Customer Data Platform

Stack9 Experience Customer Data Platform creates a unified view of every customer interaction across all touchpoints. From initial form submission to email engagement and purchase behavior, it provides the foundation for personalized marketing experiences and data-driven customer insights.

What is Customer Data Platform?​

Stack9's Customer Data Platform provides three integrated systems that work together to create comprehensive customer intelligence:

  • ✅ Subscriber Management - Unified customer profiles with extensible attributes and preferences
  • ✅ Audiences & Segmentation - Dynamic audiences and static lists for precise targeting
  • ✅ Engagement Tracking - Complete timeline of customer interactions across all channels

This unified approach ensures every marketing touchpoint contributes to a complete understanding of each customer, enabling sophisticated personalization and targeted marketing campaigns.

Subscriber Management​

Unified Customer Profiles​

Subscribers represent the core customer entity with comprehensive profile management:

  • Core attributes - Email, name, location, and communication preferences
  • Custom fields - Extensible attributes for business-specific data
  • Subscription status - Active, inactive, and preference management
  • Profile timestamps - Track when customers joined and last activity

The platform maintains a single source of truth for each customer, aggregating data from forms, email engagement, website behavior, and external integrations.

Active/Inactive States and Communication Control​

Sophisticated status management provides granular control:

  • Active subscribers - Receive all applicable marketing communications
  • Inactive subscribers - Maintain profile data but exclude from marketing
  • Subscription preferences - Granular control over communication types
  • Suppression integration - Automatic compliance with unsubscribe requests

This enables respectful marketing practices while maintaining valuable customer data for analytics and re-engagement opportunities.

Custom Attributes and Business-Specific Data​

Extensible profile architecture supports any business model:

{
  "email": "customer@example.com",
  "name": "John Smith",
  "custom_fields": {
    "industry": "Technology",
    "company_size": "50-200",
    "job_title": "Marketing Director",
    "annual_revenue": "$5M-$10M",
    "product_interests": ["Analytics", "Automation"]
  }
}

Field types supported:

  • Text fields - Names, job titles, company names
  • Number fields - Revenue, employee count, scores
  • Boolean fields - Feature interests, qualification flags
  • Date fields - Renewal dates, important milestones

GDPR/CCPA-compliant preference management:

  • Subscription types - Different communication categories (newsletters, product updates, events)
  • Granular consent - Per-subscription type opt-in/opt-out
  • Preference history - Audit trail of all consent changes
  • Self-service management - Subscriber-controlled preference updates

Engagement History and Customer Timeline​

Complete interaction timeline provides context for every customer:

  • Email engagement - Opens, clicks, bounces across all campaigns
  • Form submissions - Lead generation and profile updates

  • Journey progression - Where customers are in automated workflows

API Reference: Subscriber management uses /marketing_subscribers, /marketing_subscribers/{id}, /marketing_subscribers/search, and /marketing_subscribers/import endpoints with comprehensive profile management, custom field support, and bulk operations.

Audiences & Segmentation​

Dynamic Audiences vs Static Lists​

Stack9 provides two complementary segmentation approaches:

Dynamic Audiences - Auto-updating segments based on rules:

Industry = "Technology" AND Company Size > 100 AND Last Engagement < 30 days

Static Lists - Manual curation for specific campaigns:

  • Event attendee lists

  • Partner contact lists
  • Custom campaign targets

Real-time Segmentation Rules​

Dynamic audiences update automatically based on:

  • Behavioral criteria - Email engagement, form submissions, website activity

  • Engagement recency - Last email open, click, or interaction
  • Campaign participation - Specific campaign engagement or conversion
  • Custom field values - Any business-specific attributes

Audience Hierarchy and Organization​

Structured organization enables sophisticated targeting:

Audience: "Technology Companies"
├── List: "SaaS Prospects" (500 subscribers)

This hierarchy allows:

  • Broad targeting - Send to entire audience
  • Specific campaigns - Target individual lists within audience
  • A/B testing - Compare performance across similar segments
  • Permission management - Control access by audience or list
