How this service works
Change watch for dkim selector 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 Postmark DKIM selector value for the domain, a boolean 'changed' flag indicating whether it differs from the previous check (stored up to 90 days), a list of changed fields with before/after values, and a timestamp of when the record was last seen.
Example use cases
Email deliverability change detection
“Watch the Postmark DKIM selector for acmecorp.com and alert me if it changes — I need to know if our email authentication config has been modified unexpectedly.”
Post-migration DKIM verification
“We just moved our email setup — can you check whether the Postmark DKIM selector for mybrand.io has changed compared to what was there 24 hours ago, and show me the before and after values?”
Scheduled DNS audit for SaaS platform
“Set up a recurring check on the Postmark DKIM selector for clientdomain.net so I get a report any time it changes, including which fields changed and what the previous values were.”

Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/dkim/postmark?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect and be alerted to changes in a domain's Postmark DKIM selector over time, particularly for scheduled monitoring or auditing email authentication configuration drift. It is specifically designed for Postmark's DKIM selector (not generic DKIM or other ESPs) and provides diff-aware change detection rather than just a raw DNS lookup.
Side effects
- Domain not found or has no Postmark DKIM selector — returns current answer with no previous comparison data
- No previous check exists within 90-day window — changed flag may be null or false with no diff
- Domain parameter missing or malformed — returns validation error
- DNS lookup failure for the domain — returns error with no result
- Network timeout reaching DNS resolver — returns error
