# Set up customer segments in Amazon Connect Customer Profiles A *customer segment* is a group of customer profiles that share certain attributes. For example, a customer segment might contain all of your customers who live in a particular city, or all customers who are frequent callers and whose average spend is more than 500 dollars. With Amazon Connect Outbound campaigns, you can send campaigns to a customer segment. Customer segments are dynamically evaluated based on attributes that you define, and can change over time when the value of the attributes change. For example, if you add new profiles to Customer Profiles domain, or if you modify or delete existing profiles, the number of profiles in that customer segment may increase or decrease. For more information about creating a customer segment, see [Build customer segments in Amazon Connect](customer-segments-building-segments.md). As a prerequisite to building segments in Amazon Connect, your administrator must setup your domain in the AWS Management Console and configure integrations to bring profile, order, asset, and/or case data into Customer Profiles. For more information, see [Enable Customer Profiles for your Amazon Connect instance](enable-customer-profiles.md). Enabling data integrations will let continue to generate your dynamic segments based on new data coming to your domain Customer segments only contain customer profiles in your Amazon Connect Customer Profiles domain. Customer Profiles can be ingested from S3 or external applications, or created through Agent App, Contact Flows, or API.
