In order for a campaign to message customers appropriately, the campaign must target customers by associating the campaign to the appropriate:

• Conversation to determine the superset of customers that will be targeted

• Audience to determine the smaller group of customers in the conversation that will be messaged

• Segmentation to determine what groups the customers are divided into in order to deliver a customer-appropriate message

• Suppression List to remove email addresses that should not be messaged under any circumstances

Because customer interests and mail permissions are dynamic, it is important to associate all three customer targeting groups any any suppression lists to the campaign to ensure that customers are targeted or not messaged as appropriate. Over the course of campaigns, a customer's behaviour and interests may move them in and out of conversation, audience and segmentation groups. as well as suppression lists The conversation, audience and segmentation models and suppression lists manage the change of customer status in order to best serve the customers in campaigns.
