I'd think they would stay in your SFDC activity history until your SF admin deletes them.
That shouldn't be too hard to do since they follow a standard naming convention. For example, run an activity report for all completed activities assigned to Marketo User (or whatever SFDC user is used to sync your two systems) with a subject that contains "Was Sent Email" then use the data loader or some other tool to delete those activities.
@ Delinda Thnx a ton!
