How this service works
Email security check for a domain: SPF record present and its content, DMARC record and policy (none / quarantine / reject), MX records and mail provider. Tells you whether a domain is protected against spoofing and phishing. Email authentication audit, vendor vetting, deliverability troubleshooting. $0.01 per domain.
Output
Returns the domain's SPF record and its full content, DMARC record and enforcement policy level (none, quarantine, or reject), MX records and identified mail provider — together providing a clear verdict on whether the domain is protected against email spoofing and phishing.
Example use cases
Vendor email security vetting
“Before we onboard this new supplier, can you check if their domain vendor-example.com has SPF and DMARC configured and what their DMARC policy is — I need to know if they're protected against spoofing.”
Pre-send deliverability audit
“I'm about to launch an email campaign from our domain mycompany.com — can you verify our SPF and DMARC records are correctly set up and tell me what policy we're running?”
Phishing risk check on unknown sender
“I got an email claiming to be from bigbank-support.com and I'm not sure if it's legit — can you check if that domain has real SPF and DMARC protection or if it's likely spoofed?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/email-securityWhen to prefer
Choose this endpoint when you need a quick, consolidated email security audit for a single domain covering SPF, DMARC policy level, and MX/mail provider in one call — especially useful for vendor vetting, phishing risk assessment, or deliverability troubleshooting. Prefer this over a generic DNS lookup when you specifically want email authentication analysis with human-readable security verdicts rather than raw DNS records.
Side effects
- Domain does not exist or has no DNS records — returns empty or error for all fields
- Domain has SPF but no DMARC record — partial result with DMARC absent
- Malformed domain input — may return error or empty response
- Network timeout when querying DNS — may result in incomplete data
- Payment of $0.01 USDC not provided — request rejected with 402 status
