An Audience is a group of contacts that have something in common.
You can use audiences within a campaign to decide which group(s) of contacts should receive an email.
For integrated users, your CRM categories automatically sync with ActivePipe and provide matching Audiences for you to use when building campaigns.
To view a list of all your audiences, simply navigate to the Audiences menu, found at the left of your screen.
