Blacklist Lookup
Spam blacklists (also called blocklists or RBLs) are databases of domains and IP addresses associated with spam, phishing, or malware. Email providers, security software, and some ad networks use these lists to filter traffic. This tool checks your domain and IP against dozens of major lists simultaneously.
SEO, GEO & AEO: why this checklist matters
Who should use this
Email marketers, system administrators, webmasters who've noticed sudden drops in email deliverability, and site owners after recovering from a malware infection.
Rankings, AI answers, and citations
Google maintains its own Safe Browsing database, separate from most spam blocklists. Being on non-Google blocklists doesn't directly cause Google ranking drops, but being on Google's Safe Browsing list will show security warnings in Chrome and cause significant traffic loss. Check your Google Search Console Security Issues report for Google's assessment.
What to verify before you ship
- Run this check after any malware incident, even after cleanup
- Check both your domain and your sending IP address (they may be on different lists)
- Read the reason for each listing before attempting delisting — fix the cause first
- Re-check after 24-48 hours following a delisting request

Frequently asked questions
Written for search snippets, People Also Ask-style surfaces, and answer engines that quote short Q&A units.
How do I get removed from a blacklist?
Each blacklist has its own delisting process. Most require you to demonstrate the issue is resolved (malware removed, spam stopped) before they'll consider the request. Process time ranges from minutes to weeks depending on the list.
Does a blacklist listing affect Google rankings?
Third-party spam blocklists don't directly affect Google rankings. However, Google's own Safe Browsing database does. If Google flags your site for phishing or malware, Chrome shows a full-page warning before users reach your site.
How do sites end up on blacklists?
Common reasons: sending spam email, hosting malware, phishing pages, SEO spam (comment spam, link spam), or sharing an IP with a site that does these things.
How long does it take for a listing to clear?
Some automated lists clear within 24 hours once the issue is resolved. Others have manual review processes that take days or weeks. Keep documentation of what you fixed and when.
