Domain Got Blacklisted: The Recovery Playbook

Domain Got Blacklisted: The Recovery Playbook
Don't panic-buy a new domain on hour one. Work the list first.

— Step 1: identify which blacklist via MXToolbox. Spamhaus, SORBS, and Barracuda matter most.
— Step 2: stop ALL sending from the domain immediately — more sends deepen the listing.
— Step 3: file delisting requests on each blacklist's portal; some auto-delist in 24-72h.
— Step 4: fix root cause — bad list, no auth, volume spike — or you'll re-list in a week.
— Step 5: re-warm the domain for 7-10 days before resuming real sends.

Pros
— Recovers an aged domain worth more than a fresh one
— Forces you to fix the actual problem
Cons
— Spamhaus delisting can take days with no ETA
— Repeat listings make recovery progressively harder

Verdict: Worth recovering once; burn it if it lists twice. 3.5/5.

Who it's for: Senders who just got the dreaded blacklist alert.
