Control of the tech stack: Tuta vs. Mailbox

Many email services, even secure ones, use third-party tech like Dovecot, Roundcube and others to build their own products. Every time a so called secure service uses third-party applications, it becomes more difficult to secure said service. The reason is simple: Every service included in the code executes code. Any services' security can't get better than that of its dependencies. Every dependency to third party code must be maintained and security updates need to be applied immediately. In addition, every third-party service can potentially track the users, send data to its own servers etc. That's why we at Tuta only use open source code that we have vested ourselves before using it. This way we make sure ourselves that the open source tools Tuta does use are secure: We regularly run security reviews of these tools as well as of our own clients, for instance when we pushed our desktop clients out of beta.

Of course, we at Tuta can't re-invent the wheel either. But we have built our entire clients - web, Android, iOS, and all desktop clients - on our own. Plus, we have a strong focus on security in our whole development workflow. All developers share the same DNA: privacy and security first.

One main differentiation of Tuta is that we build all major parts of Tuta ourselves, even outside of the core email functionality such as our captcha, our push notification service on Android and more.

Only with open source - of our own clients and of the software that Tuta depends on - tech-savvy people can audit the code and verify that Tuta is doing what we promise: Securing your private emails to the maximum.

Check here why we recommend to choose our secure desktop clients for Linux, Windows and macOS and why it is so important that we have built our own open source captcha as well as an alternative to Google Push on Android.

A better web

Secure

Tuta automatically encrypts all your data end-to-end with post-quantum cryptography which makes it the safest email provider.

This is hands down the best free privacy oriented email service out there. They genuinely care about the end users privacy. The data they collect is next to nothing (if any) and provide a plethora of amazing services.

BRYCEN GUNTER

Secure email and a secure calendar. I didn't need 20gb of space but I wanted to pay to support this company. I also enjoyed the ability to have custom domain integration.

CHRIS L McCLISH

Best secure Email provider! Love this provider! I've been a happy customer for a while now. I have even recommended this to relatives. No worrying about privacy infringement or identity/data security. I can rest assured that my emails remain private.

TRISH

For this Android user, this secure email client is one of the best available out there. I like having the calendar, email and contacts combined in one app rather than multiple places. Great app for those important emails and events.

Green

We take our responsibility seriously and only use renewable energy to power your emails, calendars, and contacts.

Thanks for being a solid company, I'm very happy to have switched from proton since Tuta handles several things (green energy, fdroid app, linux app) way better.

JEREMIAH

Uses 100% renewable energies, open source, supports non-profits and schools, respects privacy, ad-free. Also offers nice phone and laptop apps. Just switched to a paid account to support the company though the free version is really good already on its own (I've used it for a year now). Definitely five stars!

TARKAN SCHNEIDER

Ad-free

We give you the freedom to communicate confidentially, without any tracking or personalized ads.

It works very well and you are not bombarded with intrusive and harmful advertising. A most excellent replacement for all Microsoft and Google email accounts!

ANONYMOUS

Secure and private with encryption, ad free and free, what's not to like.

GRIMEST

Tuta is the best cost-benefit email service in the market. It has the same main features as most mail providers. The difference is that Tuta cares about your privacy and won't use your data against you, nor try to convince you to click on ads selling stuff you don't need.

FERNANDO SILVA

With the big tech companies scanning and using your email as a way to push advertisements, it's comforting to use something secure and, for lack of a better word, cool. You use email a lot right? You out also know that free isn't really free, the price is for tech companies to get your info. I love Tuta.

CHRIS L McCLISH

I use Tuta 2 weeks now and I didn't find something to keep me away. Black beautiful GUI, easy to navigate throughout app, encrypted messages with password, even the login has 2FA, there is no ads.

Tuta - the email alternative that respects your right to privacy.

With its all-round end-to-end encryption and its clear focus on open source, Tuta is the best email provider when it comes to convenience, security and privacy. We have replaced the need for IMAP by building the Tuta desktop clients for Windows, Linux and Mac OS that also support offline mode. Our next development steps include conversation view and email import. Our vision with Tuta is to become a full-fledged email alternative with a calendar, notes, cloud storage - everything encrypted by default.
