This online email verifier checks format, domain MX records, and attempts an SMTP handshake to see whether the mailbox can receive mail. Enter an address and click "Check email" to get a result.
It is useful for cleaning mailing lists, reducing bounces, and validating sign‑ups. Some mail servers do not reveal recipient status, so the result may be "Unable to determine" even if the address is real.
No messages are sent and nothing is stored. The check runs in the browser and completes in seconds.
