Throwaway addresses are cheap for abusers and expensive for you.
One person spins up endless trial accounts with fresh throwaway inboxes, draining resources and skewing conversion.
Disposable addresses hide the identity behind a signup, a common first step in spam and abuse.
A temporary inbox is abandoned within minutes, so anything you send to it bounces or is never seen.
Every verification returns a disposable boolean alongside role and catch-all signals, so your code always knows what it is dealing with.
New throwaway services launch constantly. Our disposable domain list is maintained on an ongoing basis so detection stays accurate.

How disposable email detection works.
A disposable email address is a temporary, throwaway inbox from a service like a 10-minute-mail provider. People use them to sign up without revealing a real address, which makes them a common source of fake accounts and free-trial abuse.
Send an address to the API and it checks the domain against a continuously maintained list of disposable and temporary mail providers, alongside the rest of its 16-point engine. The response includes a clear disposable flag you can act on in code.
Yes. New throwaway services appear constantly, so the disposable domain list is updated continuously rather than shipped once and forgotten, which keeps detection accurate over time.
A disposable address is a temporary inbox meant to be abandoned. A role address (like info@ or sales@) is a shared, non-personal mailbox. A catch-all sits on a domain that accepts every address. The engine flags all three separately so you can apply different rules to each.
Call the API when the email field is submitted and reject or challenge the account if the disposable flag is true. For the full signup flow, including fake and mistyped addresses, see our email validation for signup forms page.
