Master Smartlists (or other idea?)
Hello, I am trying to develop master audiences (to use a word without implied system meaning). The goal is to consistently target specific messages to the same audience without having to rebuild the criteria time and time again. Because I work best with examples...if my target was teachers I would have master audiences for preschool teachers, elementary school teachers, middle school teachers and high school teachers because I know for my content, I really need to target by AT LEAST that first.
I initially set this up with Smartlists in the lead database with the thought that when building smart campaigns I would use filter criteria like "is member of preschool teachers smart list." However these take years it seems to load. Is this not the way group smartlists are meant to be used? Is there a different Marketo feature I should use instead? Or is the answer just to be more patient?
