Multi-blacklist monitoring

Scan your domain and IPs across 50+ major email blacklists simultaneously. Get instant status and delisting instructions.

This scan checks 65+ major blacklists and may take 20-30 seconds to complete

What It Does

Check 50+ major blacklists in one query. Enter your domain or IP and we scan Spamhaus (ZEN/DBL/PBL), SpamCop, SORBS, Barracuda, URIBL, and dozens more.

See which lists you're on (if any), why you were listed, how to request removal, and when listings will auto-expire.

Why It Matters

Being blacklisted destroys deliverability overnight. One spam complaint spree or compromised server and you're added to Spamhaus—suddenly Gmail blocks all your mail.

Most senders don't realize they're blacklisted until campaigns already failed. This scanner catches listings immediately so you can delist before major damage.
