Disposable email addresses let users create temporary inboxes that self-destruct. Learn why people use them, how they impact your business, and strategies for detection and handling.

What Are Disposable Email Addresses?

Disposable email addresses (DEAs), also called temporary or throwaway emails, are email addresses that expire after a set time or number of uses. Users create them instantly without registration, use them for a single purpose, then abandon them.

Popular Disposable Email Services

Hundreds of services offer disposable emails including 10MinuteMail, Guerrilla Mail, Temp-Mail, Mailinator, and ThrowAwayMail. New services appear constantly, making detection an ongoing challenge.
