Good to know Dan. Are you aware if there is a limit to how many active engagement programs you can have or a limit to how many you can have in general?
Last I heard it was 100 ACTIVE engagement programs. But even if you deactivate them (which you should do, and not delete, if no longer needed - so that you can still report on them), this still goes against that count (unless Marketo has fixed this). Each time we hit our limit, Marketo extends our limit in our instance.
