Questions & Answers

As answered by people managing CustomDomain.ai and StackMail.

What makes your product unique?

CustomDomain.ai's answer

Two things.

First, your users never handle DNS themselves and never hand you credentials. They click once, sign in to their own DNS host over OAuth or Domain Connect rails, and the grant is used once and discarded. We fingerprint the provider from public records, write the exact A, CNAME and TXT records, verify them end to end, and issue the certificate before the first request.

Second, it does not stop at connection. We re-check every domain every hour and re-issue on change, so you hear about a moved or deleted record before your customer does. Most integrations treat a domain as done once it resolves; domains drift.

It is also optional at the edge: serve customer domains from our edge, or verify and hand DNS straight back to your own stack. And there is an MCP server, so AI agents can connect domains the same way your UI does.
