# Segment

The `Segment` family — 7 operations.

A segment is a saved audience — a named group of shoppers for marketing and outreach. A static segment is curated by hand with the add/remove member actions; a dynamic segment stores a rule (interests, loyalty tier, consent purposes, preferred locations, upcoming birthdays, purchase history) and re-materializes its membership each time you refresh it, with manual exclusions subtracted after matching.

## Operations

| [deactivateSegment](/reference/segment/deactivateSegment/) | mutation | Stage a segment — it stays editable but marked inactive. |
| [doomSegment](/reference/segment/doomSegment/) | mutation | Permanently retire a segment — its membership list dies with it. |
| [reactivateSegment](/reference/segment/reactivateSegment/) | mutation | Bring a staged segment back to active. |
| [segment](/reference/segment/segment/) | query | Look up one customer segment. |
| [segments](/reference/segment/segments/) | query | Your organization group’s customer segments, newest first. |
