How this service works
Bulk catch all hint: up to 20 domains in one call, processed concurrently, results returned in input order with a per-item error field and a count of failures. Same answer per item as the single /email/catch-all-hint endpoint (Catch-all mailbox hint). Batch enrichment for agents that hold a list. $0.01 per batch.
Output
An ordered array of per-domain results matching the input order, each containing the catch-all hint status (same answer as the single /email/catch-all-hint endpoint), a per-item error field if the lookup failed, and a top-level count of total failures across the batch.
Example use cases
Lead list email deliverability enrichment
“I have a list of 15 company domains from my CRM — salesforce.com, hubspot.com, zendesk.com, and 12 more — can you check which of them have catch-all email setups so my sales team knows which contacts might have fake or risky addresses?”
Cold outreach risk screening
“Before we send our campaign, check these 20 domains for catch-all mailbox status: mailchimp.com, constantcontact.com, sendgrid.com, and 17 others — flag any that accept all email so we can mark them as uncertain in our bounce risk report.”
Email verification pipeline batch step
“As part of cleaning our subscriber list, run a catch-all hint check on all 20 domains I'm sending you — I need to know which ones accept every address so we can deprioritize those contacts in our verification workflow.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/bulk/email/catch-all-hintWhen to prefer
Use this endpoint when you have a list of 2–20 domains and need catch-all mailbox hints for all of them efficiently in a single paid call rather than making multiple sequential single-domain requests. It is the right choice for lead enrichment pipelines, cold outreach pre-screening, and email verification workflows where batch throughput matters and you want results in the same order as your input.
Side effects
- Invalid or malformed domain names return per-item errors without failing the whole batch
- Exceeding 20 domains per call results in a request error
- Network timeouts on individual domains contribute to the failure count
- Domains with no MX records may return indeterminate catch-all status
- Rate limiting or payment failure blocks the entire batch call
