Email verifier
Check whether an email address exists and can receive mail — before a bounce hurts your sender reputation.
How verification works
We check the address is written correctly, that its domain has mail servers, then ask the mail server whether the mailbox exists — without sending an email.
Some domains accept every address (catch-all), so a single mailbox can't be confirmed. DoReach can resolve those in bulk by sending a real probe.
Got a whole list?
Upload a CSV to DoReach and verify every address at once, then download only the good ones.
