How this service works
Change watch for is email hosted by hey: 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 Hey, a 'changed' true/false flag comparing to the previous check (stored 90 days), the specific fields that changed with before/after values, and the timestamp of when the result was last seen.
Example use cases
Competitor email provider migration alert
“Keep an eye on stripe.com and let me know if they ever switch to Hey for their email hosting — I want to know right away if something changes compared to what was detected before.”
Customer onboarding email stack verification
“Check whether acme.io is currently using Hey for email, and tell me if anything has changed since the last check — including what specifically changed and when it was last seen.”
Portfolio domain email infrastructure monitoring
“Set up a change watch on basecamp.com so I get notified whenever its Hey email hosting status flips — show me the before and after values when it does change.”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/watch/email/hosted-by/hey?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect changes in Hey email hosting over time rather than just a one-time check. It is ideal for scheduled monitoring workflows where you want to be alerted when a domain starts or stops using Hey, with structured before/after change data. Prefer the non-watch version for simple one-off checks, or the bulk endpoint if checking many domains simultaneously.
Side effects
- Domain not provided or invalid — missing required query parameter
- No previous check stored (first-time call) — 'changed' may be null or baseline
- DNS resolution failure — upstream Cloudflare DoH lookup error
- Rate limiting or payment failure — x402 payment not accepted
- Domain has no MX records — result defaults to false with no hosting detected
