How this service works
Is the domain's email hosted by mailgun? Looks up the MX records (Cloudflare DoH) and matches them against mailgun'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 Mailgun, along with the full list of MX hosts discovered and which specific MX hosts matched Mailgun's known mail-exchanger patterns.
Example use cases
Sales prospecting for Mailgun migration
“I'm targeting companies that are already using Mailgun for their email — can you check whether acme.com is hosted by Mailgun so I know if they're a fit for our migration service?”
Deliverability audit for outbound campaigns
“Before I set up our email outreach to vendors at techcorp.io, can you tell me if their email is hosted by Mailgun? I need to know their provider for deliverability planning.”
Competitor email infrastructure research
“I want to know which email provider our competitor uses — can you check if mailchimp.com's MX records match Mailgun's patterns and tell me what hosts come back?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/hosted-by/mailgun?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, single-domain check specifically for Mailgun hosting detection using live MX record lookups via Cloudflare DoH. Prefer this over generic MX lookup tools when you need structured yes/no provider detection with matched pattern detail, and over bulk variants when checking a single domain at $0.01 per call.
Side effects
- Domain has no MX records — returns no match with empty MX host list
- Cloudflare DoH lookup failure — DNS resolution error returned
- Invalid or malformed domain input — request rejected
- Domain uses a custom or obfuscated MX configuration that doesn't match known Mailgun patterns — false negative possible
- Rate limiting or payment failure — 402 payment required
