# Domain Tracking

Mailgun offers tracking for clicks, unsubscribes, and opens, with optional HTTPS protocol support on tracking URLs. To enable HTTPS, Mailgun uses Let’s Encrypt with HTTP-01 challenges through your existing tracking CNAME record to issue a TLS certificate. This setup also includes support for HTTP Strict Transport Security (HSTS) for enhanced security.

## Get tracking settings

 - [GET /v3/domains/{name}/tracking](https://documentation.mailgun.com/docs/inboxready/api-reference/optimize/mailgun/domain-tracking/get-v3-domains--name--tracking.md): Use to check if open, click and unsubscribe tracking are active/inactive.

## Update click tracking settings

 - [PUT /v3/domains/{name}/tracking/click](https://documentation.mailgun.com/docs/inboxready/api-reference/optimize/mailgun/domain-tracking/put-v3-domains--name--tracking-click.md): Use to turn on/off the click tracking at the domain level.

## Update open tracking settings

 - [PUT /v3/domains/{name}/tracking/open](https://documentation.mailgun.com/docs/inboxready/api-reference/optimize/mailgun/domain-tracking/put-v3-domains--name--tracking-open.md): Use to turn on/off the open tracking at the domain level.

## Update unsubscribe tracking settings
