Email Blacklist Checker

Enter a domain or a sending IP - or paste a whole list of up to 25 in Bulk check - and we’ll query the major IP and domain blacklists live over DNS. Every listing comes with what it actually costs you and the real removal path - not just a red flag.

What this does - and doesn’t - tell you

What’s checked
  • Seven IP blacklists, including Spamhaus ZEN, Barracuda, SpamCop and Mailspike.
  • Three domain blacklists: Spamhaus DBL, SURBL and URIBL.
  • For a domain, the IPs of its mail servers (MX) as well.
Worth knowing
  • Some lists refuse free queries from cloud servers. Those show grey and are never counted as clean.
  • Clean here doesn’t guarantee inbox placement - reputation with Gmail and Microsoft is separate.
  • If you send through a provider, check the sending IP, not just the domain.

Listed, and not sure why? A burned IP or domain is usually a symptom - we find the cause and rebuild the setup.
