Another option is to setup an engagement campaign which assigns an attendee to an existing campaign within your CRM system. Rather than operating on a scoring basis (level of engagement/interest), a flag campaign notifies you of attendees who perform a particular activity at an event (requests certain content, checks into a particular session) that means they should be added to, for example, a 'marketing for Product X' campaign. If your follow-up process already has an identifier used in your CRM system, such as a Campaign ID in Salesforce, we are able to maintain this ID across our scoring frameworks.
