You think you're under the 0.30% spam ceiling. Google's actual bar is 0.10% — 0.30% is the rejection cliff, not the pass mark. Audits SPF/DKIM/DMARC alignment, one-click unsubscribe, and complaint rate, and won't hand a sub-5,000/day sender a false all-clear.

**This is a preview.** The full skill (method, Iron Rules, dated snapshots, worked examples) is available on Agensi:
