IP Blacklist Check

What is an IP Blacklist?

An IP blacklist (also called DNSBL or RBL - DNS-based Blackhole List) is a database of IP addresses known to send spam or malicious content. Email servers and spam filters check these lists to block unwanted mail.

If your IP is blacklisted, your emails may be rejected or sent to spam folders. This tool checks your IP against 15+ major blacklists to help you identify and resolve deliverability issues.

Why Might My IP Be Blacklisted?

• 1Malware or Virus: Your computer may be infected and sending spam without your knowledge.
• 2Shared IP: If you're on a shared hosting or VPN, another user may have caused the listing.
• 3Compromised Email: Your email account may have been hacked and used to send spam.
• 4Dynamic IP: Your ISP may have assigned you an IP previously used by a spammer.
