Ktorá z možností je príkladom vlastných zoznamov zákazníkov, ktoré podporujú prispôsobené kampane s vysokou výkonnosťou?

The correct answer focuses on leveraging existing customer data to identify and re-engage loyal customers with personalized offers. This strategy directly supports customized campaigns with high performance because loyal customers are more likely to convert, and personalized offers increase relevance and effectiveness. The other options are less effective or problematic. "Reaching users who have not shown interest... and do not want to be targeted" is inefficient and violates privacy expectations. "Reaching online and offline users... maximizing uploaded third-party data" can be effective but carries higher privacy risks and data quality concerns compared to first-party data. "Reaching users who have not yet interacted with your site... to expand audience size" is a valid strategy for audience expansion but typically has lower conversion rates than targeting loyal customers, thus not maximizing "high performance" in the same way.
