## Static Segments vs. Dynamic Filter Segments

| Segment Type       | Description                                                                                                                                                                      |
| :----------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Static List**    | A fixed list of contacts manually added or uploaded from a CSV.                                                                                                                  |
| **Dynamic Filter** | Automatically evaluates membership in real-time based on rules (e.g. `properties.plan == "pro"`). Contacts enter and leave the segment automatically as their properties change. |

## Creating Segments in the Dashboard

1. In the sidebar, navigate to **Contacts** → **Segments** tab.
2. Click **Create Segment**.
3. Choose a name (e.g. `Active Pro Subscribers`).
4. Define conditions:
   * Condition 1: `properties.plan` equals `pro`
   * Condition 2: `unsubscribed` equals `false`
5. Click **Save Segment**. The subscriber count updates dynamically.

## Targeting Segments in Campaigns

When drafting a campaign, select the segment from the **Segment** dropdown. Only active, non-suppressed contacts within that segment will receive the email.
