How this service works
Change watch for is email hosted by mailgun: 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 whether the domain's email is currently hosted by Mailgun (true/false), a 'changed' boolean indicating whether the answer differs from the previous check (stored up to 90 days), the specific fields that changed with before/after values, and the timestamp of when it was last seen.
Example use cases
Competitor email infrastructure tracking
“Watch acmecorp.com and tell me if they've switched to Mailgun for their email hosting — I want to know if anything changed since the last check.”
Sales lead email provider detection
“I'm prospecting leads that use Mailgun — check if prospectdomain.io is now hosted by Mailgun and whether that's changed recently.”
Customer migration alert
“Monitor customerdomain.com for me and flag immediately if they start or stop using Mailgun for their email, compared to the last time this was checked.”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/watch/email/hosted-by/mailgun?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to be alerted to changes in whether a domain uses Mailgun for email hosting, rather than just a one-time lookup. It is ideal for scheduled polling workflows where detecting the transition (on or off Mailgun) matters more than the current state alone. Prefer this over the base check endpoint when you want delta information (what changed, when) rather than just the current answer.
Side effects
- Domain not resolvable — MX lookup fails with DNS error
- No previous check stored — first call returns no comparison data, only current result
- Domain input missing or malformed — request rejected
- Cloudflare DoH unavailable — MX lookup cannot be performed
- 90-day history expired — previous result not available for comparison
