I face a similar issue : I need to program an automatic Email Send to recipients in a marketing list associated with a CRM Campaign, 7 days before the start date of the Campaign.
This would be used to automatically send a reminder to everyone who said that they would come to a particular event, 7 days before this event. The list of people to remind would be a marketing list in this case.
Would this still require custom code, or is there a completely other way to do that ?
