Disposable Domain List

Updated daily · 20,000+ domains tracked

We maintain a publicly accessible list of disposable email domains — domains used by temporary email services like Mailinator, Guerrilla Mail, and 10-minute-mail. The list is updated daily as new throwaway services appear.

You can reference this list to block disposable signups, build custom verification workflows, or audit your existing subscriber base. The dataset is available as a plain-text file or through the OpenGuardian API.

OpenGuardianu2019s verification API checks every email against this list automatically — plus runs syntax, MX, SMTP, role-based, and spam-trap checks — and returns a verdict in under 300ms.
