Which phase of the Mbox process modifies the page content?

The phase of the Mbox process that modifies the page content is the Mbox response phase. During this stage, the server sends back data to the client (the web browser) about which content needs to be displayed on the page. This includes the targeted variations that have been defined, allowing for an immediate update of the page's content based on user segmentation or other targeting criteria. The response from the server dictates how the content will appear to the user, enabling personalized experiences based on analytics and targeting strategies implemented in Adobe Target.

In contrast, the other phases focus on different aspects of the Mbox process. Mbox delivery involves the transmission of Mbox requests to the server, while Mbox return deals with data retrieval from the server. Mbox result, on the other hand, pertains to the outcomes after the user has interacted with the Mbox, including conversion tracking or performance metrics rather than direct page content modification.
