In this article, I’m going to offer you the best encrypted email services, alternatives to popular email services such as Gmail or Yahoo, which can also be secured to a certain degree, but, at the same time, mainstream providers are notorious for mishandling their users’ data or scanning inboxes for keywords to display personalized ads.

You may be concerned that everything you do online is being watched by the government, powerful corporations, or malicious hackers.  

In the past, we’ve shared with you what encrypted messaging apps you should use for secure communication and also walked you through the most popular free encryption software tools.

We can all agree on the fact that a huge part of our internet activity revolves around email. And I’m sure you want that everything you share via email to stay private and only be accessed by the people you choose, and the perfect way to do this is through encrypted emails.

Although there are multiple ways to secure your email using encryption software, they are often difficult to implement by unskilled users. Maybe at a later time, I’m going to also dig into this subject if you are interested, but for now, I’m going to look at some encrypted email service options that are easy to use.  

So, below I’ve put together a list of user-friendly web-based encrypted email services that will help you increase your level of online anonymity.  

You’ll notice that (almost) all of the options come from European countries. Here, the GDPR imposes strict rules on data privacy, and among many other regulations, it’s making privacy by design a legal requirement.  

Disclaimer: While none of those encrypted email services providers will share your data with other companies/advertisers, some may present it to government entities under legal demands.

1. ProtonMail

ProtonMail is an encrypted email service based in Switzerland and created by scientists, engineers, and developers from CERN, with the intention of increasing your online security and privacy. They pride themselves on datacenters “located under 1000 meters of granite rock in a heavily guarded bunker which can survive a nuclear attack”.  


  • Free option with 500MB storage and 150 emails per day
  • Paid options starting from $ 4.00 / Month for personal use
  • Business plans for $6.25 / Month / User
  • Two-step verification
  • Use your own domain
  • Mobile apps available (iOS and Android)
  • Report phishing option
  • Self-destructing messages – you can set an expiration time on your emails so they get automatically deleted from the recipient’s inbox after a certain time
  • Based on open-source code
  • They use AES, RSA, and OpenPGP encryption

2. Tutanota  

When it comes to the best encrypted email services, Tutanota cannot be overlooked. Tutanota is an encrypted email provider from Germany. They position themselves as a secure email services alternative to Gmail. According to their website, they are also planning to include a calendar, notes, and cloud storage in their offering – and of course, all of these features will be encrypted too.

Additional details:

If you want to send an email to someone who’s using different encrypted email services (for instance, Gmail), you will be asked to enter a password that you will have to share with the recipient.  

The recipient will then use it to unlock your message and be able to read it by accessing a link. The URL will remain active until you send them another confidential email.  

This is what an email sent from a Tutanota account to someone who is using a different email service looks like.  

3. Hushmail

Hushmail is a secure email service based in Canada that encrypts your email communication. Simplicity is at the core of their business in order to keep their customers secure and better understand potential threats.

How you can increase your online security and privacy even more

Hopefully, I’ve helped you choose the best encrypted email service alternative to the risky email provider you are currently using. Yet, obviously, email anonymity does not equal online security.  

Even though some of the encrypted email services listed above also include spam filtering, virus scanning, or report phishing options, malicious attackers can always find ways to send you malware-infected links via email.  

This is why you should also be using a proactive, threat prevention solution for your PC, which lets you click any link with confidence and allows you to be sure that your endpoint won’t get affected by malware.  

And it scans and blocks the URLs you click both in your inbox and anywhere else on the web.

I used ProtonMail in the past – it was a good service but I having to think about if my recipients had PGP or knew how to set up keys was a pain. And the alternative of sending emails with passwords – that I then had to somehow share (often non-securely) doesn’t make much sense to me.
Anyway I’ve now settled with StayPrivate for my email encryption its easy to use and simple enough for everyone to use. I’ve been very happy with the service – still surprises me that they aren’t on these lists… It’s like my own little best kept secret! Ha but seriously if you looking for an easy to use encryption service StayPrivate is definitely worth a look!

I, for one, think this entire industry of encrypted email services is a scam. Nothing is 100 percent encrypted or anonymous when sent over the Internet. If any of these email providers is subpoenaed by someone with legal jurisdiction over them, they will have to comply with the subpoena, or face serious repercussions. It’s only a matter of the extent to which they would choose to be cooperative. And why would any company risk severe fines or imprisonment for protecting the anonymity of a suspected criminal?

Excellent article on the best secure email providers with their features. I’m using the RMail services for years, which provides the free plan and starts from $7 only.

RMail specializes in elegantly easy to use email encryption for privacy and compliance, e-signatures, legal e-delivery proof, secure file sharing, email impostor protection, document rights management, and AI-infused services to prevent data leaks and human e-security errors.

Does anyone know of software or service that would allow me to autorespond with an encrypted message?

What do you think about utopia? There is a future?

Protonmail is a theif. I paid a few months. Downgraded from paying to their free feature and gave up their vpn which I had paid. I left with ten days before my next payment charge. I left leaving them money. I left their free email because I was unsatisfied. I went to see the box and it had a mail stating I owed payment. A total lie. I have no trust in protonmail. They disliked the fact I used my freedom to down grade from pay to free and from free to exit. Protonmail is not worth my time.

An absolute joke. The EU is now scanning all private messages — emails, chat messages etc — so if you think the EU is the center of data privacy, you are very naive.

Avoid Hushmail at all costs. When they receive a civil subpoena, they neither fight it, nor inform you. And while the content of your messages may not be decrypted, they maintain a ton of IP addresses, geolocation, message subjects and more.

In short, you wind up with damned little privacy.

Its good to hear that another encrypted services about to launch but will it be more effective than regular like Gmail or Yahoo? and one more thing how you’ll beat them because both platform have huge as well strong hold in the market.
Thanks and Good Luck for the new one!

Protomail is only half as secure as it pretends to be!

I found several messages about Protonmail keeping IP-Logs and forwarding IP addresses to EU authorities and French authorities resulting in the arrest of several individuals!

Prontonmail does NOT deserve to be on this list, and for sure not as number ONE!

Protonmail scammed me. I paid for an upgrade but I still only get basic email. They can stuff their email service up their backsides

I prefer MeSign app anyway, free s/mime certs provided.

Lavabit anyone? Seriously. The founder of Lavabit has the most proven track record of NOT allowing access to logs, shut down the company before he allowed the FBI access, and then re-engineered the stack to plug that logging gap in the future. How can Lavabit NOT be on this list? I’ve been using it with absolute ease and peace.

Ah interesting…nowadays things that are put aside, not mentioned or banned are even more interesting Haha thanks for the tip I will check this out

FYI, Protonmail recently announced it is dropping support to the necessary bridge to Outlook & Thunderbird running on 32-bit operating systems. Now shopping for another secure email that is able to work with Outlook & Thunderbird on current 32-bit Windows operating systems.

I’m looking for the same, did you find one you can recommend?

Great to see email security being addressed here! For too long people have traded privacy for convenience and now it appears as though people understand there is a threat to privacy and are taking the initiative to be secure.
Best to everyone here, Darren Chaker

criptext is a useful email client for all platform,

How do you think about MeSince? A free email encryption email client with S/MIME standard. I think it is quite easy to use, they have a global public key DB, we don’t need to exchange the public key by ourselves. And every email will be encrypted, digitally signed automatically. I think it may worth to mention it and let people know.

What do you think about utopia? There is a future?
