How this service works
Change watch for is email hosted by forwardemail: 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 boolean result of whether the domain's email is hosted by Forward Email, a 'changed' true/false flag indicating whether this differs from the last check, an array of changed fields with before/after values, and a timestamp of when the status was last seen. Results from previous calls are retained for 90 days for comparison.
Example use cases
Competitor email stack monitoring
“Watch acmecorp.com and alert me if they switch away from Forward Email — I want to know the moment their email hosting changes.”
Acquisition due diligence tracking
“I'm tracking a list of target companies — start monitoring targetstartup.io and tell me if its email is hosted by Forward Email or if that changes.”
Customer migration detection
“We onboard customers onto Forward Email — can you watch newclient.com and confirm the moment their email hosting shows up as Forward Email so I know the migration worked?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/watch/email/hosted-by/forwardemail?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need ongoing change detection for Forward Email hosting rather than a one-time point-in-time check. Ideal for scheduled monitoring pipelines where you want to be notified only when something changes, avoiding alert fatigue from repeated identical results. Prefer this over the non-watch variant when setting up automated workflows that poll periodically and need delta reporting.
Side effects
- Domain not found or unresolvable — returns an error or null result
- No previous check stored (first call) — 'changed' may be null or false by default
- DNS lookup failure via Cloudflare DoH — may return an indeterminate result
- Payment not processed — request rejected before check is run
- 90-day comparison window expired — previous result discarded, no change comparison available
