Segments
Named audiences shared across campaigns and the API. See Features › Segments for how a campaign uses one.
| Column | Meaning |
|---|---|
| Name | Name (unique per app) and description. |
| Definition | The definition in one line, as the wizard's summary shows it. |
| Devices | Devices that matched at the last count — reachable ones only (opted in, valid token). |
| Updated | Last edit. |
- New segment opens the builder in a dialog: name, description, and the same field / operator / value tree as the wizard, including tag suggestions and the Interaction (behavioural) condition. The segment is counted on save.
- Count re-counts now and updates the number. Counts are never automatic; a saved segment's size is a snapshot.
- The pencil edits. A change here does not reach campaigns already scheduled or active — they copied the definition when they were sent. New campaigns picking the segment get the new definition.
- Delete deletes. A draft still pointing at it fails at send with
404.
In the wizard, the audience step has a Saved segment… picker and, for an ad-hoc tree, Save as segment.
