Exporting Unsubscribes and the Durable Unsubscribe List?
Is simply exporting the Unsubscribed System SmartList enough?
According to this article on Durable Unsubscribe, Marketo "has a master email status, which is separate from the unsubscribe flag visible on the lead detail record....When a new lead is created, we check it against the master email status table." This sounds like the list should cover all historical and deleted leads.
Should I be exporting the Durable Unsubscribe Master list instead?
