Which of the following statements is true regarding campaign workflow activities?

The correct statement is that parameters must be set for each activity in a campaign workflow. This is essential because parameters define how each activity operates and what data it uses, which is crucial for the successful execution of the workflow. By configuring these parameters, you ensure that the activities align with the overall campaign objectives, allowing for personalized and targeted actions based on the data available.

In a campaign workflow, while some activities can run independently, many depend on specific configurations to achieve the desired outcomes. Additionally, not all activities require sequential execution, offering flexibility depending on the campaign design. It is also possible to remove or modify activities from a workflow even after they have been added, which enables practitioners to adapt their campaigns dynamically based on performance and feedback.
