How this service works
Is the domain's email hosted by icloud? Looks up the MX records (Cloudflare DoH) and matches them against icloud's mail-exchanger patterns, returning yes/no, the MX hosts and which matched. Provider detection for deliverability, sales and migration work. $0.01 per lookup.
Output
Returns a yes/no answer indicating whether the domain's email is hosted by iCloud, along with the raw MX host records retrieved via Cloudflare DNS-over-HTTPS and the specific MX hostnames that matched iCloud's known mail-exchanger patterns.
Example use cases
Pre-migration iCloud email audit
“I'm migrating clients off iCloud mail to Google Workspace — can you check if techstartup.io is currently hosted by iCloud so I know what I'm dealing with?”
Sales lead email provider detection
“Before I reach out to the team at mydesignstudio.com, can you tell me if their email is on iCloud? I want to know their setup before the pitch.”
Deliverability routing check
“I need to know if newsletters sent to customers at creativecollective.net will hit iCloud mail servers — can you check if that domain uses iCloud for email?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/hosted-by/icloud?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to detect iCloud/Apple Mail hosting for a domain, for example in deliverability pipelines, sales prospecting to understand prospect tech stack, or migration planning from iCloud. Prefer this over generic MX lookup tools when you need a pre-classified yes/no answer against iCloud patterns rather than raw DNS data.
Side effects
- Domain does not exist or has no MX records — returns no match with empty MX list
- DNS resolution failure via Cloudflare DoH — may return an error or inconclusive result
- Domain has MX records but none match iCloud patterns — returns no
- Malformed or missing domain input — likely returns a validation error
- Temporary upstream DNS unavailability — may cause lookup timeout
