Why We Built ThisYou had customer lists. Good ones—uploaded from your CDP, segmented by behavior, purchase history, loyalty status. But each list lived in its own silo. Want to target “high-value customers who also browsed electronics”? You’d need to manually cross-reference lists and upload yet another one. Audience upload got you started. Combined Lists get you to precision.

What Changed

You can now create audiences by combining your existing uploaded customer lists—no more re-uploading or manual merging. From the new Audience Hub, hit New Audience → Create Audience from Lists to open the Audience Builder.

The builder uses include and exclude blocks to give you full control over who ends up in your audience:
  • Include blocks: Add up to two include groups, each with up to 3 uploaded lists. Within each group, choose Any (union) or All (intersection) to control how lists combine. Groups are connected by OR.
  • Exclude block: Optionally exclude users from up to 3 lists. Anyone in the exclude list is removed from the final audience.

​
What You Get

  • Visual audience builder: Combine lists with include/exclude logic—no CSVs or spreadsheets needed
  • Flexible logic: ANY (union) or ALL (intersection) within include blocks, OR between blocks, and exclusion support
  • Up to 3 lists per block: Layer multiple segments for precision targeting
  • Audience Hub: See all your audiences—uploaded and combined—in one place, with source type clearly labeled
  • Campaign-ready: Combined audiences show up in the campaign creation flow just like uploaded lists

​
