Disposable email addresses (also called temporary emails, throwaway emails, or burner emails) are email accounts that self-destruct after a certain period. They are commonly used to avoid spam when signing up for websites, but they are also frequently abused for fake registrations, spam, and fraudulent activities.

Popular disposable email providers include Mailinator, Guerrilla Mail, 10 Minute Mail, TempMail, TrashMail, and YopMail. These services allow anyone to create an email address instantly without registration, making them a common tool for bypassing email verification systems.

By checking email addresses against our comprehensive database of known disposable domains, you can prevent fake signups, reduce spam, and improve the quality of your user base.
