I should mention that contacts sometimes change their mind and register a second time with a different selection of sessions. I want the email to only include the sessions selected during the most recent registration, excluding any sessions selected previously. The list of sessions should contain the session name and the start date and time.
Can anyone please point me in the right direction or share the code to use? I’m pretty sure I should start with “Marketing event registration created,” but I get lost after that. I’m surprised this isn’t better explained anywhere, as it seems like a common need.
