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.
I specifically chose a shared hosting situation so they deal with the issues in this case. I do have a VPS and could have placed it there but I did not want the hassle and it is not something my wife could manage if something ever happened to me.
As far as unlimited, they do have such a plan but I do not need it. 30 is infinite in my case.
