How this service works
Is the domain's email hosted by zendesk mail? Looks up the MX records (Cloudflare DoH) and matches them against zendesk-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 Zendesk Mail, along with the full list of MX host records retrieved via Cloudflare DoH and which specific MX hosts matched Zendesk Mail's known mail-exchanger patterns.
Example use cases
Sales prospecting email stack detection
“I'm about to reach out to techcorp.io — can you check if they use Zendesk Mail for their email hosting? I want to know before I pitch them our support tooling.”
Pre-migration email provider audit
“We're planning to migrate clients off Zendesk Mail next quarter. Can you check whether globalsuppliers.com currently has their email hosted by Zendesk Mail so we can add them to the migration list?”
Competitor intelligence on support tooling
“I'm researching whether startupxyz.com uses Zendesk for their support email — can you look up their MX records and tell me if Zendesk Mail is their email host?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/hosted-by/zendesk-mail?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to definitively determine whether a specific domain's inbound email is handled by Zendesk Mail, particularly for sales prospecting (qualifying Zendesk customers), deliverability audits, or pre-migration planning. Prefer this over generic MX lookup tools when you want Zendesk Mail-specific pattern matching rather than raw DNS data.
Side effects
- Domain does not exist or has no MX records — returns no match with empty MX list
- Cloudflare DoH temporarily unavailable — may return a DNS lookup error
- Domain input missing or malformed — returns a validation or bad request error
- Zendesk Mail changes its MX patterns — results may be stale until pattern list is updated
