## Identify

If you aren't familiar with the Segment Spec, take a look at the [Identify method documentation](/docs/segment/connections/spec/identify/) to learn about what it does. An example call would look like:

```js
analytics.identify('userId123', {
  email: 'john.doe@example.com'
});
```

Segment sends Identify calls to Ninetailed as an `identify` event.

Use Identify calls to associate traits with a user with which can be used for personalization in email campaigns or website components.

## Track

If you aren't familiar with the Segment Spec, take a look at the [Track method documentation](/docs/segment/connections/spec/track/) to learn about what it does. An example call would look like:

```js
analytics.track('Login Button Clicked')
```

Segment sends Track calls to Ninetailed as a `track` event.

With the Ninetailed Audience Builder, create experiences for visitors who have performed a special action, like `signup` or `registered_for_newsletter`.

## Engage

You can send computed traits and audiences generated using [Engage](/docs/segment/engage) to this destination as a **user property**. To learn more about Engage, schedule a [demo](https://segment.com/contact/demo).

For user-property destinations, an [identify](/docs/segment/connections/spec/identify/) call is sent to the destination for each user being added and removed. The property name is the snake\_cased version of the audience name, with a true/false value to indicate membership. For example, when a user first completes an order in the last 30 days, Engage sends an Identify call with the property `order_completed_last_30days: true`. When the user no longer satisfies this condition (for example, it's been more than 30 days since their last order), Engage sets that value to `false`.

When you first create an audience, Engage sends an Identify call for every user in that audience. Later audience syncs only send updates for users whose membership has changed since the last sync.

> \[!NOTE]
>
> Real-time audience syncs to Ninetailed by Contentful  may take six or more hours for the initial sync to complete. Upon completion, a sync frequency of two to three hours is expected.
