How this service works
Bulk is email hosted by improvmx: 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 input order), each containing a boolean indicating whether the domain's email is hosted by ImprovMX, plus a per-item error field for any lookup failures, and an overall failure count for the batch.
Example use cases
Sales lead email provider screening
“I have a list of 15 prospect domains from our CRM — can you check all of them at once to see which ones are using ImprovMX for their email hosting? Here they are: acme.io, brightco.com, swiftdeal.net, ... I want the results in the same order with any failures noted.”
Fraud detection domain audit
“Flag any domains in this batch that rely on ImprovMX for email, since we consider that a risk signal for throwaway business identities — please check all 20 at once: domain1.com through domain20.com.”
Email infrastructure migration audit
“Before we migrate, I need to know which of these 12 client domains are currently on ImprovMX for email hosting — run them all through at once and tell me the outcome per domain with any lookup errors.”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/bulk/email/hosted-by/improvmx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to classify multiple domains (up to 20) for ImprovMX email hosting in a single call rather than making repeated single-domain requests. Prefer it over the single endpoint when processing lists of domains for batch enrichment workflows, lead scoring pipelines, or fraud screening. It's cost-effective at $0.10 per batch of up to 20 and returns results in input order, making it easy to zip back against your original list.
Side effects
- DNS resolution failure for one or more domains returns per-item error rather than crashing the batch
- More than 20 domains submitted causes rejection or truncation
- Invalid domain format in input produces per-item error field
- Network timeout on MX lookup returns error for affected item but other items still resolve
- Payment failure (x402) prevents the call from executing entirely
