# Preview Dataset

Workspace-managed sample values for merge variables, used to preview how dynamic content renders.

## Why it matters

A realistic dataset lets you see the real shape of an email before shipping, and helps preflight catch unresolved variables.

## Example

A dataset that fills `first_name` with “Mara” so the greeting reads naturally in preview.
