How we check if an email address is real

Every step reads public records. We never send a test email to the address.

  1. Check the format

    Catch typos like a missing dot or a doubled @ before anything else.

  2. Look up the mail servers

    A domain with no mail servers cannot receive anything, however real it looks.

  3. Flag the risks

    Disposable services, shared inboxes, and domains with no sender authentication.

What the email check tells you

The same facts a mail server would use to decide whether a message lands.

Email check questions

Why does it say “Accepts mail” and not “Deliverable”?

The domain can receive mail, but the individual mailbox was not tested. Some providers refuse to confirm single mailboxes to protect privacy.

What is a catch-all domain?

A domain that accepts mail for any address, real or not. Mail will not bounce, so the specific inbox cannot be confirmed.

Do you send an email to test it?

No. Nothing arrives in the inbox and the owner is not notified.
