Defining an exclusion list of customers who opted out of receiving notifications
Use exclusion lists to prevent Pega Customer Decision Hub from initiating outbound actions for a specific set of customer entities. For example, you can set up an exclusion list for customers who opted out of receiving notifications, customers who unsubscribed from your newsletter, or customers whose email addresses are invalid.
If you specify an exclusion list of customers, Pega Customer Decision Hub checks it during action initiation and wait expiration for outbound channels. Actions for customers on the exclusion list are not initiated or continued.
Exclusion lists are not applied to actions that are initiated through real-time containers and inbound channels.
