Mister.T.Rev ,

Great service for E2E encryption.

I still use the free service and its fantastic. I could certainly use the added features of a paid plan, and its not expensive. I just cant do it. I still use other free services for normal email but when it comes to personal data or login/password confirmation, Tutanota is the only way to go. If I could setup the account to remove sensitive data and forward to my gmail I would have the perfect setup. Probably could with a paid plan, but having to use their client is a small price to pay for peace of mind. And that they are doing the tech heavy-lifting saves me time and resources

Thanks again for providing one of the truely top notch free internet services.

Excellent App

I have been a paying customer for 4 years now. I joined after my privacy came into question with another service. There are so many benefits to this service it is incredible. Sure, services like this can be really frustrating for people that don’t understand their uses, but it is worth it when you really want some privacy.

The app itself is great on the whole. Pinching would be nice to blow up/shrink text, but that is minor to me. It would be nice to have the “Save credentials” checkbox farther away from the login, but again, this is minor.

For me, there are three things that would make this service itself second to none for years into the future. These are nit-picky because I know they are working through post quantum encryption. First, give the ability to have all incoming messages converted to plain text; yes, I understand that this may cause us to lose some content, but that may be worth it, especially late at night in the comfort of my bed. Second, give the ability to set a mono space font as default and the ability to use colored/highlighted text; the lack of coloring/highlighting can be a major inconvenience when I really need it. And third, the ability to send a self-destructing message. I don’t need it often, but an encrypted message that I know can then be destroyed would be the best piece of mind.

The app is very comprehensive and extremely easy to used and work’s fantastic i have had zero problems while using it and there has been no trouble receiving or sending emails but what i really want to share is the service itself they have been absolutely amazing they are always quick to respond and have had perfect customer service even when i was late on my payment they were quick to email me and ask what was going on and it wasnt some machine sending a automated message either like most services “pay us money or else” i explained the situation and they were happy to help i asked for a small extension due to some emergencies that had happened and they agreed no problem i would recommend this service to anyone who needs a secure private email or really anyone who needs a email service in general if you are out there and you have some gmail account and dont mind spending a few bucks a month then due yourself a favor and switch over because its worth every penny and you wont have to deal with the typical nonsensical bull that most services put people through i love this service THANKS TUTANOTA! Keep being awesome
