How Do You Segment Audiences in Salesforce Marketing Cloud (SFMC)?
Build smart, compliant segments that power personalized journeys. This guide shows how to model data in Contact Builder, choose Lists vs. Data Extensions, and use Filters, SQL, and Decision Splits to activate audiences across Email Studio, Journey Builder, and Mobile.
In SFMC, audience segmentation starts with a clean data model in Contact Builder: define a unique Contact Key, relate Data Extensions via Attribute Groups, and sync CRM objects you need. Build segments using Filter Activities for marketers, SQL in Automation Studio for advanced logic, and Entry/Decision criteria in Journey Builder to keep membership fresh. Always enforce consent and channel preferences, apply exclusions (bounces, opt-outs, recent complainers), and schedule refreshes so programs stay accurate.
SFMC Segmentation Essentials
The SFMC Segmentation Playbook
Follow this sequence to go from raw CRM data to production-grade audiences that stay accurate and compliant.
Model → Ingest → Relate → Segment → Validate → Orchestrate → Govern
- Model the Contact: Choose Contact Key, define primary Data Extensions (Profile, Subscriptions, Preferences), and set required keys/indexes.
- Ingest data: Use Synchronized Data Sources for Salesforce objects; land web events/transactions via APIs or imports; minimize unused fields.
- Relate attributes: Build Attribute Groups in Contact Builder (1:M for activities like email/web, M:1 for account-level traits).
- Create segments: Start with Filter Activities (status, region, lifecycle), then promote to SQL for join-heavy, deduped, or incremental segments.
- Validate & QA: Compare counts to CRM, sample records, verify opt-out logic, and test inclusion/exclusion edge cases.
- Orchestrate: Use Journey Builder Entry Sources targeting your segment DE; apply Entry/Exit criteria and Decision Splits to keep journeys current.
- Govern: Document data lineage, schedules, owners; monitor performance, errors, and data drift with Automation Studio notifications.
