Check any domain's email and DNS posture

SPF, DMARC, DKIM, DNSSEC and CAA — the records a security questionnaire asks about. No account, no email address, no charge.

These are public DNS lookups — the same queries any mail server makes before accepting a message. Nothing is sent to the domain's website or applications, no page is loaded, no port is touched, and nothing is stored. Like any lookup, the query itself reaches whoever runs the domain's DNS.
