How this service works
SPF record check for a domain: fetches and parses the SPF record (all qualifier, includes, ip4/ip6, a, mx, redirect), counts DNS-lookup mechanisms against the 10-lookup limit by expanding includes, flags duplicate records and common errors. Email deliverability and anti-spoofing audits. $0.01 per domain.
Output
Returns a parsed breakdown of the domain's SPF record including the all-qualifier setting, list of include mechanisms, ip4/ip6 ranges, a and mx directives, redirect targets, total DNS lookup count versus the 10-lookup limit, flags for duplicate SPF records, and identified common errors or misconfigurations.
Example use cases
Pre-send email deliverability audit
“Before we launch this email campaign, check the SPF record for ourstartup.io — I want to know if we'll hit the 10-lookup limit, whether the -all qualifier is set correctly, and if there are any errors we need to fix.”
Anti-spoofing compliance check
“Our security team needs to verify that acmecorp.com has proper SPF anti-spoofing in place — can you fetch and analyze the SPF record and flag any gaps or misconfigurations?”
Diagnosing email bounce issues
“Emails from clientdomain.com keep bouncing or landing in spam — can you pull their SPF record and tell me exactly what mechanisms it includes, how many DNS lookups it uses, and what might be causing deliverability problems?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/email/spfWhen to prefer
Use this endpoint when you need a detailed, structured audit of a domain's SPF configuration — especially when diagnosing deliverability issues, verifying anti-spoofing posture, or checking DNS lookup depth. Prefer it over generic DNS lookup tools when you need SPF-specific parsing (include expansion, lookup counting, qualifier analysis) in a single call at low cost ($0.01). Pair with the sibling email-deliverability-report endpoint if you also need DMARC/DKIM in the same request.
Side effects
- Domain has no SPF record — returns empty or not-found result
- Domain does not exist or DNS resolution fails — DNS error returned
- SPF record is malformed beyond basic parsing — partial parse with error flags
- Rate limiting or network timeout reaching authoritative DNS — error response
- Invalid domain input format — validation error
