Explore domain risk signals used by the RiskMail API

The RiskMail domain directory is a public reference for email domains we have classified. Every entry is one of two states: Temporary / Disposable (a known throwaway-mail provider) or Safe (a free public email provider, a regular business domain with valid mail infrastructure, or a domain we have not yet seen disposable signals for).

If you operate a signup or login flow, this list is a starting point — disposable providers come and go faster than any static list can track. The RiskMail API reflects the live database in real time and returns a clean verdict: disposable | safe for each request.

See something missing or misclassified? Tell us and we'll re-evaluate the domain.
