I am trying to set up the smartlist of a smartcampaign using advanced filters. i have 5 filters in the smartlist. I want to make options 1 and 2 into either/or options. I also want to make filters 3-5 mandatory. Is this the correct formula: (1 or 2) and (3 and 4 and 5)?
That is correct, however you don't need the second set of parentheses. You can simply write it: (1 or 2) and 3 and 4 and 5
