How this service works
Bulk is email hosted by runbox: 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 results matching the input domain list, where each item contains a boolean indicating whether the domain's email is hosted by Runbox, an optional per-item error field if the check failed, and a top-level failure count summarizing how many items could not be resolved.
Example use cases
CRM email provider enrichment
“I have a list of 18 prospect domains from our CRM — can you batch-check all of them right now and flag which ones are using Runbox to host their email?”
Competitor infrastructure audit
“We're researching which of our competitors use Runbox for email. Here are 20 company domains — run them all through at once and tell me which ones are Runbox-hosted, plus note any that errored out.”
Privacy-focused user identification
“I want to know which of these 12 newsletter subscriber domains rely on Runbox for email hosting — check them all in one go and give me the results in the same order I listed them.”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/bulk/email/hosted-by/runbox?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to check more than one domain for Runbox email hosting in a single operation. It processes up to 20 domains concurrently and returns results in input order, making it far more efficient than calling the single-domain endpoint repeatedly. Prefer it for batch enrichment pipelines, CRM data augmentation, or any workflow where you hold a list of domains and need to screen them all at once. Use the single endpoint only if you have exactly one domain to check.
Side effects
- Input list exceeds 20 domains — request rejected or truncated
- Individual domain DNS lookup fails — per-item error field populated, failure count incremented
- Malformed domain string in input — per-item error returned
- Network timeout for concurrent lookups — partial results with failures noted
- Empty input list — returns empty results array
