Securing your emails is as crucial as your conversations and personal data. In fact, emails often include much more information about you. That’s why services like Tutanota Secure Email are gaining traction.

Especially, after Edward Snowden’s revelations about NSA’s surveillance program, the need to protect your privacy became the need of time.

Hence, Tutanota emerged as a secure email service that provides end-to-end encryption to the users. That, too, without any mandatory cost. Though, you can opt for their paid program to avail additional benefits.

Despite being an excellent service, and since it has been around for several years, Tutanota hasn’t created any hype in the internet world. Perhaps, you may not find any other Tutanota review explaining in detail about how to use it.

Nonetheless, as we strive to provide you with all the excellent privacy stuff, we share a detailed Tutanota guide for all first-time users.

What is Tutanota email?

Before getting your hands on the email service, let’s quickly review what Tutanota is all about.

Tutanota is a dedicated email service like traditional Gmail, Yahoo, and other providers. But what makes it different from others is its inherent security.

The name of the service itself is enough to hint at what it is. Derived from two Latin words – ‘tuta’ and ‘nota,’ which means ‘secure message,’ the name clearly shows that Tutanota is all about protecting your messages.

The service started off back in 2011 when the German firm Tutao GmbH launched it. Over the years, it established itself as a trusted app available as open-source. Hence, anyone can take a look at its code on GitHub to have insights about the service.

The service quickly gained traction among the users owing to its default end-to-end encryption. Just like a VPN encrypts all your network data, Tutanota encrypts all your emails. Thus, it saves your conversations from man-in-the-middle, spying, phishing, other cyberattacks, and surveillance by governments or ISPs.

What Makes Tutanota Distinct from Others?

If we talk about secure email services, then Tutanota isn’t the only one. There is fierce competition in the market, given that many usual email services also offer encryption. For instance, you can easily send encrypted messages via Gmail and Outlook, too.


Not to forget mentioning the rival ProtonMail that is used by many cybersecurity enthusiasts.

Nonetheless, Tutanota still manages to be in the lead owing to the following remarkable features.

Special email features

Managing your account

When you are using an online service, you need to know how to manage your account and profile settings.

In the case of Tutanota, the service provides various dedicated settings to let you choose how to send and receive emails.

You can find all the options by clicking on the gear icon at the bottom left of your screen. Here, the first option you will see will be your account settings. These include setting up your password, recovery code, and adding a two-factor authentication feature.

Also, scrolling down will show you the session history of the past two weeks. The service saves the information about the client and user IP address in encrypted form. Moreover, it deletes the session history after two weeks.

Managing email settings

Though, you may not have to meddle much with the account settings. Yet, you certainly need to learn about your email settings for a smooth experience in the future.

However, much of the settings here are only available to the paid users. For instance, if you want to apply rules to your inbox or add aliases, you need to subscribe to a paid package.

However, what you can still manage with a free Tutanota account is email encryption.

Just below your email account and sender name, you will see a feature ‘Default delivery.’ This is the feature that actually controls email encryption.

By default, it is set to ‘Confidential. It means every email you send to internal or external clients will be encrypted. As mentioned above, sending encrypted emails to external clients requires a password.

While you can turn off this feature individually before sending an email to an external client, you can also manage this feature through the given settings.

Simply set the default delivery status to ‘Not Confidential’. In this way, all external emails will be sent without end-to-end encryption in the future.

Though, the internal emails (Tutanota to Tutanota) will remain end-to-end encrypted.

Retrieving Tutanota block email

As Tutanota cares about user privacy, it not only offers encrypted messaging but also protects you from spams. Hence, it employs a robust security check on all incoming emails to filter out the malicious ones.

Such emails are not delivered to the users’ inbox. Rather Tutanota filters such emails and holds them onto their servers.

While the feature is good for privacy, it’s still possible that the service unintentionally blocks some emails vital to you.

Thus, it provides you with the settings ‘Rejected Emails’ that you will find in the ‘Global Settings’ menu.

