In Pega Customer Decision Hub, campaigns provide an additional mechanism to deliver actions to customers and monitor the action performance.
Before the introduction of Next-Best-Action Designer and the Next-Best-Action strategy framework, campaigns were the main mechanism by which actions were delivered to customers. In newer versions of the product, this functionality has been superseded by the practices of 1:1 Customer Engagement, embodied within the product through the use of Next-Best-Action Designer. As a best practice, you should configure your customer engagement strategy in Next-Best-Action Designer, as described in Improving customer experience with next-best-action on owned channels.
The following links are provided for reference for users who have already configured campaigns in an earlier version of their Pega Marketing application.
