In Marketo, Program Success is calculated from program statuses that are flagged “Success” within the channel definition. When you create a custom channel you must therefore include (and mark as “Success”) at least one status—most commonly named “Responded.” Without a success-flagged status, the Program Success and related ROI metrics cannot be tracked for any program that uses that channel.

A. Local forms are irrelevant to the Program Success calculation; success is derived solely from program statuses.

B. Merely uploading members doesn’t mark them with a success status, so success metrics still would not populate.

C. Updating statuses is operationally important but impossible until a success-flagged status exists; the prerequisite is to create that status.
