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!

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.

Our privacy revolution

Big tech companies like Apple and Google use your personal information for their own profit. Now is the time to break free and take back what belongs to you: Your data. In 2011, long before the Snowden leaks, our founders Arne and Matthias knew of the dangers resulting from unlimited tracking and surveillance. They started working on Tutanota (now Tuta) to enable you to have a safe space, free from judgment and discrimination.
