How this service works
Is the domain's email hosted by ionos mail? Looks up the MX records (Cloudflare DoH) and matches them against ionos-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 flag indicating whether the domain's email is hosted by IONOS Mail, the list of MX hosts found via Cloudflare DoH, and which of those MX hosts matched IONOS mail-exchanger patterns.
Example use cases
Sales prospecting email provider detection
“Before I call this lead, can you check if techstartup.de is using IONOS Mail for their email hosting? I want to know their current provider.”
Pre-migration provider verification
“We're onboarding a new client at clientbrand.com — can you confirm whether their email is currently hosted by IONOS Mail so we know what migration steps to plan?”
Deliverability audit for domain
“I'm troubleshooting email deliverability for orders@shopexample.com — can you look up whether shopexample.com is hosted on IONOS Mail and show me their MX records?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/hosted-by/ionos-mail?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically detect whether a specific domain's email is hosted by IONOS Mail, especially for sales intelligence, deliverability analysis, or pre-migration audits. It is purpose-built for IONOS detection using live MX lookups via Cloudflare DoH, making it more reliable than static provider lists. Choose this over generic MX lookup tools when you specifically need IONOS provider matching logic already applied.
Side effects
- Domain does not exist or has no MX records — returns no match with empty MX list
- DNS lookup timeout via Cloudflare DoH — returns error or no result
- Invalid domain format provided — may return error or empty result
- IONOS MX pattern not recognized if IONOS updates their infrastructure
