Ehsan's Analysis
Email open rates in SaaS are overreported by 20-30% due to Apple Mail Privacy Protection (MPP), which pre-loads tracking pixels for all emails on iOS/macOS Mail clients. Since Apple Mail represents 50-60% of email clients, your "45% open rate" might be 30% in reality. The metric that survived MPP: click-to-open rate (CTOR) — clicks divided by opens. CTOR is not inflated by MPP because fake opens do not generate fake clicks. SaaS email benchmarks post-MPP: product update emails should target 3-5% CTOR, onboarding sequences 8-12% CTOR, usage-triggered emails 15-25% CTOR. The highest-performing SaaS emails are triggered by user behavior (trial expiring, feature unused, usage milestone), not sent on a schedule. Intercom data shows behavioral emails generate 4x higher CTOR than broadcast emails. Stop measuring open rates entirely — they are fiction. Measure CTOR and revenue-per-email instead.
