Why Monitor Your IP Reputation?
Proactive IP blacklist monitoring is essential for any organization that relies on email delivery and clean network reputation

Ensure your emails reach the inbox. Blacklisted IPs cause emails to bounce or land in spam folders, damaging customer trust and revenue.
Prevent Email Delivery Issues
Catch blacklistings early, not days later. Early detection means you can resolve issues before they impact critical transactional emails.
Early Threat Detection
A sudden blacklisting can indicate a security compromise. Our monitoring acts as an early warning system for potential breaches in your network.

Frequently Asked Questions
Everything you need to know about IP blacklist monitoring
IP blacklist monitoring is a continuous service that checks your IP addresses against hundreds of blacklist databases at regular intervals. Unlike a one-time check, monitoring runs automatically and alerts you immediately when a new blacklisting is detected, so you can take action before it impacts your operations.
Scan frequency depends on your plan. The free plan scans every 24 hours, while paid plans scan every 6 hours. Each scan covers all 300+ blacklist databases simultaneously.
You receive an instant email notification with details about which IP was listed, which blacklist flagged it, and when it was first detected. The alert includes specific remediation steps and direct links to the blacklist provider's delisting page.
Yes. You can monitor subnets of any size, from individual /32 addresses up to /16 blocks. Larger subnets count as multiple monitoring slots based on the number of /24 equivalents they contain. For example, a /23 counts as 2 subnets, a /22 as 4, and so on.
Webhook notifications are available on paid plans. You can configure webhooks to integrate with Slack, Microsoft Teams, PagerDuty, or any custom endpoint that accepts HTTP POST requests with JSON payloads.
Yes, our RESTful API is available on paid plans. The API allows you to programmatically add/remove monitored subnets, retrieve scan results, access historical data, and integrate blacklist monitoring into your existing infrastructure management tools.
A blacklist check is a one-time scan that shows the current status of your IP addresses across blacklist databases. Blacklist monitoring is an ongoing service that automatically performs these checks at regular intervals and notifies you when changes are detected, providing continuous protection.
