Example use cases
Vendor email security audit
“I need to verify that our top 5 suppliers have proper email security in place — can you check SPF, DKIM, and DMARC for acme.com, globalsupply.com, partnerco.com, vendorx.com, and logisticsllc.com?”
Pre-campaign domain validation
“Before I start our email marketing campaign, can you check whether our sending domain newsletter.mycompany.com has SPF and DMARC properly set up so we don't end up in spam?”
Phishing investigation triage
“I got a suspicious email claiming to be from payments.bigbank.com — can you pull the email security and DNS records for that domain so I can tell if it's a spoofed or legitimate sender?”
Technical details
Endpoint
GEThttps://domaindna-api.cybermaxtools.com/x402/api/email-security?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call solution for email security posture across SPF, DKIM, and DMARC alongside domain age, with DNS evidence included. It is especially useful for security audits, phishing investigation, vendor risk assessment, and email deliverability checks. Prefer it over manual DNS lookups or separate tools when you need consolidated, structured output with supporting evidence in one request.
Side effects
- Domain does not exist or is unresolvable — returns empty or error response
- Domain has no SPF, DKIM, or DMARC records configured — fields returned as null or absent
- Invalid input format (not a valid domain, URL, or email) — returns validation error
- More than 5 domains submitted in a single call — request rejected
- Network timeout reaching the target domain's DNS — partial results returned
- Payment not completed — 402 response requiring x402 micropayment
