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.
Example use cases
Sales prospecting email platform detection
“I'm researching leads before a sales call — can you tell me if techcorp.io uses HubSpot Mail for their email hosting? I want to know before I pitch our HubSpot integration.”
Pre-migration email infrastructure audit
“We're planning to migrate our client startupxyz.com to HubSpot Mail — can you check whether their domain's MX records already point to HubSpot so I know what we're starting with?”
Deliverability diagnosis for HubSpot routing
“We're seeing email deliverability issues between our platform and newsletter.co — can you check if newsletter.co is hosted on HubSpot Mail by looking up their MX records?”

Endpoint
GEThttps://email.intel.rallylive.ca/email/hosted-by/hubspot-mail?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
