How this service works
Is the domain's email hosted by improvmx? Looks up the MX records (Cloudflare DoH) and matches them against improvmx'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 flag indicating whether the domain's email is hosted by ImprovMX, along with the full list of MX hosts found and which specific MX records matched ImprovMX's known mail-exchanger patterns.
Example use cases
Sales lead email provider detection
“Before I reach out to leads at startupxyz.com, can you check whether their email is hosted by ImprovMX? I want to know if they're using email forwarding rather than a real mail server.”
Pre-migration email infrastructure audit
“We're about to migrate email for clientdomain.io — can you check if they're currently on ImprovMX so I know what we're working with before we start?”
Email deliverability provider check
“I need to know if newsletter.example.com is using ImprovMX as their email host — look up their MX records and tell me if any match ImprovMX's patterns.”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/hosted-by/improvmx?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to specifically detect ImprovMX as the email hosting provider for a domain, such as during sales prospecting, email migration audits, or deliverability analysis. It is more precise than generic MX lookup tools because it applies ImprovMX-specific pattern matching rather than returning raw DNS data.
Side effects
- Domain does not exist or has no MX records — returns no match
- Cloudflare DoH lookup failure due to network or upstream DNS errors
- Domain provided without required query parameter — request rejected
- Ambiguous or partial MX records may yield false negatives if ImprovMX pattern list is incomplete
