What is the difference between the Person Was Deleted from SFDC and SFDC Is Deleted filter? They appear to mean the same thing, but return very different results (Person Was Deleted from SFDC is 22X the size of SFDC Is Deleted). My goal is to delete all people from Marketo that were deleted from Salesforce (all time).
"SFDC is deleted" means that the person is currently in a "deleted" status in SFDC. It might still be in the recycle bin.
"Person was deleted" means that the record has been flagged as deleted somewhere in the past. It might have been undeleted since then, but it will be still retrieved by this filter.
