Find out instantly whether an email address uses a temporary, throwaway or burner domain. Keep fake signups out of your lists. Free, no signup.
A disposable email address — also called a temporary, throwaway or burner address — is created to receive mail for a short period and then abandoned. Services such as Mailinator, Guerrilla Mail and 10 Minute Mail hand out these addresses so people can sign up for things without exposing a real inbox. The address often stops working within minutes or hours.
While convenient for users, disposable addresses are a problem for anyone collecting emails. They inflate your list with contacts who will never open, click or buy, push up your bounce rate, and can drag down the sender reputation that determines whether your real subscribers see your mail at all.
Checking addresses one at a time is useful for spot checks, but to stop disposable signups in real time you need automated protection. ClearBounce Shield blocks disposable, invalid and risky emails directly on your signup and checkout forms, and bulk verification removes them from lists you already have — both include disposable detection out of the box.
