How this service works
Is the domain's email hosted by intercom mail? Looks up the MX records (Cloudflare DoH) and matches them against intercom-mail'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 Intercom Mail, along with the full list of MX hosts discovered via Cloudflare DoH and which specific hosts matched Intercom's mail-exchanger patterns.
Example use cases
Pre-sales email provider research
“Before I reach out to this prospect at hubspot.com, can you tell me if they use Intercom Mail for their email hosting? I want to know their email infrastructure setup.”
Migration compatibility check
“We're planning to migrate customers off Intercom Mail — can you check if stripe.com is currently hosted by Intercom Mail so we know if they'd be affected?”
Deliverability provider audit
“I'm auditing email deliverability for a list of domains — start with notion.so and tell me if their email is hosted by Intercom Mail, including which MX hosts matched.”

It is purpose-built for Intercom Mail detection using live MX record lookups rather than cached or static data.

- Cloudflare DoH lookup failure returns an error
- Domain has MX records but none match Intercom Mail patterns, returning 'no'
- Missing or malformed query parameter causes request failure
- Rate limiting or payment failure prevents lookup
