How can I track the status of emails sent from a Cloudflare Worker?

Tracking email status (sent, delivered, bounced, opened) requires integration with your chosen email sending service (ESP). Most ESPs provide APIs or webhooks that allow you to retrieve email event data. Your Cloudflare Worker can call these APIs or listen for webhooks to update your application's database or trigger further actions based on email status changes. You'll need to handle the API authentication and data parsing within your Worker.
