Segmentation
What the domain covers
Segmentation is the practice of dividing a contact population into groups that share traits or behaviors so messaging can be targeted. The candidate must understand segmentation criteria types (demographic, firmographic, behavioral, lifecycle, and value-based), static vs. dynamic segments, segment logic (AND/OR/NOT, nesting), and how segments interact with suppression and consent.
Concepts to master
- Static segments (a fixed snapshot) vs. dynamic segments (re-evaluated as data changes).
- Boolean logic: AND narrows, OR broadens, NOT excludes; nesting changes meaning.
- Lifecycle segments: new, engaged, dormant, at-risk, and how they drive different plays.
- Suppression: segments must respect opt-outs and do-not-contact rules.
- Overlap and exclusivity: contacts in multiple segments, and priority ordering when they are.
Traps in questions
Common traps include treating OR as if it narrows a segment (it broadens), and forgetting that a dynamic segment updates automatically while a static one does not. Another trap is ignoring suppression - a perfectly targeted segment still must exclude opted-out contacts. Questions may also test whether a contact can belong to multiple segments at once (usually yes) and how priority resolves conflicting messages.
Worked example
Build a segment: lifecycle = engaged AND (industry = retail OR industry = hospitality) AND NOT unsubscribed. Rule of thumb: read the logic left to right, but evaluate the NOT first - exclusion is applied last in plain language but removes contacts regardless of where the group sits. Verify the count drops when you add the AND clauses and rises when you swap AND for OR.
Key points
- AND narrows; OR broadens; NOT excludes.
- Static segments are snapshots; dynamic segments update.
- Suppression and consent always apply.
- Contacts can belong to multiple segments.
- Priority ordering resolves overlapping campaigns.
- Lifecycle segments drive distinct engagement plays.
