Validate multiple email addresses
Paste up to 20 addresses in one request
Place each address on its own line or separate addresses clearly. The batch validator processes up to 20 addresses per request.
When more than 20 addresses are supplied, only the first 20 are processed. Split larger lists into additional requests.

You can perform up to 10 single-email validations and 2 batch validations every 24 hours. Each batch can contain a maximum of 20 email addresses, allowing you to validate up to 40 addresses in batches per 24-hour period.
