Segments
Build live audiences from traits, events, campaign engagement, and channel opt-ins.

How segments work
A segment is a live query over unified profiles. Combine AND/OR conditions on attributes (city, LTV), events (Purchase in last 7 days), and reachability (email subscribed, WhatsApp opted in).
Use segments everywhere
The same segment can power a WhatsApp campaign, an email journey, an on-site popup, and inbox routing. You do not rebuild audiences per channel.
