Email already encrypted?

Some years back, Google improved Gmail’s security by adding the standard Transport Layer Security (TLS) encryption. While this is great, it is a bare minimum, and almost every website nowadays uses HTTPS.

Google claims it doesn’t read your emails. But how does it automatically sync your flight notification with your calendar? Also, it gives mail-reading permission to third-party apps.

Moreover, its privacy policy has clauses that explain when it releases your email data to government entities. So, this is a clear indication that it can hand over your information if compelled to do so. Although Apple Mail offers full-on encryption and digital signatures, you must obtain a security certificate. Initially, the certificates were free, but the list is shrinking. When you install the certificate in your keychain, your emails will be digitally signed by default. Also, if the recipient has the certificates, you can send an encrypted message by clicking the lock icon.

Do I have to change my Email address for encryption?

Starting with a new email address is beneficial because it hasn’t been used in the dark web or tracked by data aggregators. However, you must notify all contacts that you’ve changed your address and reset your online accounts. Email providers like Private-Mail, Tutanot, and Private-Mail require you to use a brand-new email address. And the new email address must be unique, as with most email services. Luckily, these providers don’t have millions of users like Gmail or Yahoo, so you can use your name without adding numbers and other characters. However, some providers allow you to use your existing email.

Need extra protection? A VPN can help a great deal

Gaining complete internet security is like assembling numerous pieces to complete a puzzle.

And a VPN is probably the most vital tool to complete your internet security puzzle for thorough protection online.

A Virtual Private Network (VPN) is a connection method utilized to add privacy and security to public and private networks (e.g., WiFi and the mobile internet).

Using a VPN is becoming popular with corporations and individuals because it protects users’ information while it travels through the internet.

A VPN can increase your privacy to the maximum level possible. That is because you get to change your real IP address with a fake one provided by the VPN provider.

Simply put, the VPN is just a way to join a network without being physically in it.

Advantages of using a VPN

And now that you understand what a VPN is, it’s time for you to know all the benefits of using it:

  • Bypass geographical restrictions
  • Avoid censorship
  • Teleworking
  • It makes your browsing more private as a whole
  • Encrypts your data transfers
  • Masks real IP (hence location)
  • Enables users to access the blocked websites

As you can see, alongside enabling you to surf the internet securely, a VPN provides several other benefits.

But here, you might wonder which VPN provider I may use for optimum results. The answer is ExpressVPN (most recommended). ExpressVPN is one of the most renowned companies in the world of VPNs.

But what makes this service distinct from others? Let’s find out quickly.


ExpressVPN is a company founded in 2009 in the British Virgin Islands. And as you may have guessed by the name, the firm offers a super-fast VPN service worldwide.

ExpreessVPN new 600x300

It’s a premium VPN provider that allows you to surf the internet anonymously through a Virtual Private Network (hence its acronym). It boasts apps that are secure, user-friendly, reliable, and well-designed.

What does ExpressVPN offer?

  • Super-fast connection speeds: It has more than 3,000 servers spread all over the world. So rest assured you get a faster connection speed regardless of your location.
  • Unlimited bandwidth: No bandwidth restrictions for the users means you can browse and download content you love without fear.
  • Dedicated applications: This VPN provider works with all the devices on the planet and has dedicated apps for all the major operating systems. That means you can get started with it in a flash.
  • Robust data safety: The British Virgin Islands has no data retention laws. That and not keeping records of your activity or connection ensure your privacy.
  • Has not been compromised ever: ExpressVPN servers have the latest technology to prevent hacking attacks.
  • Money-back guarantee: You have 30 days to get your money back if the service does not meet your expectations. No questions. We tested their money-back promise during our ExpressVPN extensive review, and the service stood true to its words.


No, you don’t need a service provider to encrypt your email. In fact, it is possible to protect your email manually. The most popular method is PGP, but everyone you communicate with must set up their emails, too. So, it is much easier to use end-to-end encrypted email services.

Many bad things can happen. For example, they can pretend to be you and request money from your contacts. Also, they can take over your other online accounts associated with the email. So, your email can help a hacker control a significant part of your online life.

It’s easier to determine when your email is hacked but harder to know if someone else is reading your emails. This is because the authorities and other third parties can tap your communication and access your message content. End-to-end encryption helps to stop unintended readers from reading your emails.
