Data strategy, subscriber keys and segmentation design

How a consultant turns data requirements into a strategy: database of record first, only the data campaigns use, keys and links that hold together, channel-aware opt-outs, attribute groups and populations, and data feeds that stay fresh.

Official exam objective
Demonstrate how to gather requirements in order to put together a data and segmentation strategy for the customer.

~8 min read · 16 practice questions ·

What the exam expects

  • Gather data sources and pick the database of record before designing anything else.
  • Decide which fields to import from what campaigns will segment or personalize on, and keep unneeded sensitive data out.
  • Identify foreign, primary and contact keys, and spot key strategies that will break (channel-bound values, digit collisions, shared household emails, internal IDs).
  • Recommend attribute-group, population and link designs, and explain that an Email Studio unsubscribe doesn't reach other channels.
  • Plan how data stays fresh: scheduled imports, and synchronized CRM data copied into sendable, shareable data extensions.
  • Key terms: DBOR (database of record: source of truth for opt-in status and subscriber info); contact key (unique contact identifier, the subscriber key in Email Studio); foreign key (fields that connect two tables); primary key (unique row identifier); attribute group (linked data extensions); population (a large, distinct group of contacts).
