Which feature allows you to preview content in real-time while creating it?

The feature that allows you to preview content in real-time while creating it is Content Builder. This tool is specifically designed for content creation and management, enabling users to build and edit various content types, such as emails, landing pages, and mobile messages, within a unified interface.

Content Builder offers real-time previews, which make it possible for marketers to see how their content will appear across different devices and email clients as they make changes. This immediate feedback is crucial for ensuring that the formatting, images, and overall design are effective before finalizing the content for distribution.

While Email Studio focuses primarily on email creation and sending, it does not provide the same comprehensive content preview capabilities that Content Builder does. Journey Builder is oriented towards designing customer journeys, and while it allows for some content personalization, it is not specifically focused on real-time content management. Automation Studio is intended for managing automated tasks and workflows, rather than creating and previewing content in real-time. Thus, Content Builder stands out as the ideal choice for this functionality.
