Email Metrics Report

I have a requirement for custom reporting in Oracle Eloqua. We recently executed a broad-reach email campaign, but I need to extract performance KPIs—specifically opens and clicks—filtered for a subset of approximately 6,000 specific domains. Since the original audience was much larger, I need to isolate the metrics for only this specific list provided by our team. What is the most efficient way to pull email KPIs filtered by this domain list in Eloqua Insight?"
