Questions
Can I move from SimpleLogin to HiddenAt?
Yes. Add your domain to HiddenAt and point its MX record at HiddenAt; every address at the domain then forwards to your inbox. Replies from aliases aren't supported, so check you don't rely on them first.
Is SimpleLogin cheaper?
For one domain, HiddenAt costs less: $2.99 vs $4 a month, or $29.99 vs $36 a year. If you use several domains, SimpleLogin Premium works out cheaper because one price covers unlimited domains.
