How do I get delivery open and click events back from an email API?

To get delivery, open, and click events back from an email API, you usually need to enable event/webhook tracking in your email provider and then make sure your app can receive those callbacks.

1) Enable tracking in your email provider

Most email APIs have settings for:

• Delivered / bounced / deferred
• Opens
• Clicks
• Sometimes spam complaints, unsubscribe, etc.

Look for settings like:

• “Event Webhooks”
• “Tracking”
• “Message Events”
• “Webhook Notifications”

2) Register a webhook endpoint

Create an HTTPS endpoint in your app that the email provider can call when events happen.

Example:

• POST https://yourdomain.com/webhooks/email

Your endpoint should:

• Accept JSON payloads
• Respond quickly with 200 OK
• Verify signatures/tokens if the provider supports them

3) Make sure you send with the right options

When sending email, many APIs require tracking to be enabled per message or per domain/account.

Common options:

• track_opens: true
• track_clicks: true
• delivery_tracking: true
• tracking_settings: { open_tracking: true, click_tracking: true }

Also note:

• Open tracking usually works via a tracking pixel, so it can be blocked by privacy features.
• Click tracking rewrites links through a tracking domain.
• Delivery events are usually server-side and more reliable than opens.

4) Handle event payloads

Your provider will send events like:

• delivered
• opened
• clicked
• bounced
• complained
• unsubscribed

Store them in your database and associate them with the message ID / recipient.

5) Confirm the basics

If you’re not seeing events:

• Webhook URL must be publicly reachable and use HTTPS
• Your endpoint must return 2xx
• Event tracking must be enabled for the sender/domain
• SPF/DKIM/DMARC should be set up properly
• Opens may be suppressed by Apple Mail Privacy Protection or image blocking
• Click tracking may require branded/custom tracking domains in some providers

6) If you mean “delivery/open/click events from the provider API”

Some APIs let you pull events via an events endpoint instead of webhooks. In that case, check for:

• GET /events
• GET /messages/{id}/events
• GET /activity

You typically filter by:

• message ID
• recipient
• event type
• date range
