I already use Tuta as my email provider. I already have a domain I can use with it (bought privately). What privacy implemcations does it come with.
The main reason is because I would like to be able to keep the same email address for longer and not have to change when/if I change providers.
For domain registration? I don’t see much of an issue. I also use their DNS services, but not caching or proxying or anything that would allow them access to any data in flight or info on connections to my servers or anything like that. I’m not trying to be anonymous, though, just private.
