# Segment

Segments are a feature in the Apps in Toss console that lets you create and manage user groups that match specific conditions. You use it when you want to send messages only to specific users, such as for marketing or sending notifications.

***

### What are the benefits of using segments?

* You can target precisely. You can send messages only to users who match the conditions you want.
* You can do data-driven marketing. You can design campaigns based on users' behavior and characteristics.
* You can improve the user experience. By providing personalized messages, you can increase engagement and satisfaction.

**Condition categories provided**

You can combine conditions from four categories: transaction information, user information, user activity, and user profile.

* **Transaction information** — Information related to users' actual transactions, such as the brand in transaction history, ad category, and whether Toss Pay was used.
* **User information** — Basic user attributes such as age, gender, credit score, app version, and carrier.
* **User activity** — Based on activity history within the app. Not mini app login **access criteria**can only be set.
* **User profile** — Information that comprehensively analyzes a user, such as financial tendencies, lifecycle stage, and inferred interests.

{% hint style="info" %}
**Please note**

* You can combine multiple conditions **with AND or OR conditions**and use them together.
* If you use target sampling, you can adjust the number of users included in the segment.
* Even if you delete a segment you created, you cannot create another segment with the same name again.

**2. Set category and conditions**

Select the desired category and subconditions **'Add'** and it will be added to the right **'Selected segments'** screen.

* If there is only one condition, you can save it right away by pressing **'Save'** .
* To use multiple conditions together, add all the desired segments and then **'AND'** or **'OR'** set the condition.
* Some segments that require prediction need accuracy settings.
  * Increasing accuracy may reduce the segment size (population).
  * If population size is important, you can lower the accuracy. However, targeting accuracy may decrease.
  * For general use, set it to 50% or higher.
