Email Blacklist Checker
Check if an email address's domain is listed on major blacklists. This helps you understand if emails from this address might have deliverability issues.
About Email Blacklist Checking
When checking an email address, we look up the domain portion (after the @) against major domain blacklists. If the domain is blacklisted, emails sent from any address at that domain may be blocked or sent to spam.
What We Check
- Email domain against major domain blacklists (DBLs)
- MX records to identify mail servers
- Multiple RBL sources for comprehensive coverage
Note: This checks the domain reputation, not the individual email address. Individual email addresses cannot be directly checked against most blacklists.
