What Is a Burner Email?
A burner email is a disposable email address used for short-term tasks like OTP verification, free trial signup, and one-time content unlocks.
How Burner Email Works Behind the Scenes
- A random address is generated instantly (for example, abc123@domain.com).
- Incoming emails are routed via MX records to a catch-all inbox.
- The app filters messages by recipient and shows only your inbox.
- Messages auto-expire after a short retention window.
