Email Blacklist Check - Is My Email or domain Blacklisted?

An email blacklist (or blocklist) is a database of IP addresses and domains that have been identified as sources of spam or malicious email. When your IP or domain is on a blacklist, your emails are more likely to be blocked or sent to spam folders by email servers that use these lists.

Use our free blacklist checker tool to instantly check your domain, IP address, or email against 8 major blacklist databases including Spamhaus, SORBS, SpamCop, and Barracuda. Simply enter your information and get immediate results showing which blacklists (if any) have flagged you.

Common reasons for IP blacklisting include: sending spam or unsolicited emails, compromised email accounts sending spam without your knowledge, high bounce rates from invalid email addresses, receiving spam complaints from recipients, being on a shared IP with other spammers, or having malware on your server sending emails.

Removal time varies by blacklist. Some automatic listings expire after 24-48 hours if no new spam is detected. Others require manual delisting requests which can take 1-7 days. Spamhaus typically processes removals within hours if issues are resolved, while SORBS may take several days. Always fix the underlying problem before requesting removal.

No, different email providers use different combinations of blacklists. Gmail, Outlook, and Yahoo each have their own internal systems plus they may reference public blacklists like Spamhaus. That's why it's important to check multiple blacklists and maintain good sending practices across all of them.
