What is a Disposable Email Address?

A disposable email address (also called a temporary email, throwaway email, or temp mail) is a short-lived email address you can use instead of your real one.

How does it work?

Unlike traditional email providers (Gmail, Outlook), disposable email services:

  • Require no registration — you get an address instantly
  • Auto-expire — the address stops working after a set time (10 minutes on tempy.email)
  • Leave no trace — emails are deleted when the address expires

Common use cases

Signing up for websites

Many websites require email verification. Use a disposable address to verify your account without exposing your real email.

Avoiding spam

Give your temp address to services you don't fully trust. Any spam they send goes to a mailbox that will cease to exist.

Testing and development

Developers use disposable email to test email-sending features in their applications without needing multiple real accounts.

Yes. Using a disposable email address is completely legal. It's a privacy tool, no different from using a PO box instead of your home address.
