How do I connect Mailcheck?

Sign up for Conductor Deck, then add a Mailcheck step to a workflow on the visual canvas. The builder walks you through the connection it needs — an account authorization or the required keys — right inside the step. No separate setup or code.

What's the difference between a trigger and an action?

A trigger is the event that starts a workflow — for example, a Stream Deck button press or an incoming event from a connected app. An action is a step the workflow performs once it runs. A workflow is one trigger followed by one or more actions.
