How this service works
Bulk is email hosted by proofpoint: up to 20 domains in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.
Output
An ordered array of per-item results matching the input domain list, each indicating whether the domain's email is hosted by Proofpoint (true/false), plus an error field for any item that failed to resolve. A summary failure count is also returned for the batch.
Example use cases
Sales prospect email security screening
“I have a list of 18 target accounts I'm reaching out to — can you check all of them at once and tell me which ones are running Proofpoint for email, so I know whose inboxes have that filtering layer?”
Cybersecurity vendor research
“We're compiling a report on enterprise email security adoption — can you batch-check these 20 company domains and flag which ones are hosted by Proofpoint?”
Email deliverability pre-flight check
“Before we send our outreach campaign, check all the domains in this list and tell me which ones use Proofpoint email hosting, along with any that failed to resolve.”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/bulk/email/hosted-by/proofpoint?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have a list of 2–20 domains and need to check Proofpoint email hosting for all of them in a single call rather than making individual requests. It is more cost-efficient and faster than sequential single-domain lookups, and it preserves input order for easy mapping back to your original list.
Side effects
- Invalid or malformed domain in input causes per-item error with failure count incremented
- Batch exceeds 20 domain limit resulting in request rejection
- DNS lookup timeout for a domain produces an error entry for that item
- Network or upstream DNS failure causes multiple item errors
- Empty input list returns an empty result array
