The colleague tells Antonio that he doesn't need to exclude people from his original re marketing lists when setting up a similar audiences list because**similar audiences lists automatically exclude people so that only new leads are reached**. The primary goal of similar audiences is to find new users who share characteristics with those on your re marketing lists, ensuring that you're reaching new potential customers who have a high likelihood of being interested in your product or service.
