Example prompt: Can you check if the domain acme.com has its email hosted by HubSpot Mail — I want to know if their MX records match HubSpot's mail exchangers?

## When to prefer this

Use this endpoint when you need to quickly determine whether a specific domain is using HubSpot Mail as its email hosting provider, based on authoritative DNS MX record data. It is ideal for sales intelligence workflows, pre-migration audits, email deliverability diagnosis, and CRM enrichment where HubSpot Mail specifically (not other providers) is the target of detection. Choose this over generic MX lookup tools when you want structured yes/no output with matched pattern details specifically for HubSpot Mail.

## Known failure modes

- Domain does not exist — DNS lookup fails, no MX records returned
- Domain has no MX records configured — returns no match
- Cloudflare DoH temporary unavailability — lookup may time out or return error
- Invalid or malformed domain input — request rejected
- Payment failure — call blocked if USDC payment not processed

## How this service works

Is the domain's email hosted by hubspot mail? Looks up the MX records (Cloudflare DoH) and matches them against hubspot-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 HubSpot Mail, along with the full list of MX hosts discovered from DNS and which specific MX records matched HubSpot Mail's known mail-exchanger patterns.
