Email Open Rate & CTR (Apple MPP Reality)
Why Apple Mail Privacy Protection (MPP) inflates open rates and makes Click-to-Open Rate (CTOR) the true metric
In Simple Words (Zero Jargon):
How Apple iPhones auto-open emails in the background (faking 60%+ open rates), making click-through rate the only honest measure of real engagement.
Official Mathematical Equation
CTOR% = (Unique Clicks ÷ Unique Opens) × 100 | Click Rate% = (Unique Clicks ÷ Delivered Emails) × 100
What You Get: Accurate engagement evaluation that isn’t fooled by artificial Apple Mail privacy auto-opens.
