How can I sync past unsubscribes into SFDC?
Hi! We are a newer Marketo customer and have realized that our SFDC was blocking Marketo unsubscribes from syncing with the email opt-out field in SFDC. We've since undone the block and new unsubscribes are being reflected on the SFDC contact record. Now how do I go back and get all the unsubscribes that happened before this fix to sync into SFDC? TIA!
