How this service works
Is the domain's email hosted by proofpoint? Looks up the MX records (Cloudflare DoH) and matches them against proofpoint'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 Proofpoint, along with the full list of MX hosts discovered and which specific MX records matched Proofpoint's known mail-exchanger patterns.
Example use cases
Sales prospecting email stack detection
“Before I reach out to databricks.com, can you check if they're using Proofpoint for their email? I want to know if my outreach might be filtered by Proofpoint's security.”
Email migration pre-flight check
“We're planning to migrate example-corp.com off Proofpoint — can you confirm that domain is currently hosted by Proofpoint by checking its MX records?”
Security vendor competitive intelligence
“I'm building a list of enterprise clients using Proofpoint — can you check whether techfirm.io and globalco.com have Proofpoint hosting their email?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/hosted-by/proofpoint?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to definitively determine if a specific domain routes its email through Proofpoint, particularly for sales prospecting, deliverability planning, or pre-migration audits. It is more reliable than generic MX lookup tools because it applies Proofpoint-specific pattern matching rather than raw record inspection. Prefer this over manual DNS lookups or broad email provider detection APIs when Proofpoint specifically is the provider you need to confirm.
Side effects
- Domain does not exist or has no MX records — returns no match
- Cloudflare DoH lookup timeout or DNS resolution failure
- Domain uses a custom MX hostname that aliases Proofpoint but doesn't match known patterns — false negative
- Invalid or malformed domain input — error response
- Proofpoint infrastructure changes causing pattern mismatch — stale detection
