FEATURES
Four clear results
for every email
Every address you check gets one of four results.
Valid
The mail server accepted the address when we checked, so it is capable of receiving mail.
Invalid
The address cannot receive mail: the domain has no mail setup, or the server said the mailbox does not exist.
Catch-All
The domain accepts mail for any address, so we cannot tell whether this particular mailbox exists.
Unknown
We could not get a reliable answer, for example because the server was busy, slow, or blocking checks.
Bulk or single checks
Check one email or a whole list. Upload a CSV, TXT, or XLSX file, or paste your emails.
