This is the most secure email and calendar software that I've been able to find. they have super fast support that got me out of a big jam. Their paid tiers are well worth the money.

MARC DONI

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

A fantastic app! Privacy is paramount with emails, contacts, and calendar information, which isn't used for advertising. I highly recommend it! The team is available and responsive to any issues, should they arise. Go for it without hesitation!

RAPHAËL CAUHÉPÉ-FRANÇOIS

It's hard to find a service that appeals to both privacy nerds and people who just need to get through their inbox asap, but they've nailed it. My data feels safer and the price is reasonable. I'd love to see them add an encrypted meetings feature in the future. Definitely worth the switch, don't think twice.

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, F-Droid app, Linux app) way better.

JEREMIAH

Green, genuinely cares about open source, and great service. Tuta doesn't depend on Google services at all, unlike others (Proton)

JERRY

Uses 100% renewable energy, 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

A good alternative to the big players like Google/Microsoft if you care about privacy and want something more European.

OLAF VAN DE BELT

Thank you for respecting our privacy, at the same time thanks for being a green energy company.

I formerly used Gmail for many years till I just got sick and tired of all the spam and ads. I've been using Tuta for around a year now, and not once have I received spam nor an intrusive ad. Tuta's free plan comes with plenty of space for the average person, and the app is incredibly easy to use. 100% recommend!

KIERAN LEE

Exactly what I was looking for. Independent of Big Tech. Great email program.

NORBERT

Why do I like it? Because the interface is simple and ad-free.

LAURENT OUTAN

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 ought also know that free isn't really free, the price is for tech companies to get your info. I love Tuta.

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.
