Be aware that the .us.to and .uk.to domains or any other that's run by afraid.org have known issues. Afraid/FreeDNS sucks when it comes to supporting their domains properly, and you're likely going to run into weird issues like email not delivering and Lets Encrypt claiming its rate limited when it shouldn't be (the most commonly reported issue I see with these domains).
These issues aren't HelioHost's fault, but rather that of Afraid, and most hosting companies exhibit some odd behaviors with their domains.
For basic HTTP they're fine I suppose...
