This feature can be used for "conditional" automated programs with steps like the following where a list/segment needs to be a reference list (i.e., condition):
- First step is to wait some amount of time (typically an hour)
- Second step is a Conditional “If Contact in Marketing List” step
- Third Step is “Go to Another Step” – which is the Wait Step
Take care when doing this, because contacts who do not match the conditional step can get caught in an endless loop, and cause the program data to grow unbounded.
Instead of using the "allow contacts to repeat previously executed steps..." feature, you can use the Wait Until in List/Segment step. This will allow the automated program to reference another list/segment before allowing a contact to move forward to the next step.
