Definition
Webhooks allow you to receive real-time email event data without polling the API. Common webhook event types include: delivered (message accepted by receiving server), opened (tracking pixel loaded), clicked (link in email was clicked), bounced (temporary or permanent delivery failure), complained (recipient marked as spam via FBL), unsubscribed (recipient clicked unsubscribe link), and dropped (message rejected before sending attempt). Each event includes metadata like timestamp, recipient email, campaign ID, and event-specific data. Webhooks enable real-time list cleansing, live dashboards, and dynamic content updates.
