Free disposable email checker
Check whether an email address or domain belongs to a temp-mail / disposable provider. Our list covers 484+ of the most common throwaway services like Mailinator, 10MinuteMail, Guerrilla Mail, and Yopmail.
Why disposable emails matter
Disposable addresses are used to bypass signup walls, claim free trials, or hide identity. They're real mailboxes — the SMTP check will pass — but they expire in minutes to hours. Sending to them wastes spend and skews funnel metrics.
How we maintain the list
We track public disposable-domain lists curated by the open-source email-validation community. New providers appear constantly; if you spot one we miss, please tell us.
Want to filter a whole list at once?
The bulk email verifier automatically flags disposable, role, and catch-all addresses across CSVs up to 10,000 rows.
Need to verify 10,000 emails at once?
Bulk email verifier checks every address against the real mailbox, rescues catch-alls, and returns a clean CSV. No subscription — pay per credit, with auto-refunds on uncertain results.
