# Analytics and Reporting

Airship captures events from last-mile delivery services, so you can track both email statuses and engagement.
## Last-mile Events

Last-mile delivery events appear in [Real-Time Data Streaming](https://www.airship.com/docs/reference/glossary/#rtds) and message reports as  [Custom Email Events](https://www.airship.com/docs/developer/rest-api/connect/schemas/custom-email-events/).

Status events, like `bounce` and `delay`, help you determine whether or not your messages are received by your audience. We also capture `open`, `click`, and `delivery` events so you can track engagement metrics for your email campaigns. For `click`, only HTTP and HTTPS links are tracked.

See [Custom Email Events](https://www.airship.com/docs/developer/rest-api/connect/schemas/custom-email-events/) for a complete list of last-mile events and their properties.

## Custom Events

To add your own custom events to a channel or named user, use the [Custom Events API](https://www.airship.com/docs/developer/rest-api/ua/operations/custom-events/).

## Disable Events

When creating your message, you can disable open and click tracking to preserve your audience's privacy and exclude irrelevant messages from your metrics. You may want to disable open and click tracking for things like transactional messages or messages where you don't have a clear call to action.

See [Creating content](https://www.airship.com/docs/guides/messaging/messages/content/email/email/#creating-content) in *Email content*.
