Newbie here rolling out the Marketo Event Check In App. Am I correct in assuming the check-in app will only mark those who Attend, or can you mark someone as a "no show". We have a follow-up email either way, but I wasn't sure if I could capture those who did not attend through the app, or if that would default to our current process of changing the Lead Status in SF.
You are correct, you will not be able to mark someone as no-show. You will have to go to the program in Marketo afterwards, hit the "member" tab, select all members that are still registered and change their member status globally.
You could also prepare a batch smart campaign that does exactly this and run it after the event.
