How this service works
Validates email syntax, disposable/burner provider status, role accounts, and live DNS MX/SPF/DMARC records. (Live x402 v2, IETF MPP & MCP endpoint at https://company-enrich.agentdiet.dev/v1/spf-dmarc-auditor)
Output
Returns a structured object indicating email syntax validity, whether the domain is a known disposable/burner provider, whether the address appears to be a role account (e.g. info@, admin@), and live DNS lookup results for MX, SPF, and DMARC records on the email's domain.
Example use cases
Screen leads before CRM import
“Before I import this list of leads, can you verify that sarah.jones@startupxyz.com is a legitimate, deliverable email — not a burner or role address — and that the domain has proper MX, SPF, and DMARC records set up?”
Catch fake signups at registration
“A user just signed up with dev@mailinator.com — can you check if that's a disposable or burner email and whether the domain even has real MX records before I let them into the app?”
Audit domain email security posture
“I'm about to send a cold outreach email to ceo@bigclient.com — can you confirm the domain has working MX records and that their SPF and DMARC are configured, so I know my emails won't bounce or get flagged?”
Technical details
Endpoint
GEThttps://company-enrich.agentdiet.dev/v1/spf-dmarc-auditor?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call, comprehensive email health check combining syntax validation, disposable/burner detection, role account flagging, and live DNS MX/SPF/DMARC lookup — especially useful for lead qualification, signup gating, or pre-outreach deliverability audits where you need more than just syntax checking.
Side effects
- Invalid or missing email parameter returns an error
- DNS lookup timeout if the domain's nameservers are slow or unresponsive
- Newly registered domains may lack MX/SPF/DMARC records even if legitimate
- Disposable provider database may not cover all burner services
- Role account heuristics may produce false positives for legitimate personal addresses
