What is a Disposable Email Address?

A disposable email address (DEA), also known as a temporary email, throwaway email, or burner email, is a temporary email address that self-destructs after a short period. Users create these addresses to:

  • Sign up for services without revealing their real email
  • Avoid marketing emails and newsletters
  • Access gated content without commitment
  • Test websites and applications


Popular disposable email services include 10MinuteMail, Guerrilla Mail, Temp-Mail, Mailinator, and hundreds of others.
