We used them for more than a year now for mail and calendar.

Works fine, it’s stable and easy to use. Even non-technical persons can receive password encrypted mails from you.

Beware that their support is not that bad but definitely slow.

It‘s a centralized service from Germany so expect a backdoor or all your transferred data easily available for governments. Like 99,9 % of all the network-data.

They are banned in multiple countries, very good sign they actually live up to the hype

I think that it does its job, but index/search is total ass. Also, it takes a while to sync if you haven't opened it in a while. The fact that they charge you for extra aliases is dumb, considering that Gmail can do username+extrawordalias@gmail.com.

Very good value for money, but the Android client could be better...

Never used it, so I cannot express an opinion on the specific service, but I'm not so enthusiastic about e2e email services, because they usually break the standard email protocol. E.g. from https://tuta.com/support

> Can I retrieve my Tuta emails via IMAP to another email client?

> This is not possible as we could not guarantee end-to-end encryption for your data. Instead, Tuta offers email desktop clients for Linux, Mac OS and Windows as well as a web client and apps for Android and iOS.

Then the encryption benefit applies only if both parts use it, otherwise Tuta can always read the correspondence.

If i need it, I prefer to manage the encryption on a second independent layer, e.g. GPG or a basic but effective ZIP with password :)

They made some blog posts about American politics in the past they really turned me off. Gave me the impression that if they don’t like your politics, they wouldn’t hesitate to mess with the account or just close your service.

ProtonMail isn’t much better btw.
