Best of the inbox: the metric you're ignoring

Best of the inbox: the metric you're ignoring
Framing: open rate is vanity; complaint rate is the number that gets you blocked. Above 0.3% and Gmail acts. Picks that retrain your dashboard:

🚀 Deliverability
— The 0.1% complaint ceiling guide — earned its spot for the hard threshold and how feedback loops feed it.
— List-Unsubscribe header setup — picked because a one-click unsub diverts complaints that would otherwise hit "spam."

🧪 Tests
— Visible-unsub vs. buried-unsub data — worth it: easier unsubs lowered complaints AND raised list health.

📥 Swipe
— The frequency-preference center copy — included as the complaint pressure-release valve.

Through-line: make leaving easy so they don't report you.
Saved you ~75 minutes of staring at the wrong KPI.
