How this service works
VerifyPulse is a high-speed B2B email verification engine. Validate RFC syntax, resolve live DNS MX records, filter 3,800+ disposable domains, and run simulated SMTP handshakes in sub-140ms. Stop bounces before sending.
Output
Returns a JSON object with the queried domain, a boolean 'compliant' flag indicating overall DMARC compliance, a boolean 'spf_valid' flag, and the DMARC policy string (e.g. 'reject', 'quarantine', 'none').
Example use cases
Pre-send domain compliance screening
“Before we send this outbound sales sequence, check if acme.com has valid SPF and a DMARC policy in place — I want to know if they're compliant before we reach out.”
Vendor email security audit
“I need to audit our top 10 supplier domains for DMARC compliance — start with stripe.com and tell me whether it has SPF set up and what the DMARC policy is.”
Inbound sender trust verification
“Someone claiming to be from microsoft.com just emailed us — can you check if microsoft.com actually has a DMARC reject policy and valid SPF so I know if it's likely legitimate?”
Technical details
Endpoint
GEThttps://verifypulse-seven.vercel.app/v1/x402/compliance-dmarc?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, real-time check of a specific domain's DMARC and SPF compliance status before sending email, auditing senders, or verifying inbound email legitimacy. Prefer this over full email address verification endpoints when only domain-level DNS security posture is needed.
Side effects
- Domain does not exist — DNS lookup fails, may return non-compliant or error response
- Domain has no MX records — SPF/DMARC may be absent, returns spf_valid: false
- Malformed domain input — API may return validation error
- Temporary DNS resolution failure — transient errors possible for live DNS queries
- Domain with no DMARC record — returns compliant: false with dmarc_policy absent or null
