A segment is a saved filter. When you send a campaign, you can pick a segment instead of everyone subscribed.
- Open Segments.
- Under "New segment", name it.
- Set any combination of filters: tags, interests, whether they have ordered, customer type, days since last order, minimum spend, or specific products bought.
- Click "Save segment".
The segment list shows how many people currently match it, on email and on text, so you can check the size before you send to it.
