One Subscriber Record for Every Team, Every Channel

Stack9's Customer Data Platform keeps a single, unified subscriber profile — custom fields, preferences, audiences, and a full engagement timeline — so marketing, product, and support teams stop stitching together a CDP, an email tool, and a spreadsheet of custom fields just to know who a customer is.

The Customer Record Every Other Feature Builds On

Unified subscriber profiles

Core attributes — email, name, location, preferences — plus extensible custom fields (text, number, boolean, date) for anything specific to your business, all on one record.

Dynamic audiences and static lists

Build rule-based audiences that update automatically as behavior and attributes change, or curate static lists by hand for a specific send — organized in an audience-to-list hierarchy.

A complete engagement timeline

Email opens, clicks, and bounces; form submissions; campaign participation; journey progression — every touchpoint appends to one customer timeline instead of living in separate tools.

GDPR/CCPA-compliant preferences

Granular, per-subscription-type opt-in/opt-out, a full preference history audit trail, and self-service preference management for subscribers.

Bulk import with built-in data hygiene

CSV import with custom field mapping, automatic duplicate detection and merge, email format validation, detailed error reporting, and job tracking for large imports.

Business Unit-aware scoping

Subscribers, audiences, and lists can be scoped per Business Unit inside one Marketing Tenant, so each brand or team works its own data without duplicating the platform.

From First Touch to Full Timeline

1

Capture

Forms, imports, and API calls create or update subscriber profiles automatically — no separate sync job to maintain.

2

Segment

Define a dynamic audience by behavioral or demographic rule, or curate a static list by hand for a one-off send.

3

Track

Every open, click, form submission, and journey step appends to the subscriber's engagement timeline in real time.

4

Activate

Feed audiences and lists straight into campaigns, journeys, and AI personalization — the same record, everywhere it's used.
