How this service works
Bulk is email hosted by mailbox org: 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-domain results (matching input order), each containing a boolean indicating whether that domain's email is hosted by Mailbox.org, a per-item error field if the check failed, and an overall failure count for the batch.
Example use cases
Sales prospect email stack research
“I have a list of 18 prospect company domains. Can you check all of them at once and tell me which ones are running their email through Mailbox.org? I want to know so I can tailor my outreach approach.”
Privacy-focused hosting audit
“We're auditing our partner ecosystem — here are 20 domains. Check which of them host their email on Mailbox.org so we can flag the privacy-focused operators in our CRM.”
Competitive intelligence on email providers
“I'm doing market research on email hosting trends. Can you batch-check these 20 domains and return a list of which ones use Mailbox.org, along with any that errored out?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/bulk/email/hosted-by/mailbox-org?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have a list of 2–20 domains and need to check Mailbox.org hosting status for all of them in a single paid call rather than making multiple single-domain requests. It is more cost-efficient and faster than looping the single endpoint, and it returns results in input order with structured per-item error reporting.
Side effects
- Input list exceeds 20 domains — batch size limit enforced
- Invalid or malformed domain names cause per-item errors with error field populated
- DNS resolution failures for specific domains increment failure count but don't abort the batch
- Network timeout on MX/SPF lookup returns per-item error
- Payment failure (x402) prevents the call from being processed
