Flows and Channel Actions: How They Work

To use channel actions at their full power, you must understand how channel actions function when used inside different Flows. Flow types have specific goals. Some perform clear functions, like sending one time blasts. Others are for broader goals, like keeping audiences in sync between two systems.

As a result, flow types inherently determine what a channel action can accomplish. This logic varies depending on the flow.
