Frequently refreshed domain data

Disposable email checker

Check whether an address is tied to a known temporary or throwaway email provider.

What is a disposable email address?

Disposable email services provide temporary inboxes that can be used for one-time registrations or short-lived messages. They can be technically deliverable while still being poor-quality addresses for accounts, CRMs or mailing lists.

How this checker works

EmailValidly checks the submitted domain against a large community-maintained disposable-domain blocklist loaded into the production verifier and refreshed periodically. A domain not appearing in the list is not a guarantee that it will never behave like a temporary-email service, but known disposable providers are flagged immediately.
