What Are Disposable Email Addresses?

Disposable (or temporary) email addresses are created from services like Guerrilla Mail, Temp Mail, and Mailinator. They expire after minutes or hours. Users create them to bypass signups, abuse free trials, or hide their identity.

Why Block Disposable Emails?

Disposable emails lead to fake signups, trial abuse, and wasted resources. By detecting them at registration, you keep your user base genuine and protect your platform from fraud. MailCheck maintains a database of 5,000+ disposable domains, updated regularly.
