Validate emails in batch

POST

/email-validation/batch

Submit up to 500 000 emails in a single request. We automatically
remove duplicates (case-insensitive) before processing, so you only pay
for unique addresses.

Cost: 1 credit per unique email, reserved when you submit. Any unused
credits are refunded automatically when you fetch results.

Webhook callbacks

If you include a webhookUrl, your server will receive:

A per-result callback every time an individual email finishes
validation. See emailValidationResult
for the exact payload.

A completion callback once every email in the batch has been
processed. See emailValidationCompletion
for the exact payload.
