Which option best describes how Engagement Programs function?

Engagement Programs are designed to nurture leads through a series of targeted emails over time, making the option of nurturing leads the most accurate description of their function. These programs allow marketers to create a structured approach to delivering content that is relevant to the recipient's interests and behaviors. By providing valuable information incrementally, Engagement Programs help to guide leads along the buyer's journey, maintaining engagement and fostering relationships until they are ready to make a purchase decision.

While time zones, A/B testing, and transactional emails may play roles in broader marketing strategies, they do not encapsulate the primary function of Engagement Programs. The emphasis is on a continuous delivery of content rather than isolated tests or transactional communications, which are typically more focused and time-sensitive.
