How this service works
Bulk mail provider detect: up to 20 domains in one call, processed concurrently, results returned in input order with a per-item error field and a count of failures. Same answer per item as the single /dns/mail-provider endpoint (Mail provider detection for a domain). Batch enrichment for agents that hold a list. $0.01 per batch.
Output
An ordered array of per-domain results matching the input order, each containing the detected mail provider name (e.g. Google Workspace, Microsoft 365, Zoho Mail, custom), plus a per-item error field if detection failed for that domain, and an overall count of failures across the batch.
Example use cases
Enrich sales prospect list with email stack
“I have a list of 15 prospect company domains from my CRM — acme.com, globex.io, initech.net, and 12 others — can you find out which mail provider each of them uses so I know if they're on Google Workspace, Office 365, or something else?”
Segment leads by email infrastructure
“Before we launch this email campaign, check which mail providers these 20 target domains are using so we can group them by provider type — here's the list: domain1.com, domain2.com, … domain20.com.”
Audit acquired company domains
“We just merged with a company that has 18 domains — can you run a bulk check to find out what mail provider each one is on so our IT team knows what migrations are needed?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/bulk/dns/mail-providerWhen to prefer
Choose this endpoint when you have a list of 2–20 domains and need mail provider information for all of them — it processes concurrently and returns results in input order, making it far more efficient than calling the single-domain endpoint repeatedly. Prefer it for batch enrichment workflows, CRM enrichment, sales prospecting, or IT audits where multiple domains must be checked in one shot.
Side effects
- Domain not found or does not exist — per-item error field populated
- DNS lookup timeout for a specific domain — item marked with error, others succeed
- Invalid domain format in input — per-item validation error
- Batch exceeds 20-domain limit — request rejected
- Payment not completed (x402) — entire call rejected before processing
