Deleting Dynamics CRM Synced Leads
We currently have a number of leads synced over from Dynamics CRM that have been verified as having BAD EMAIL addresses in CRM.
I understand the process for running an operational cleanup campaign for these leads within Marketo.
However, should I also set the Sync to Marketo field as FALSE so that these Bad Email leads do not resync back in Marketo?
Is this best practice?
Thanks,
Jeremy
