How large is your disposable domain list?

We track over 150,000 known disposable, temporary, and 10-minute email domains. This list is updated continuously as new burner domains are registered and detected in the wild.

Are freemail providers (like Gmail) blocked?

No. Providers like Gmail, Outlook, and Yahoo are classified as 'freemail', which is tracked as a separate flag from 'disposable' domains. You can choose to block freemail if you only want B2B signups, but they are not considered disposable.

How fast is the lookup?

The API evaluates the domain directly from our in-memory edge cache, consistently returning a verdict in single-digit milliseconds, ensuring zero friction in your signup flow.

What happens if a legitimate domain is blocked?

False positives are extremely rare, but if a legitimate corporate domain is flagged, you can whitelist it in your application logic or report it to us for immediate correction.

Does this API send an email to verify the address?

No. This is a passive verification check that analyzes the domain name against our intelligence databases. It does not send any emails or perform SMTP handshakes.

Can I use this on the frontend?

While possible, we strongly recommend implementing this API on your backend to protect your API key and ensure validation cannot be bypassed by malicious users modifying client-side code.
