How this service works
Email authentication posture for a domain - SPF with lookup count, DMARC policy and reporting, DKIM selectors, MX, MTA-STS, TLS-RPT and BIMI with prioritised issues
Output
A JSON object containing: domain verdict and notes; SPF record text with parsed mechanisms, all-qualifier policy, included domains, and DNS lookup term count; DMARC policy with aggregate/forensic report addresses, policy level (none/quarantine/reject), percentage applied, and SPF/DKIM alignment modes; DKIM selectors found; MX records with hostnames and priority values; MTA-STS and TLS-RPT configuration; BIMI presence flag; and a prioritised list of issues to remediate.
Example use cases
Pre-send deliverability audit
“Before we start our email campaign, can you audit the email authentication setup for ourbrand.com and tell me if there are any SPF, DMARC, or DKIM issues we need to fix?”
Security posture review for acquired domain
“We just acquired newcompany.com — can you pull a full email authentication report including DMARC policy, SPF record, MX hosts, and whether BIMI is set up, so we know what needs hardening?”
Diagnosing deliverability failures
“Emails from clientdomain.com keep landing in spam — can you check their email authentication posture, including SPF lookup count and DMARC reject/quarantine settings, and list the prioritised issues?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/email/auth?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call, comprehensive email authentication audit covering SPF, DMARC, DKIM, MX, MTA-STS, TLS-RPT, and BIMI together with prioritised remediation issues. Prefer it over generic DNS lookup tools when you want pre-parsed, structured email security posture data with actionable issue rankings rather than raw DNS responses.
Side effects
- Domain does not exist or is unresolvable — returns null or empty results for DNS records
- Domain has no SPF or DMARC record published — fields returned as null with appropriate notes
- DNS lookup timeout or transient failure — may return partial results
- Invalid domain format provided — likely returns error or empty response
- DNS lookup limit exceeded for SPF — flagged in dns_lookup_terms field
