I accidentally deleted running smart campaign (like 10 min after it was run). I'm not sure if it has already qualified all leads or not. Now I don't see this campaign in campaign queue. What happened with the leads in this campaign?
I suspect the leads ran through. Try a smart list either with the original list, if possible, or use MEmber of Smart Campaign, which may or may not work.
You can ask Support or check the Audit Trail to see if you can recover some details.
