Build segments by existing segments

Segment-based filtering allows you to include users who already belong to one or more existing segments. This lets you reuse previously defined logic instead of recreating complex conditions from scratch, making it easier to build layered audience targeting.

To build a segment using existing segments:

1. When creating a new segment, click Add filter by → Segment.

2. Select one or more existing segments to include in your new segment.

3. If you add multiple segments, choose how they should be combined using a logic operator:

   • Select AND to include users who belong to all selected segments
   • Select OR to include users who belong to any of the selected segments

Enable this option to target a user across all their devices, not just the one that matched the segment condition. This ensures they receive your messages on every platform they use.

• Enabled: If any of the user’s devices meet the condition (for example, purchase event, tag, behavior), all their devices across platforms are included in the segment.

• Disabled: Only the devices that meet the condition are included in the segment.

Below are practical scenarios showing how to use existing segments to create more targeted audiences.

Goal: Target only premium subscribers who are recently active.

How to set up:

• Segment filter: Select Active Users (users who opened the app in the last 7 days)
• Tag filter: subscription_type_premium is true
• Operator: AND

Use case: Send exclusive offers or premium feature announcements to engaged, paying users.

Goal: Target users who belong to either high-value customers or recent purchasers.

How to set up:

• Segment 1: Select High-Value Customers
• Segment 2: Select Recent Purchasers
• Operator: OR

Use case: Run promotional campaigns targeting users with demonstrated purchase behavior from multiple angles.

• Reuse well-defined segments to maintain consistency across campaigns and reduce setup time.
• Combine segment filters with tags or events for more precise targeting.
• Keep track of segment nesting levels to avoid hitting the five-level limit.
• Regularly review and update base segments to ensure derived segments remain accurate.
