Free email verifier
Instantly check a single email address. No account, no card - just type an address and see whether it’s safe to send to.
What the result means
Valid
Confirmed at the mailbox level: the address exists and accepts mail. Safe to send.
Invalid
Bad syntax, no mail server, or the mailbox does not exist. Remove these to stop hard bounces.
Catch-all
The domain accepts mail for any address, so no provider can confirm the exact mailbox from outside. We flag these separately and give you a "valid + catch-all" export, so you decide whether to send.
Disposable
Temporary or throwaway inboxes from known disposable providers. Usually worth removing.
Unknown
The mail server wouldn't give a clear answer, usually greylisting or a timeout. Never charged to your account.
