ProtonMail alternative: Proton vs Tuta Mail

Proton and Tuta Mail are the two best known end-to-end encrypted email providers. This comparison of Tutanota vs Protonmail lets you decide which of the two secure email services is best to protect your private emails.

Key differences: ProtonMail vs Tuta Mail

In the digital age, data protection and security has become the top concern to many. Navigating the web securely is more important than ever, and secure email has become an indispensable tool. The solutions offering secure and easy-to-use email encryption are limited and in recent years ProtonMail and Tuta Mail have surfaced as the top choice of individuals and businesses to protect their online communication like emails, calendars and contacts. Thanks to the automatic encryption and user-friendly interfaces, these two private email providers are setting the standard.

ProtonMail describes itself as “Secure email with absolutely no compromises, brought to you by MIT and CERN scientists”; it is based in Switzerland and has about 100 million users. Many email providers claim to be good alternatives to ProtonMail, but only Tuta Mail is encrypted like Proton, making it ProtonMail’s number one rival. In fact Tuta Mail is better than ProtonMail as it encrypts far more data than Proton and has a stronger focus on protecting your privacy. All in all it’s the best ProtonMail alternative available. Tuta Mail is built in Germany, a country with some of the best data protection laws, has more than 10 million users and describes itself as “the world’s first end-to-end encrypted mail service that encrypts the entire mailbox. With its unique open source technology Tuta fights for privacy and freedom of speech online.”

Let’s find out which of the two is better, Proton Mail or Tuta Mail!

Encryption

Both Proton Mail and Tuta are privacy-focused email providers that offer end-to-end encryption for all emails. Both enable users to use a password for encrypting emails sent to recipients that don’t have an email address with an encrypted email provider. One major differentiation here is that in Tuta Mail external recipients can access the entire email thread via the shared password while recipients of encrypted messages from its rival Proton Mail are limited to just seeing one message.

In addition, there are quite important differences in the encryption methods used. ProtonMail uses PGP encryption, which lacks important requirements that Tuta is able to fix. Tuta Mail encrypts not just bodies and attachments of emails like it is done with PGP, but also the subject line, which can contain very sensitive information. Additionally, the encryption protocols used in Tuta enable us to easily upgrade to new quantum-secure algorithms and add support for Prefect Forward Secrecy.

Instead of using an implementation of PGP itself, Tuta uses standard algorithms also being used by PGP (AES 256 / RSA 2048) for encrypting not just emails, but also other information that ProtonMail does not encrypt such as the entire address book and calendar metadata like calendar notifications. Tuta is the only email service that automatically encrypts all this data.

Security

Tuta and Proton Mail both prioritize user security and privacy over profits, unlike older generation free email providers like Gmail, Yahoo Mail and Outlook. People choose to create email addresses with these two private services to get rid of Big Tech tracking and personalized ads. Tuta excels in this regard as it pays more attention to the details, particularly when it comes to privacy-first solutions. For instance, Proton email uses some integrations with closed-source third-party services, including Google push notifications while we’ve developed our own open-source alternative to reCAPTCHA and we’ve published our Android app on F-Droid, making it one of the few email apps available with NO ties to Google services. You can be sure that the Tuta Android app does not include Google’s Analytics tracking code.

Both Tuta Mail and Proton Mail offer open source email clients, which means that anyone can inspect the code and ensure there are no backdoors. Tuta takes this transparency even further by also offering free open source desktop clients for Linux, macOS and Windows while Proton has built a so called "bridge" only available to paying users. However, such a bridge is not a solution because at Tuta we aim for the highest security level:

  • By using the Proton Mail bridge all data is stored unencrypted in the third party email client. We at Tuta Mail aim for a solution where all data is always stored securely encrypted, even on your own devices. Our desktop clients do exactly that and make the data also available when offline.

  • The protocols IMAP and SMTP used by the Bridge are not the most efficient protocols especially when it comes to push notifications or to attachments of emails (which are encoded into the body).

  • With improving our Tuta Mail desktop clients we serve you much better than by spending time in developing and maintaining three bridges for Linux, Windows and macOS.

ProtonMail and Tuta use secure servers located in Europe (in Switzerland and Germany, respectively), but Proton have secondary offices in the US, one of the Five Eyes countries.

Business features

Tuta and ProtonMail both offer business-focused plans, with secure business email and calendar, multiple custom email domains, multiple alias addresses and inbox rules. Only Tuta allows you to create an unlimited number of custom domain email addresses, have an unlimited number of fully encrypted calendars and a plan with a whitelabel version, while only Proton email business plans include a VPN service.

Sustainability & Green Email

While ProtonMail doesn’t have any sustainability initiative as of yet, Tuta uses 100% renewable electricity for all its servers as well as its offices. A private, secure and encrypted email service that is also the most free and sustainable option is a choice you can feel good about!

Pricing

The real difference between Proton vs Tuta Mail becomes obvious when looking at features within each plan: Both Tuta and Proton Mail operate on a freemium model, offering free and paid versions of their email service. Tuta paid plans are more affordable than ProtonMail's with more features included.

In Tuta's Revolutionary plan you get 20 GB of storage, 3 custom domains, 30 email addresses and an unlimited number of custom domain email addresses while in Proton's Mail Plus plan you get 15 GB of storage, 1 custom domain and 10 email addresses. The Tuta free version includes 1 GB of storage, while Proton's free version includes 500 MB of storage.

TutaMail stands out for its use of AES and RSA encryption, which encrypts email metadata such as subject lines, and is planning to update its algorithm to achieve post-quantum secure encryption in the near future. In terms of sustainability, Tuta relies exclusively on sustainable electricity. We offer more features than Proton Mail with our free email accounts and have lower prices for our paid plans with more features included.

Tuta is more than just email: Beyond the encrypted email service, Tuta Mail also offers a fully encrypted calendar for all devices regardless whether you choose to create a free or paid account. These calendars are secured with end-to-end encryption and can be shared with your friends and loved ones easily.

Tuta gives you the best encrypted organizational tools available on all clients: Android, iOS, Windows, macOS and Linux. Plus, we plan to launch an encrypted cloud storage solution Tuta Drive that will also use post-quantum cryptography to secure your files, images, and other data.

When choosing TutaMail, you get the biggest bang for your buck compared to ProtonMail! You can enjoy end-to-end encrypted email with an unlimited number of custom domain email addresses, fully encrypted calendars and business email features all in one. On top of that Tuta offers its own open source desktop clients that always keep your data securely encrypted and available locally, even when offline.

Switch now and simply forward your emails to Tuta!

To create a new free email address, register your personal Tuta email address now.

Unfortunately, if you are currently using a Protonmail email address, you will not be able to set up auto forwarding as this feature is not available in Proton Mail.

This means that you need to forward important emails manually on a daily basis for a couple of weeks. You can then inform each sender about your new email address so that they will start sending to your Tuta address directly. When you have the feeling that no more important emails are being received at Protonmail, you can leave this account dormant and occasionally check whether an important email has still landed in your Proton account.

This way, you will have a much cleaner inbox and get rid of all the unwanted newsletters that have accumulated over the last couple of years.
