I have an RSVP landing page for an event and we only have limited space available. I want to trigger acceptance emails to the first X people, wait list emails to the next Y people, and RSVP declined emails to the remaining Z people. FYI - the RSVP's are coming through an integration with Instapage, so they are getting added to my Marketo instance via a static list.
Does anyone have a solution to this? Maybe you have some ideas Grégoire Michel??
