We'll be holding an event with multiple shows and limited space for each show. For simplicity let's say we have 5 daily shows with 500 attendees capacity for each. We would like to leverage Marketo for registration purposes and tracking purposes, in which the user chooses what event he would like to attend, depending on availability of course. Does Marketo have an integrated solution for such activity, and if not, who is your partner for this type of activity? Preferably we would also like to send out and approval SMS with a unique code.
