When you try to send an important business email and it gets rejected by the server or lands directly in the recipient's junk folder, your IP address or domain may have been placed on a Real-time Blackhole List (RBL). Our tool instantly queries the world's most prominent anti-spam databases to help you identify reputation issues so you can restore your email deliverability.
Blacklists are an automated defense mechanism used by email providers like Microsoft, Google, and Apple to protect users from spam and malware. Your server might be blacklisted if a device on your network was compromised by a virus, if your website was hacked to send out bulk spam, or even if you simply inherited a "dirty" IP address from your local internet service provider. Identifying where you are listed is the first step to clearing your name.
Getting listed on a major database like Spamhaus or Barracuda can bring a company's communication to a grinding halt. Once our tool identifies which RBL has flagged your domain, you can begin the remediation process. This usually involves securing your network, setting up proper SPF and DMARC records, and submitting a formal delisting request to the blacklist provider.
We query the most influential and widely-used anti-spam lists globally, ensuring that if you are blocked anywhere, our tool will find it immediately.
You can scan both your website's domain name (e.g., yourbusiness.co.uk) or your direct IPv4 address to get a comprehensive view of your digital reputation.
Your lookup queries are completely private. We don't store your IP logs or sell your search data. Check your network health securely and anonymously.
Removing your IP from a global blacklist can be complicated. Our email deliverability and IT experts can identify the root cause of your listing, secure your network, and manage the delisting appeals for you.
