How do I add event webhooks for email delivery status?

To add event webhooks for email delivery status, the general steps are:

1. Create a webhook endpoint on your server

   • Set up an HTTPS endpoint that can accept POST requests.
   • Make sure it returns a fast 2xx response.
   • Example: https://yourdomain.com/webhooks/email-status

2. Register the webhook in your email provider

   • In your email service dashboard or API, add the URL of your endpoint.
   • Select the events you want, such as:
     • delivered
     • opened
     • clicked
     • bounced
     • dropped
     • spam_reported

3. Verify webhook authenticity

   • Most providers sign webhook payloads with a secret.
   • Validate the signature on each request to ensure it came from the provider.

4. Parse and handle the event payload

   • The webhook body usually includes:
     • event type
     • message ID
     • recipient
     • timestamp
     • reason/failure details, if any
   • Update your database or trigger workflows accordingly.

5. Test with a sample event

   • Send a test notification from your provider’s dashboard or API.
   • Confirm your endpoint receives and correctly processes it.

Example webhook handler

app.post('/webhooks/email-status', express.json(), (req, res) => {
  const event = req.body;

  switch (event.event) {
    case 'delivered':
      // mark message as delivered
      break;
    case 'bounced':
      // mark message as failed
      break;
  }

  res.sendStatus(200);
});
