Email Blacklist Checker
Check if your domain or IP address is listed on email blacklists and DNSBL providers
What We Check
Our blacklist checker queries major DNSBL providers to give you a comprehensive view of your email reputation and deliverability status.
Spam Lists
Check against major spam blacklists like Spamhaus, Barracuda, and SORBS that block known spam sources.
Malware Lists
Verify your IP isn't associated with malware distribution, botnets, or compromised systems.
Policy Lists
Check policy-based blacklists that block IPs violating email sending best practices.
Phishing Lists
Detect if your domain appears on phishing and fraud databases used by security providers.
Open Relay Lists
Check for misconfigured mail servers that could be exploited for spam relay attacks.
Dynamic IP Lists
Verify if your IP is flagged as a dynamic/residential IP that shouldn't send email directly.
What To Do If You're Blacklisted
- 1 Identify the Root Cause
Investigate spam complaints, compromised accounts, malware infections, or misconfigured email servers.
- 2 Fix the Underlying Issue
Resolve all problems before requesting delisting. Most providers won't delist until issues are resolved.
- 3 Request Delisting
Follow each blacklist provider's specific delisting process. Use the links in your check results.
- 4 Monitor Regularly
Set up automated monitoring to catch future listings immediately and maintain clean status.
