Target by behavior,
not by guesswork.
Reusable audiences defined by behavior and profile — versioned, so you can prove who was targeted.
A saved filter is not an audience.
In most tools a segment is a filter evaluated the moment you press send. Change the rule and the history of who it once matched is gone, so a question as basic as "who received the March re-engagement send?" has no reliable answer.
SendNectar stores a segment as an immutable, versioned definition and materializes the membership for fast targeting. The rule you published is the rule that ran, and it stays queryable after the fact.
Segments, in detail.
Behavioral and profile rules
Combine contact attributes, custom fields, tags, subscription state, and engagement behavior into one reusable audience definition.
Versioned definitions
Segment definitions are stored immutably. Editing produces a new version rather than rewriting the past, so targeting stays auditable.
Materialized membership
Membership is materialized rather than recomputed at send time, so compiling a large audience does not stall a campaign.
Brand-scoped by construction
A segment belongs to exactly one brand and can only ever match contacts within it. There is no cross-brand segment to get wrong.
Reusable everywhere
The same segment targets campaigns, enrolls contacts into automations, and defines an export — one definition, one meaning.
Consent still applies
Matching a segment is not permission to send. Subscription topic state, suppressions, and frequency caps are evaluated independently at compile time.
Segments, lists, and tags — which to use.
Three grouping primitives with different jobs. Reaching for the wrong one is the most common source of audience mess.
- Segment
- Rule-based, versioned, materialized. Use for behavioral and attribute targeting.
- Static list
- Explicit membership with a default opt-in mode. Use for imports and deliberate groupings.
- Dynamic list
- Membership driven by criteria rather than manual add and remove.
- Tag
- Lightweight per-brand label with a color. Use for organization and as an automation trigger.
- Topic
- A consent choice, not a grouping. Determines whether you may send at all.
- Opt-in mode
- single or double, set as the list default
