# Segments

Segments are reusable audience definitions.

They group users by rules (behavior, profile, responses, tags, location, time).

Use segments in campaigns, journeys, and analytics.

{% hint style="info" %}
If you’re building an audience for a campaign or journey, you want a **rule-based segment**.

### Quickstart: build a segment you can target

{% stepper %}
{% step %}

#### 1) Start with the question you want to answer

Examples:

* “Who added to cart but didn’t purchase?”
* “Who opened the app 3+ times this week?”
* “Who did not click my last campaign?”
  {% endstep %}

{% step %}

#### 2) Choose the segment type

* **Rule-based**: dynamic and rule-driven. Default choice.
* **Ready to use**: pinned segment for common targeting.
* **Connector segment**: synced/imported from an external tool.
  {% endstep %}

{% step %}

#### 3) Define criteria (keep it minimal)

Common criteria building blocks:

* **Behavior / event** (performed / not performed, recency, frequency)
* **Profile attributes** (tier, language, city)
* **Response** (received/opened/clicked/not clicked)
* **Tag** (static labels)
  {% endstep %}

{% step %}

#### 4) Save and generate

Name it like a query: `cart_abandoners_24h` or `high_value_buyers_30d`.
{% endstep %}

{% step %}

#### 5) Use it in targeting

Segments are selectable in:

* Campaigns (Who/Targeting)
* Journeys (Audience)
* Analytics filters
  {% endstep %}
  {% endstepper %}

### Key concepts (fast)

* **Rule-based segment**: recalculated from rules (optionally daily).
* **Ready to use segment**: pinned and shared for repeat targeting.
* **Connector segment**: synced in from an external tool.
* **Predictive segment**: AI-based segment that predicts likelihood of an event.
* **Tags vs segments**: tags are labels. Segments are rules.
