Easily create email webhooks
Set up webhooks in minutes via API or the app to start receiving information about transactional events. Simply configure your endpoint URL and choose the events you want to track.
Receive instant push updates
Use webhooks to listen for email events without wasting time constantly polling the API. As soon as updates are pushed to the server, the JSON payload will be posted on the callback URL.
Send secure HTTP requests
Protect your webhook URLs from malicious activity and false events with secure signature headers. Every HTTP POST request sent to your receiving app contains a secret signature key that is unique to you.
Monitor events as they happen
Create your custom analytics dashboard and set up triggered workflows based on any event type of your choice. Be notified of successful delivery, clicks, spam complaints, and more.
Review your webhook history
See all POST requests, including retries, sent to your endpoint URL in the past 7 days. Monitor webhooks’ payload data for discrepancies, then disable or delete your webhooks when necessary.
Pick an event type to suit your use case
Choose from Delivery, Soft bounce, Hard bounce, Open, Click, Unsubscribe, Spam complaint or select them all. Create webhooks to:
