Cross-channel analytics template for Klaviyo, Shopify, and Facebook Ads that unifies email, e‑commerce, and paid social performance in one view. Track engagement metrics like opens, clicks, bounces, spam complaints, and subscriber growth or churn to spot what triggers unsubscribes. Measure Shopify funnel health—from checkout starts to fulfilled orders—and connect Facebook lead quality to downstream conversions. Compare campaigns across platforms to identify underperformers, prioritize fixes, and optimize budgets. Ideal for marketers who need client-ready KPIs, campaign analysis, and email rate trends without stitching data together.
