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://shopify-intel.agentdiet.dev/v1/spf-dmarc-auditor)
Output
Returns a structured object indicating whether the email passes syntax checks, whether the domain is associated with a disposable or burner provider, whether the account appears to be a role address (e.g. info@, admin@), and the live DNS status of MX, SPF, and DMARC records for the email's domain, enabling a full deliverability and security assessment.
Example use cases
Screening signups for burner emails
“Before I add this user to our mailing list, can you verify that signup@tempmail.org isn't a disposable or burner email address and that the domain actually has MX records set up to receive mail?”
Pre-send deliverability audit
“I'm about to send a campaign to contact@acmecorp.com — can you check that the email address is syntactically valid, the domain has working MX records, and that SPF and DMARC are properly configured so my emails won't bounce or get flagged?”
Blocking role accounts from lead pipeline
“We got a form submission from noreply@bigcompany.com — can you tell me if that's a role-based account and whether it's actually deliverable, or if we should reject it from our CRM pipeline?”
Technical details
Endpoint
GEThttps://shopify-intel.agentdiet.dev/v1/spf-dmarc-auditor?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, live check combining syntax validation, disposable email detection, role account identification, and real-time DNS MX/SPF/DMARC verification in a single call — especially useful for lead qualification, signup screening, or pre-send deliverability audits where both inbox reachability and email security posture matter.
Side effects
- Missing or malformed email parameter returns a validation error
- DNS lookup timeout if the domain's nameservers are slow or unreachable
- Unrecognized disposable providers may not be flagged if not in the blocklist
- Domain exists but has no MX records — reported as non-deliverable
- Payment failure via x402 if USDC balance is insufficient
