# List segments

Retrieve all segments with tag rules and active subscriber counts.

Source: https://statusdashboard.com/docs/api/subscriptions/segments/list

`GET /app/segments`

Returns org segments with resolved tag names and read-time active subscriber counts.

Requires the `admin` or `event` role and the organization **segments** feature. Event operators use this list when configuring segment include/exclude targeting on an event. Create, update, delete, tag, and registry endpoints remain admin-only.

`activeSubscriberCount` is computed at read time by intersecting registry contacts with currently active email subscribers — it does not define registry membership.
