Create your first segment

Overview

Segments turn behavioral and trait signals into activation-ready cohorts. Your first segment should combine a time window, at least one event predicate, and an optional trait filter so you can preview counts before syncing.

Steps

1. Open Audiences → Segments → New and choose Rule-based for a visual builder start.
2. Add a time window such as “last 30 days” to bound computation cost and keep previews fast.
3. Layer conditions: for example Purchase count ≥ 1 AND country = DE. Use preview counts to sense-check population size.
4. Save and wire an optional first activation—many teams start with export-only before connecting paid channels.

{
  "segment": "high_intent_checkout",
  "rules": [
    { "event": "BeginCheckout", "window_days": 14, "min_count": 1 },
    { "trait": "email_marketing_opt_in", "equals": true }
  ]
}

Troubleshooting

• Zero members usually means traits are not yet attached to anonymous profiles—verify identify calls fire after login.
• Slow previews often need a narrower window or fewer OR branches; split complex segments across versions.
• If activation jobs fail, open the segment’s delivery log—most issues are missing platform credentials rather than rule logic.
