Hi burcakk14301493,
You can use customer attributes to achieve this.
Enterprise customer data collected through multiple sources and stored inside a CRM database can be used in Target to strategically deliver the most relevant content to customers, specifically focusing on returning customers. The People core service (formerly Profiles and Audiences) brings together data collection and analysis with testing and optimization, making data and insights actionable.
Once the data is uploaded, In Target, you can select a customer attribute from the Visitor Profile section when creating an audience. Combine these attributes as required with other data attributes to build audiences.
More information can be found at Customer Attributes
