Disposable Email Address

Also known as: Temporary Email, Throwaway Email

A short-lived email address from a temporary-mail service, used to avoid giving out a real address.

A disposable email address (DEA) is a temporary inbox from services like Mailinator, Guerrilla Mail, or 10MinuteMail. People use them to grab a download, claim a coupon, or sign up without exposing their real address — the inbox is discarded within minutes or hours.

For a sender, disposable addresses are almost pure cost. They will never convert, they inflate your list size, and they often bounce soon after the temporary inbox expires. Detecting them is mostly a matter of recognising the thousands of known disposable domains.

BounceShift checks every address against a continuously updated list of disposable domains (plus an extra in-house list) and flags them so they never enter your sending list at signup.
