How this service works
DMARC enforcement check for Vendor screening: Classify the published DMARC policy as monitor, quarantine, reject, or missing. DNS data only; does not send email or verify that an inbox exists.
Output
Returns the DMARC enforcement classification for the queried domain: one of 'reject', 'quarantine', 'monitor' (p=none), or 'missing' (no DMARC record found). Derived entirely from DNS TXT record data; does not send email or probe mailboxes.
Example use cases
Vendor onboarding email security check
“Before we add TechSupplierCo to our approved vendor list, can you check what DMARC policy techsupplierco.com is publishing? I need to know if they're at reject, quarantine, monitor, or missing.”
Phishing risk triage for supplier list
“I have a domain sendgrid.net — can you look up its DMARC enforcement level so I can assess whether unauthenticated email from them poses a phishing risk?”
Compliance audit for partner domains
“We're auditing our partners' email security. Can you check the DMARC policy published by partnerbrand.com and tell me if it's enforced at the reject level or something weaker?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-domain-dmarc-enforcement-check-vendor-screening?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, DNS-only classification of a domain's DMARC enforcement stance for vendor screening, supplier risk scoring, or compliance audits. It is ideal when you need a fast, cheap policy signal without sending email or verifying inbox existence. Prefer this over full email deliverability checks when the goal is specifically to assess whether a domain owner has signaled email authentication enforcement via DMARC.
Side effects
- Domain does not exist in DNS — returns missing or error
- Malformed domain input — validation error
- DNS lookup timeout — transient failure, retry recommended
- DMARC record exists but is unparseable — may return ambiguous classification
- Rate limiting or network issues on the DNS resolver side
