Disposable Email Detector

What it does

Disposable Email Detector checks an email address and returns signals you can use to decide whether it looks temporary or risky. Send an email in the request body, and get back a confidence_score plus a set of detection signals for the domain.

Use the returned signals to inspect whether the domain appears on a blocklist, whether it has disposable_mx characteristics, whether it has has_mx_records, and how old the domain is in domain_age_days. The response also includes an entropy_score for the domain label, which can help flag randomly generated or low-quality domains.

This is useful when you want to reduce fake signups, filter throwaway addresses in lead capture forms, or add an extra risk check before sending account verification or marketing email. Keep your own policy on top of the score: a single signal may not be enough, but the combined confidence_score gives you a compact disposable-email assessment.

If you need a fast validation step in a signup, onboarding, or abuse-prevention flow, Disposable Email Detector gives you structured signals without forcing you to inspect DNS and registration data yourself.
