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.
They front a huge percentage of the internet, so you can pretty much guarantee that all of the three-letter agencies have their fingers in Cloudflare’s infrastructure, whether they cooperate willingly or not.
If you care about your privacy you should avoid these kind of infrastructure monopolies, since they are such a juicy target.
