Creating an audience
An audience is a list of named people you want to reach with ads. You create it empty, add contacts, and then sync it to your ad platforms as a custom audience.
Create the audience
Click Audiences in the left sidebar.
Click Create Audience in the top right.

Enter a Name. Pick something you'll recognize later, like the persona or campaign it's for.
Add a Description if you want. It's optional.
Add Tags to group related audiences. You can filter the Audiences page by tag later.
Click Create Audience.

Creating an audience is free. You only use Audience credits when you add contacts to it.
What you'll see on the Audiences page
Each audience gets a row in the table. The Records column shows how many contacts and companies it holds. Then there's one status column per ad platform: Facebook, Google, LinkedIn, Reddit, Pinterest, Microsoft, OpenAI, Taboola and X Ads.
Off: the audience isn't set to sync to that platform.
Not synced: it's set up but hasn't synced yet.
Synced: the audience is live in that ad platform.
Failed: the last sync didn't go through.
Further right you'll find Website visits, the audience's UTM parameter with a copy button, and its Audience Id. Use Tags, Sort and Columns in the toolbar to organize the table.
Next steps
Open the audience and click Add Contacts to fill it. When it has contacts, click Syncs to send it to your ad platforms.
