    Classify the domain of an email address or a bare domain as disposable, free (e.g. Gmail), alias (privacy relay), testing, parked or unknown, with the reason, evidence and whether it can receive mail. Use before creating an account or sending a verification email. Unknown means not enough evidence, not safe.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
