How this service works
Change watch for spf authorizes postmark: runs the check, compares it with the result from your previous call for the same domain (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.
Output
Returns the current SPF-authorizes-Postmark answer (true/false), a changed flag indicating if it differs from the previous call for the same domain, a list of fields that changed with their before and after values, and the timestamp of when the prior state was last seen. Results are compared against stored state retained for 90 days.
Example use cases
Postmark delivery break alert
“Monitor acmecorp.com and alert me immediately if their SPF record stops authorizing Postmark to send email — I need to know the moment that changes.”
Onboarding SPF verification check
“We just configured Postmark for newclient.io — can you check whether their SPF record now authorizes Postmark and tell me if that's different from what you saw before?”
Multi-tenant email config drift detection
“Schedule a daily check on partnerbrand.net to see if Postmark is still authorized in their SPF record, and show me what changed if anything is different from yesterday.”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/watch/email/spf-authorizes/postmark?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to continuously monitor whether Postmark remains authorized in a domain's SPF configuration and be alerted to changes, rather than just performing a one-off check. It is especially suited for scheduled polling workflows, automated alerting pipelines, or multi-tenant SaaS platforms tracking email configuration health across many customer domains. Prefer this over a plain SPF check endpoint when change detection and historical diffing (before/after) are required.
Side effects
- Domain not provided or invalid — likely returns an error or empty result
- No previous result stored (first call for this domain) — changed flag may be false or undefined with no before values
- DNS lookup failure for the domain's SPF record — may return an error or indeterminate status
- Domain has no SPF record — returns not-authorized with no change data if first call
- Stored result older than 90 days has expired — treated as first call with no prior comparison
