How this service works
SPF policy lookup for Email operations: Return and parse the domain SPF TXT policy. DNS data only; does not send email or verify that an inbox exists.
Output
Returns the raw SPF TXT DNS record for the domain along with a parsed breakdown of its policy directives, including authorized IP ranges, included domains, and the catch-all qualifier (e.g. ~all, -all). No email is sent and no inbox is verified; this is DNS data only.
Example use cases
Email deliverability audit for domain
“We're having trouble with our emails landing in spam — can you look up the SPF record for acmecorp.com and tell me what it says about authorized senders?”
Security check on suspicious sender domain
“I got an email claiming to be from payroll@bigbank.com — can you fetch the SPF policy for bigbank.com so I can see if their SPF record would allow that kind of spoofing?”
Onboarding domain email configuration review
“We're onboarding a new partner and want to verify their email setup — can you retrieve and parse the SPF TXT record for partnerbrand.io?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-domain-spf-policy-email-operations?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically retrieve and parse the SPF DNS policy for a domain, especially for email security audits, deliverability troubleshooting, or onboarding checks. It is DNS-only and does not send email or verify inboxes, making it safe and read-only. Prefer this over DMARC or DKIM endpoints when specifically diagnosing SPF authorization issues.
Side effects
- Domain has no SPF TXT record — returns empty or null result
- Invalid or non-existent domain name — DNS resolution failure
- SPF record is malformed or exceeds DNS lookup limit — parse error
- Network or DNS timeout — service unavailable error
- Domain uses multiple TXT records causing ambiguity — may return first or flag conflict
