Dynamically add users to list within a workflow.
{{...}}
.
List will only be created if the Create list if it doesn't exist
setting is ON.
One common use case of creating list dynamically is when you need to create different lists based on user topic subscription. e.g., there are multiple events happening and you want to create a separate list for each event. List ID in such case can be {{event_id}}_subscribers
and List name {{event_name}} - subscribers
.
