How this service works
Check a domain's email authentication: SPF and DMARC TXT records with presence flags and policy. Use before sending email or vetting a sender domain.
Output
Returns whether SPF and DMARC TXT DNS records exist for the queried domain (boolean presence flags), the raw record content, and the parsed DMARC policy (e.g. none, quarantine, reject) if a DMARC record is found.
Example use cases
Vet a vendor's email domain
“Before we start accepting invoices from payments@acmecorp.com, can you check if acmecorp.com has proper SPF and DMARC records configured and what policy they enforce?”
Pre-send deliverability check
“I'm about to send a bulk email campaign from our domain newsletter.mycompany.com — can you verify it has SPF and DMARC set up so our emails won't be flagged as spam?”
Phishing domain investigation
“I got a suspicious email claiming to be from support@secure-paypal-verify.com — can you check if that domain has any SPF or DMARC records, so I know if it's a legitimate sender?”
Technical details
Endpoint
GEThttps://164.160.90.241.sslip.io/api/sec-email-deliverability-spf-dmarc?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, programmatic check of both SPF and DMARC records for any public domain in a single call — ideal for pre-send deliverability validation, sender vetting workflows, or security investigation pipelines where a combined email-auth status is needed without querying DNS resolvers directly.
Side effects
- Domain does not exist — DNS lookup fails with NXDOMAIN
- Domain has no SPF or DMARC records — presence flags returned as false with empty record fields
- Malformed domain input — request returns a validation error
- DNS resolver timeout — transient network error may cause lookup failure
- Private or non-public domain — resolution may not return results
