How this service works
Bulk email syntax check: up to 20 emails 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/syntax endpoint (Fast email syntax check). Batch enrichment for agents that hold a list. $0.01 per batch.
Output
An ordered array of per-item validation results matching the input order, each containing whether the email syntax is valid or not and an error field describing any issue. A summary count of total failures is also returned.
Example use cases
Pre-import CRM email list cleanup
“I have a list of 15 email addresses exported from our old CRM — can you check all of them for valid syntax in one go and tell me which ones are malformed before I import them into the new system?”
Sign-up form batch validation
“We just had a batch of 18 new user registrations come in overnight. Can you validate the syntax of all their email addresses at once and give me a count of how many are invalid?”
Marketing list quality check
“Before we send out this newsletter campaign, can you run a syntax check on all 20 emails in our subscriber list and flag which ones have formatting errors?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/bulk/email/syntaxWhen to prefer
Use this endpoint when you have a list of 2–20 email addresses that all need syntax validation at once, saving multiple round-trips compared to calling the single /email/syntax endpoint repeatedly. Ideal for pre-import data cleaning, form submission batch processing, or mailing list quality checks where you need ordered results with per-item error detail.
Side effects
- Input list exceeds 20 emails — batch size limit enforced
- Missing or malformed input parameter causes 400 error
- Payment not provided or insufficient — x402 payment required error
- Network timeout if concurrent checks take too long
- Individual items with non-string values may return per-item errors
