Email Validations

Create a batch email validation job

Creates an asynchronous batch validation job for up to 1,000 email addresses.

post/email_validations/batch

Headers

Idempotency-Keystring

Optional opaque, unquoted key for safely retrying the same logical request. Keys must contain 1 to 255 letters, numbers, hyphens, or underscores. Generate a unique UUID v4 for each operation and reuse it only when retrying that operation with the same request. Invalid headers—including duplicate, empty, malformed, or overlong values—return 400 with error code 10015. A request already in progress with the same key returns 409; reusing the key with a different request returns 422. Only successful responses are replayed, for up to 24 hours. Do not include sensitive data in the key.

Request body

emailsstring[] required
webhook_urlstring uri

URL for batch completion webhook. Empty string is treated as omitted. SSRF-protected; private/reserved IPs and internal hostnames are rejected.

Response

Batch validation job accepted. Poll GET /email_validations/batch/{id} with the returned batch id to retrieve results.
