What it does

Match domains against a continuously updated disposable list.
Flag temporary and throwaway providers.
Block them at signup with the API.

Why it matters

Disposable addresses self-destruct and never convert. Detecting them keeps your list clean and your engagement metrics honest, especially when paired with real-time form verification.

Disposable signups exist to grab a lead magnet or trial without giving a real address, so they inflate your numbers and never convert. Catching them — at the form or in a bulk clean — keeps your engagement metrics honest.

Questions

Frequently asked

How do you detect disposable domains?

We match against a continuously updated list of known temporary-email providers, combined with other risk signals, since new disposable domains appear constantly.

Can I block them at signup?

Yes — the API rejects disposable domains in real time so they never become a record.

Are all throwaways caught?

We catch the large known set; full verification pairs this with deliverability checks to reduce what slips through.

Stop wasting hours on dead leads.
