How this service works
Bulk is email hosted by rackspace email: 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 domains, each indicating whether that domain's email is hosted by Rackspace Email, along with a per-item error field for any failures and an overall failure count for the batch.
Example use cases
CRM email provider enrichment
“I have a CSV of 20 prospect company domains and I need to know which ones are running Rackspace Email so I can tailor our outreach — can you batch-check them all?”
Competitor infrastructure audit
“Here are 15 domains we're researching: can you tell me which of them host their email through Rackspace Email in one go?”
Lead scoring by email platform
“We're scoring leads by email infrastructure — can you check these 20 domains and flag the ones that are hosted on Rackspace Email so we can route them to the right sales team?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/bulk/email/hosted-by/rackspace-email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to check Rackspace Email hosting status for multiple domains (up to 20) in a single API call rather than making individual requests. It is more efficient and cost-effective for batch enrichment workflows where you already hold a list of domains and need concurrent processing with ordered results.
Side effects
- Exceeding 20 domains per call returns an error or partial results
- Malformed or non-existent domain names produce per-item errors without failing the whole batch
- Network timeouts for individual domain DNS lookups captured in per-item error field
- Missing or empty input list causes request-level validation failure
- Domains with ambiguous or mixed MX configurations may yield inconclusive results
