How to get started with blacklist monitoring

The ZeroBounce Blacklist Monitoring service will provide invaluable information about your domain, IP address and mail server blacklist status. Our system delivers automated checks of over 200 blacklist providers, and will alert you if yours are found listed.

Decide what you’d like to monitor

ZeroBounce can monitor three types of addresses: a standard domain (, an IPv4 address ( and an IPv6 address (2001:db8::8a2e:370:7334). We recommend monitoring all three types, as this will provide greater coverage.

Get notified if you’re found on any blacklists

Once your monitors are active, you’ll be notified if your addresses are found on any blacklists. We actively monitor over 200 blacklist providers. Depending on the subscription-level you’ve chosen, our automated checks will happen over multiple intervals, daily. And if you’re found listed, we’ll send you an alert email. We also alert you if you’ve successfully delisted your address.

Act quickly & prevent sender reputation damage

Our email alert system will also provide you with the contact link to each blacklist provider’s website. From there you can quickly act to have your domain or IP address delisted and mitigate any damage your sender reputation may experience.
