Example prompt: Can you check if acmecorp.com uses Mailchimp Mandrill for their email hosting — look up the MX records and tell me if any of them match Mandrill's patterns?

## When to prefer this

Use this endpoint when you need to specifically identify whether a domain uses Mailchimp Mandrill (including transactional Mandrill) as its email provider. Prefer this over generic MX lookup tools when you need provider-level ESP detection with pre-built Mandrill pattern matching, especially for sales intelligence, email migration planning, or deliverability research workflows.

## Known failure modes

- Domain has no MX records — returns no match with empty MX host list
- Invalid or non-existent domain — DNS lookup fails or returns an error
- Cloudflare DoH is unreachable — lookup cannot complete
- Domain uses a Mandrill IP range not yet in the pattern list — false negative
- Payment not included or insufficient — 402 Payment Required response
