Before you begin
- A configured schema. Open an existing audience or start a new one.
What Insights shows
Understand and validate the size, composition, and characteristics of your audience using Insights. While defining or editing an audience in Customer Studio, you can view summary metrics, compare overlaps, and break down key traits inside the visual builder. Insights analyzes a single audience while you build it: who’s in it right now, how it’s composed, and how it overlaps with other audiences. To watch an audience change after it’s live, use its overview. For analysis that spans campaigns, use Intelligence, a separate product with charts, metrics, funnels, and experiments, built on the same customer data.Access audience insights
You can access insights while creating or editing an audience in two places:- In the audience creation flow, during the Define audience step

- In the audience builder, under the Definition tab

Calculate audience size
For the overall audience count and a spot-check of members, use Build an audience. Insights adds size views the top-level count doesn’t show. Calculate the size of a specific filter group by selectingCalculate size within any top-level AND block. This shows how each filter group contributes to or reduces overall audience membership.


If sampling is enabled on your data models, preview results in the audience
builder may be returned using sampled data for faster performance. Learn more
about sampling.
Member preview
Click the size preview count to more closely inspect the list of members who currently meet your audience criteria and ensure you’re building the correct audience. If you’ve chosen to redact any columns in your model configuration, they are redacted here.


Audience overlaps
With many audiences syncing simultaneously, it can be difficult to ensure that end users aren’t being targeted by multiple campaigns. Audience overlaps help you validate the composition of your audiences by letting you compare one audience against another. You can find audience overlaps within the Insights panel when defining your audience. Select a previously created audience from the dropdown to compare the audiences.
Audience breakdowns
Breakdowns help quickly check your audience segmentation and ensure the audience meets your needs by enabling you to better understand the distribution of specific characteristics within audiences. Breakdowns help you explore how an audience is distributed across key traits or metrics—for example, how many users fall into each region, loyalty tier, or spending bucket. To create a breakdown:- Open the Insights panel.
- Go to the Breakdowns tab.
- Choose a metric or property, such as:
- Saved metrics (custom metrics from your workspace)
- Events (e.g., Bookings)
- Relations (e.g., Preferred Hotel)
- Properties (e.g., Region, Language)
- Traits (custom trait columns)
Total Bookings by Region) and choose an aggregation type (e.g., count, average).
Breakdowns are shown as charts within the panel, helping you visually validate whether your audience reflects your desired segmentation.

Numerical metrics
When you select a numerical property or a model-based metric (e.g. events), you can optionally select a non-numerical user property to group the metric by.
Except in the case of
Saved metrics, if no Group by option is selected, the chart will group by the metric itself.
Depending on the type of numerical metric you select, you are able to choose additional options on what to view in your breakdown.
Total events vs. unique users
When a breakdown uses a related or event model, you can choose how to count it:- Total events: every occurrence, including repeats by the same person. Use this to measure volume. For a related model that isn’t an event model, this option is Total rows.
- Unique users: the number of distinct people with at least one occurrence. Use this to measure reach. The label uses your parent model’s name for its records, for example Unique customers.

Further exploration
To explore a breakdown in more depth, you can open it in Charts to apply additional filters and groupings, explore different visualizations, and save the chart for future reference.
