Getting this wrong now triggers blocks at Gmail and Yahoo. The checklist that keeps you clean.
🛡 Mechanics
— Implement one-click List-Unsubscribe headers — Gmail/Yahoo bulk-sender rules require it; missing it gets you throttled.
— Process unsubs within 2 days, no login wall — the rules mandate it, and friction just drives spam complaints instead.
📥 Design
— Make unsubscribe easier than complaint — a visible link beats the 'report spam' button, which hurts you far more.
— Offer a downgrade option — 'less often' or topic-choice catches people who'd otherwise leave entirely.
📊 Monitor
— Keep complaints under 0.1% — the hard ceiling the big providers enforce.
Why these made the cut: they map directly to the enforced sender requirements, not legacy 'best practice' folklore.
Saved you ~2 hours of compliance reading.
