Is Your Domain's Reputation Silently Sabotaging You?
A blacklisted domain or IP address is a silent killer of online presence. It blocks your emails from reaching inboxes, triggers security warnings for your website visitors, and can even cause search engines to distrust your site—all without any direct notification to you. Your SEO and communication channels fail before they even begin.
Instantly Diagnose Your Reputation with Our Free Blacklist Check Tool.
Take the guesswork out of deliverability and trust. Our tool performs a comprehensive, real-time check against over 100 of the world's most important spam and security databases. Within seconds, you'll see if your domain or server IP is flagged, where it's listed, and get direct links to resolve the issue.
Why Blacklist Monitoring is Critical for Business Health:
Rescue Your Email Deliverability: If your IP is on a spam list, your marketing campaigns, transactional emails, and even one-to-one messages will land in spam folders or be blocked entirely, destroying communication and revenue.
Protect Your Website's SEO & Trust: Some security blacklists feed directly into browser warnings and search engine evaluations. A listing can lead to reduced visibility and user warnings that shatter credibility.
Identify Hidden Server Issues: A blacklisting is often a symptom of a larger problem—a compromised website sending spam, misconfigured mail server, or a malicious neighbor on a shared hosting IP.
Safeguard Your Brand Reputation: Proactive monitoring prevents your brand from becoming associated with spam or security threats in the eyes of ISPs, email providers, and security services.
From Detection to Resolution in One Workflow.
Our tool provides a clear, actionable report, not just a red flag:
Multi-List Check: Simultaneous query of key databases like Spamhaus, SURBL, Barracuda, and Google Safe Browsing.
Specific List Identification: See exactly which blacklist (e.g., Spamhaus SBL, UCEPROTECT) contains your IP/domain.
Status & Severity: Understand the nature of the listing (e.g., spam, malware, phishing).
Direct Resolution Links: Get direct links to the listing authority's removal process wherever possible.
Your Protocol for Reputation Recovery:
Run the Check: Enter your domain name or server IP address.
Analyze the Report: If clean, maintain good practices. If listed, note every database where you appear.
Diagnose the Root Cause: Fix the underlying issue: clean malware, secure your email server, stop unauthorized mailing.
Request Delisting: Follow each blacklist's official removal procedure using the provided links. Delisting can take from a few hours to several days.
Verify & Monitor: Re-run the check to confirm delisting and schedule regular scans to prevent recurrence.
