How many times does a segmentation rule run?

A segmentation rule is a type of rule that allows marketers to segment their prospects based on specific criteria, such as field values, activities, or scores. A segmentation rule runs only once, as soon as the user completes the rule creation process. The rule will not run again, unless the user manually re-runs it or schedules it to run at a later date. A segmentation rule does not run continuously, up to five times, or as many times as the user specifies when they create the rule1.
