What is a Segment?
A Segment is a group defined by rules that updates itself as your customers change.
A Segment is a group of people defined by rules rather than by hand — for example, "customers in Germany who bought in the last 30 days."
In plain terms
A Segment is a smart filter. You describe the kind of person you want to reach, and Zalify keeps the group up to date for you. Nobody is added or removed manually — the rules decide, and the membership re-checks itself as people's behavior and details change.
Why it matters
Segments let you target by what people do, not just what they signed up for. That's where relevant marketing comes from:
- "Subscribers who haven't opened an email in 60 days" → a win-back campaign
- "Bought once, never came back" → a second-purchase nudge
- "High spenders" → early access to a new drop
Because a segment updates itself, someone drops in or out automatically the moment they match — or stop matching — your rules.
Why segments are "dynamic"
The word to remember is dynamic: a Segment is always live. Set it up once and it stays current forever, no maintenance. That's the opposite of a List, which only changes when you or the customer act.
How it connects
Segments are built from the profile and behavior data Zalify collects — including details from Submissions and signals from Events. Like a List, a Segment can be the audience for a campaign.
Segment vs. List
Use a List for a fixed group you gather on purpose ("newsletter subscribers"). Use a Segment for a living group based on behavior ("active buyers this month"). Many stores use both together.
