The simple definition
A temporary email address — also called a disposable email, throwaway email, or burner email — is a real, working inbox you use once, then let expire. Unlike gmail.com or outlook.com, a temporary address has a built-in expiry timer. When the timer runs out, the address stops receiving mail and every message ever delivered to it is permanently deleted from the server.
How is it different from a regular inbox?
The key difference is traceability. A regular inbox is linked to your name, phone number, date of birth, and real identity. Every company you give it to can add you to marketing lists, sell your details to data brokers, and expose your information in a breach. A temporary address carries none of that. There is no name attached, no password to recover, and no permanent account to manage.
How does it actually work?
Temp Mail operates a real mail server with DNS MX records pointing to it for all supported domains. When you click Generate, a new address is registered on that server. Any website can send standard SMTP email to it — exactly as they would to Gmail. When a message arrives, you see it in your inbox within seconds via Server-Sent Events. When the address expires, a cleanup job permanently deletes the address and all its messages.

Is it legal?
Yes. Using a disposable email address is completely legal in virtually every country. It is simply a privacy tool — no different in principle from using a PO box instead of your home address for physical mail. There is nothing unlawful about protecting your inbox.
