Here's what I found with a little research. From https://tutanota.com/:

> Tutanota automatically encrypts all your data on your device. Your emails as well as your contacts stay private. You can easily communicate with any of your friends end-to-end encrypted. Even subject and attachments are encrypted.

It might have been better to submit a different blog post or web page which might have provided more context. Or the submitter could have left a comment about what Tutanota is to provide the extra context.

Note that I don't really mean to single out this submitter, this seems to be a common problem. It's probably also worth pointing out that posts on official company blogs should not assume that readers of any one blog post are regular readers of the blog.

Edit: As an addendum, I should probably point out that I agree with rossjudson's comment to which I am replying.

I upvoted him because I could see the problem immediately. There were a lot things said but with little real information for comparison to other things. Had to dig around the site a bit before that. A number of these new offerings have this problem. Compare to this product [1] where I know at a glance exactly what the thing does with enough specifics to begin mental comparisons and know what its likely strengths/weaknesses are. Anyone doing reviews would benefit if the new stuff was that clear at a glance.

Note: Not endorsing the above product. It was search result with good description.

Agreed, that was my reaction as well. I suppose that's the tradeoff of a descriptive name for your project.

The title originally submitted here was more descriptive before it got changed to the text of the heading from the blog post in the link. Regular readers of the Tutanota blog will presumably already be aware of what it is, by virtue of being regular readers of the Tutanota blog.