Retrieve block emails in Tutanota

Here, clicking on this feature will let you check any Tutanota block email otherwise important to you. You can also whitelist the sender to receive future emails directly to your inbox.

Can I use Tutanota on Outlook?

Tutanota is a dedicated email service that offers end-to-end encryption within its own infrastructure. Hence, you cannot set up a Tutanota email on your Outlook app, because doing so will ruin the email encryption.

Also, you cannot adjust between Tutanota IMAP or POP3 settings, as it supports neither.

But it doesn’t mean that you are bound to use their web version. If you want to have Tutanota as your default ‘mailto’ client, you can download the Tutanota desktop client for it. Logging into the app will provide you with the same experience as you get with the web version alongside encryption.

How to delete a Tutanota account?

Though, Tutanota has the policy to delete free accounts that remain inactive for six months. Yet, if at any time you wish to stop using Tutanota, you can easily remove your account.

For this, you will find the ‘Delete Account’ at the bottom of the ‘Subscription’ menu.

Deleting Tutanota email account

However, be careful before deleting an account as Tutanota won’t allow registration with the same email address again in the future.

Tutanota vs ProtonMail

Tutanota isn’t the only service that provides end-to-end encryption. Shortly after its arrival to the online world, another service, ‘ProtonMail,’ emerged in 2013.

This Swiss service also advocates for user privacy while offering end-to-end encryption and zero-knowledge working. This makes it a tough decision for an average user to decide which service to use.

So, below we draw a quick comparison of the two services.

Encryption protocol

While both Tutanota and ProtonMail offer end-to-end encryption, the difference lies in the protocols they implement.

ProtonMail implements AES, RSA, along with OpenPGP cryptography. Their cryptographic libraries are all open source. And, they apply symmetric end-to-end encryption. This encryption applies to the email texts. However, ProtonMail does not encrypt email subject lines. Hence, part of your emails remains visible.

Whereas, Tutanota employs a combination of symmetric and asymmetric algorithms. Precisely, it uses AES-128-bit and RSA 2048-bit. Whereas, in case of emails to external clients, it applies AES-128-bit symmetric encryption. In the case of Tutanota, encryption applies to the entire content of your emails, including subject lines.

Moreover, Tutanota also applies bcrypt and SHA-256 hashes for securing passwords.


ProntonMail is basically a Swiss service based in the neutral zone of Switzerland. That makes ProtonMail pretty much desirable for privacy freaks as the territory isn’t bound to any sides by laws.

Tutanota, however, is based in Germany – one of the 14 Eyes regions. Nonetheless, it leverages the strict EU GDPR that prohibit uninformed collection of personal information.

Email import

Tutanota clearly does not support importing emails. It clearly mentions about this on its website.

Here, ProtonMail wins as it does support the import of emails. Also, it encrypts all the messages right after import. Hence, your emails remain secure.

Email to external clients

Both Tutanota and ProtonMail let the users send emails to external clients, such as Gmail, Outlook, and others.

Also, both of them support sending these emails with password-protected end-to-end encryption. But the difference lies in the way this encryption applies.

In the case of ProtonMail, users can choose the “Encrypt for Outside” feature to send encrypted emails. Nonetheless, as the service doesn’t encrypt subject lines and senders’ email addresses, part of the data remains visible, even to the other service providers.

Whereas, Tutanota warrants thorough security as it offers end-to-end encryption by default with thorough protection using U2F.

Wrapping up

So, this was all about using Tutanota Secure Email.

Certainly, for every privacy savvy internet user, Tutanota is an excellent option to use as their default email client. The service not only offers great security features but also supports all major devices with dedicated apps.

Although, as compared to ProtonMail, Tutanota’s interface may not be as interactive. Nonetheless, it’s easy to use, has clear-cut options, and offers numerous basic security features even for free users.

We hope this quick guide will prove to be helpful for you to get started with Tutanota. Nonetheless, if you face any difficulty at any step while using the service, feel free to write to us.
