How do single-send journeys utilize data extensions?

Single-send journeys in Salesforce Marketing Cloud make use of data extensions primarily to store audience information for sends. Data extensions are essential in this context as they allow marketers to segment and manage their audience effectively. By storing relevant audience details—such as demographics, preferences, and behaviors—data extensions facilitate targeted communications and personalize messages sent through the journey.

This capability to organize and retain audience data helps ensure that the right content reaches the right individuals, thereby enhancing engagement and response rates. Marketers can create tailored experiences based on the information stored in these data extensions, ultimately driving better results from their single-send campaigns.

Other choices do not align with the primary function of data extensions in the context of single-send journeys. For instance, schedule send times and validation information are not typically managed through data extensions, and baseball card information does not pertain to the functionalities offered by Salesforce Marketing Cloud.
