A burner email is a throwaway email address you use for a single purpose — then discard when you're done. Unlike your real inbox, a burner email address keeps spam, marketing lists, and data brokers completely away from your personal account. BurnerInbox creates one for you in seconds, free of charge.
The term "burner" comes from burner phones — disposable devices with no personal ties. A burner email works the same way: it's a temporary email tied to nothing real. You generate one, use it, and walk away. No consequences, no spam trail.
This is the #1 use case in 2026. Platforms like ChatGPT, Google Gemini, and Midjourney limit their free tier to one account per email address. With BurnerInbox, you can generate a fresh burner email for AI tools whenever you need one — unlocking new free credits, new trial periods, and new accounts without paying.

None in practice. A throwaway email address and a burner email are two names for the same thing. You might also see it called a disposable email address, temp email, or trash mail.
