Since Cvent doesn't have a opt out by item, we would update the text at the bottom to send an email to the team requesting to opt-out. This allowed our team to explain that once they opt-out that no further emails would be sent and they would miss out on important event specific emails. Additionally we added the section to join specific contact lists (for classic, I am not sure that this has been enabled in Flex). This would allow each participant to select the "emails" they wanted to receive from us about the event. Then we would use those contact lists to send emails from. Not the easiest work around, but hopefully Cvent will bring out an opt-out based on specific items or a manage emails section for events.
