Check a domain

Mailrecord reads the published DNS records for a domain — MX, SPF, DMARC, and the DKIM selectors you specify — and states what they declare.

DKIM selectors

DKIM selectors are not discoverable from DNS. Specify the selectors you want to check. Only the selectors provided here will be checked — absence of a lookup is not absence of a key.

What this tool does not do

  • It does not test mail delivery. A valid DNS record does not guarantee mail is delivered.
  • It does not store domains, track users, or share results. No database, no account, no logging.
  • It does not scan subdomains or enumerate targets. Only the domain you type is checked.
  • It does not offer email alerts, scheduled re-checks, or DMARC report ingestion.
