Usecase: We’re an event/conference company focused on the alternative investment industry. We’d like to start running meta ads to promote our events. We have a large database of potential customers in our industry, 50,000+. The data is centered around work emails. When we upload our customer list to meta it doesn’t event identify 1000 people. We think this is because most people use their personal email address for meta instead of their work email. Out thinking is that enriching our customer list with MAID’s would help meta construct our audience better.
