What is Temp Mail?

Temp Mail is a life-saver in the modern internet era. Every time you sign up for a new service, you are forced to provide your email address. This often leads to an inbox full of spam. Our privacy-first disposable email solves this.

A zero-disk temporary email address allows you to bypass these requirements safely. Receive your confirmation links instantly in real-time, and then discard the address. Keep your real inbox clean.

Zero-Disk Privacy

Your emails are never written to disk. We use a privacy-first, 100% RAM-based architecture for maximum security.
