FAQ
- What is a disposable email address?
- A throwaway or temporary inbox (Mailinator, Guerrilla Mail, 10MinuteMail, YOPmail and similar) that anyone can use to receive a message without signing up, often used to skip verification, abuse free trials, or hide identity.
- How accurate is this checker?
- It matches the domain against a large, curated blocklist of known disposable services, including subdomains. New throwaway domains appear constantly, so a “looks OK” result is not a guarantee, it means the domain is not on the list.
- Is my email address sent anywhere?
- No. The blocklist is downloaded once and the lookup runs entirely in your browser. The address you type never leaves your device.
