We have a similar issue. We had an Operational program in Marketo that went off the rails (wrong logic in the smart campaign) that accidentally deleted some records from Marketo but left them in sfdc. I would like to push those people (Contacts) back from sfdc into Marketo. If I create a report in sfdc and add them to a campaign in sfdc, will that trigger the Marketo Sfdc sync and push the leads back into Marketo?
If not, would you recommend I re-upload these people back into a list in Marketo to trigger the sync?
