What type of Information do rule step types look for in engagement studio programs?

Rule step types in engagement studio programs are used to check the prospect criteria, such as field values, list membership, tags, grades, scores, etc. Rule steps can branch the program based on whether the prospect meets the criteria or not. For example, a rule step can check if the prospect has a certain job title or industry and send them different emails accordingly. Prospect interest, behavior, and activity are not rule step types, but they can be used as criteria for rule steps. References Engagement Studio: Rule Steps
