Request body: {"email": "{{email_from_trigger}}"}. Header: Authorization: Bearer YOUR_API_KEY. Content-Type: application/json.
The response includes a "classification" field: deliverable, invalid, disposable, catch_all, or unknown. Add a Router/Filter to only continue for deliverable results.
Route deliverable contacts to Mailchimp, Klaviyo, HubSpot, Salesforce, or any ESP in your Zap/scenario. Invalid contacts can be logged to a Google Sheet or Airtable for review.
