validation

Validate before you send to protect sender reputation: bounce rate is a top lever on inbox placement, and a dead address caught here never costs you a bounce. Validate before a list's first campaign launch, before re-sending to a list older than ~90 days, and before re-engaging non-responders on lists 6+ months old.

Asynchronous email validation, paid with Data Tokens: submit emails or existing prospects, poll the batch until Completed, and read the outcome from each prospect's validation fields (validationStatus, validatedAt — the same fields the prospect validationStatus filter reads).

The flow is two calls: validation/post_emails queues a batch and returns its batchId; validation/batches_by_id reports progress, aggregate counts, and per-email results. Validation is not instant — expect to poll.
