# Segment types

EARLY ACCESS

Customer Profiles provides two types of segments:

1. **Predefined segments**
2. **User-defined segments**

___

## Predefined segments

**Predefined segments** are **automatically available** in Customer Profiles.

The following predefined segments are available:

- **Active mobile users** - Uses the App Launch event that has happened more than or equal to 1 time in the last 30 days
- **Inactive mobile users** - Uses the App Launch event that has not happened more than or equal to 1 time in the last 30 days

Note
These segments **automatically** update based on user activity. You **cannot** edit or delete predefined segments.

___

## User-defined segments

**User-defined segments** are custom segments that you create based on specific criteria. They give you complete control over your segmentation strategy.

You can create segments based on:

- **Person attributes** (such as location, demographics, [custom attributes](https://www.infobip.com/docs/customer-profiles/configuration/person-custom-attributes))
- **[Events](https://www.infobip.com/docs/customer-profiles/events)** (such as purchases, page views, app launches)
- **Combinations of attributes and events**

You can edit and delete user-defined segments **unless** they are currently used in active Journey campaigns.

To create user-defined segments, see [Create a segment](https://www.infobip.com/docs/customer-profiles/segments/create-a-segment).
