Best of the inbox: the 15-minute deliverability self-audit
Run this monthly before a problem becomes a crisis. The clearest checklists, condensed.

🔍 Auth
— Verify SPF, DKIM, DMARC all pass — and that DMARC aligns, not just passes. One tool, one minute via a check-my-auth service.
— Confirm reverse DNS on your IP — missing PTR records quietly hurt placement.

📊 Reputation
— Check Postmaster Tools + SNDS — domain and IP reputation trend matters more than any single day.
— Scan blocklists — Spamhaus, Barracuda, SORBS in one pass.

📥 Engagement
— Pull last 30-day complaint + bounce rates — over 0.1% complaints or 2% bounces means act now.

Why these picks: it's the exact sequence a deliverability consultant runs, compressed into a coffee break.
