How to Create Custom Audience Using Email List in Facebook Ads?

In this article, we are going to learn how to create a custom audience in Facebook Ads Manager using an email list. This method is very useful for businesses that already have email IDs of their existing customers or prospective customers.

If you are running a business and you have collected email IDs through sign-ups, inquiries, or past customers, you can use those email IDs to show your ads directly to those users on Facebook and Instagram. These users have already interacted with your business in some way, which makes them a valuable audience for retargeting.

This article explains the complete step-by-step process of creating a custom audience using a customer email list in Facebook Ads Manager.

An email list custom audience allows you to upload email IDs of users you already have and match them with Facebook or Instagram accounts created using those same email IDs.
