This idea has been merged into another idea. To comment or vote on this idea, please visit JETO-I-51 Add a status for launched campaigns.
When Marketo admin activates the campaigns in Marketo, update the status on the campaigns dashboard to "In progress" or "Active" or "Running" and when the last campaign has run, update to "Completed" or "Finished"
I think in addition to the "Approved" status, a "Completed" would help manage workflow.
