Facebook Ads lets you create Custom Audiences. With this audience set, you can target your ads to people who visited your website, used your mobile app, or gave you their email address or phone number. You can also create Lookalike Audiences based on the uploaded Custom Audience, to reach new people who are likely to be interested in your business because they’re similar to your Custom Audience.

Through, you can sync your curated customer data on your warehouse to Facebook Custom Audiences. You can then use the audience data to create Lookalike audiences, ads and campaigns.
