I have a smart campaign running to capture any lead that hard bounces 3 consecutive times. My initial thought is to set up a flow that automatically deletes these hardbounces from our Marketo instance (no point in having them sit there counting against our license limits).
However, I understand that once we delete the lead, we lose all data that came in with it (e.g., acquisition program, etc).
Is there a best practice for dealing with leads/emails that you know are hard bouncing? Does it make sense just to black list them, or would deleting them be the better way to go? If you choose not to delete them, but black list them instead, will the lead still count against your license?
Thanks,
Steve
