Best of the inbox: open rate is lying to you
Apple Mail Privacy Protection inflated open rates into noise. The resources on which metrics still mean something post-MPP.

📉 Metrics
— A 'death of the open rate' post-MPP analysis — why machine-prefetched opens broke the metric for ~50% of your list. Made the cut for naming the real problem.
— A click-to-open and click-rate reframing guide — clicks are now your cleanest engagement signal; build reporting around them.
— A conversion-and-revenue-per-email framework — the only metric that pays rent for affiliate senders.

🧮 Modeling
— A 'last-click engagement window' approach — segment on clicks and visits, not the polluted open data.

Saved you ~2 hours of trusting a broken number. Rebuild your dashboards around clicks and revenue; treat opens as directional at best.
