Better name that TUTANOTA
To increase product marketing please change TUTANOTA to something else. It does not sound as business solution. It has to be simple and marketable.
My ideas to call the service:
"Clear" "Poster" "Mailer" "Chatter" "Privateer" "Enforcer" , something that serious businesses would be inclined to use from the derivation of the name
We like Tutanota :)
The name Tutanota is good and the derivative directly from Latin appeals to me at least.
The "Tutanota" business has spread its wings to all manner of different types of people around the world and may include "serious businesses" as well, whatever that may happen to be.
Various people that I have spoken to, admittedly creative, jouranlistic and activist types, would probably be less inclined to use the service with a generic sounding name such as "Enforcer" etc or if the service was geared to "serious businesses" but if you are a "serious business" then there are other "business solutions" which would no doubt suit it.
