How to get started with blacklist monitoring

The ZeroBounce Blacklist Checker 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 includes a blacklist checker that alerts you if your addresses are found listed. Using our blacklist checker, you can quickly verify whether your domain or IP address is flagged and take immediate action to resolve any issues.

Blacklist 1

Decide what you’d like to monitor

ZeroBounce can monitor three types of addresses: a standard domain (example.com), an IPv4 address (255.255.255.255) and an IPv6 address (2001:db8::8a2e:370:7334). We recommend monitoring all three types, as this ensures you have the broadest protection across all potential points of blacklist entry.

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. You can also manually check your domain's blacklist status using our service to ensure your domain remains clear. If you’re found listed, we’ll send you an alert email. We also alert you if you’ve successfully delisted your address.

Blacklist 2
Blacklist 3

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 perform an IP blacklist checkⓘ to see if your domain or IP address is listed. This IP blacklist checkⓘ allows you to identify and address any issues before they cause significant damage to your sender's reputation. Once identified, you can swiftly act to have your domain or IP address delisted and mitigate any potential harm.

Frequently asked questions

Blacklist monitoring is a service that monitors your email domain and IP reputation in real time. Blacklist monitors are looking for signs that your email campaigns are automatically blocked or flagged as spam by internet or email service providers. They achieve this by actively performing a blacklist search to look for your email domain on known email blacklist service lists. If your domain appears on one of these lists, you’ll receive a notification so that you can take action.

Protect your company’s reputation. Stay off email blacklists.
