Salesforce Connect includes a condition for personalization that allows you to determine whether or not a visitor is a member of a Salesforce campaign.
When configuring a personalization rule in Experience Editor, you can find this condition under the section Salesforce.
In order to configure this condition, you must first select your tenant. This is because the available campaigns depends on the tenant you select.
It is assumed you have synchronized Salesforce campaigns. For information on how to do this, see Salesforce Campaign Synchronization.
