Disposable email checker

Check if an email uses a disposable or temporary domain

Paste one address, a CSV export, or a list of domains to find common temp-mail services like mailinator.com, yopmail.com, guerrillamail.com, and 10minutemail.com before accepting signups or importing leads.

Check emails or domains

The watchlist check runs in your browser against 55 common temporary, throwaway, and alias-style domains. Use Verifly verification for mailbox, catch-all, and deliverability signals.

Disposable detection is one layer

A domain can pass this watchlist check and still bounce, reject mail, or behave as catch-all. Use Verifly for mailbox-level verification before sending or importing a list.
