Actions are Rianus Automation. A subscriber list can have an unlimited number of actions that will run in sequence.
Actions are executed in sequence with a wait time in the middle, by default Rianu uses a wait of a number of days.
The number of days can be 0 which means the action executes right away and then moves to the next action in a sequence.
Currently only days are supported for the wait time. Hours / Minutes are coming soon.
Actions are all colour coded. These colours will be shown in the subscriber list screen so you can see which subscriber is on which action.
