We check the public records that help mail systems identify your messages.
DNS data comes from Google Public DNS. No account access is needed.
DMARC

MX
Where does incoming email go?
DKIM
Does your chosen sender publish a signing key?
A DNS check cannot prove inbox placement or confirm that a real message passes DKIM and DMARC alignment. Send a test email and inspect its headers after fixing records.
