About temporary emails
Temporary email addresses — from "10-minute mail" and burner services — give a self-destructing inbox that expires minutes or hours after creation. People use them to grab a trial, coupon or download without handing over a real address, then the mailbox vanishes.
Any address you collect that is temporary is effectively dead on arrival: follow-up mail bounces and the "contact" never converts. This detector matches addresses against known temporary-mail domains so you can block them at sign-up or strip them from an existing list. As new services appear constantly, re-screen periodically for the best coverage.

Got Questions? We Have Answers.
What is a temporary email?
An address from a burner or "10-minute mail" service that expires minutes or hours after creation, used to grab a trial or download without a real inbox.
How is this different from disposable detection?
They overlap heavily — temporary mail is a form of disposable mail. This tool frames the check around short-lived, self-destructing inboxes specifically.
Why block temporary addresses?
They are dead on arrival: follow-up mail bounces and the contact never converts, so they only inflate your list and bounce rate.
Can I check a whole list?
Yes. Paste one address or many; the tool splits temporary from permanent addresses for you to copy.
