-H "x-api-key: mc_live_8f3d9a1c2e4b5d6e7f" \
-H "Content-Type: application/json" \
-d '{
"from": "sender@yourdomain.com",

"html": "<p>Your secure verification code is <b>839201</b>.</p>"
}'
```

### BullMQ Outbound Worker and Webhook Response

Source: https://mailcraft.tech

Shows a BullMQ worker that processes jobs from the 'transactional-queue' and sends email via SES, then the webhook payload it triggers. Use together to understand the queue-to-webhook flow for delivery tracking.

```javascript
// BullMQ Outbound Workers
const worker = new Worker(
  'transactional-queue',
  async (job) => {
    const { to, html } = job.data;
    await ses.send({ to, html });
    // Sync live metrics
    await trackDelivery(job.id);
  }
);
```

```json
// webhook callback response
{
  "event": "email.delivered",
  "data": {
    "messageId": "msg_9a8b7c6d",
    "recipient": "user@domain.com",
    "deliveredAt": "120ms"
  }
}
```
