Best of the inbox: watch the lists before they watch you
By the time deliverability visibly drops, you've often been on a blocklist for days. The monitoring resources that catch it early.

🚨 Monitoring
— MXToolbox blacklist check + monitoring — checks your IP/domain against 100+ lists and alerts on changes. Made the cut as the free early-warning baseline.
— Spamhaus lookup + the difference between their SBL/CSS/DBL lists — knowing which list you're on tells you what you did wrong.
— A Postmaster-reputation-trend alert setup — watch the bucket drop before the blocklist hits.

🛠️ Recovery
— Sender-reputation-recovery playbooks — slow re-warm, suppress aggressively, mail only your best openers.

Saved you ~2 hours of reactive scrambling. Set monitoring once so the alert finds you — recovery is far cheaper when you catch it on day one.
