Monitor your domain reputation and IP reputation in real time.

14-day free trial
Centralize all your reputation signals into a single dashboard. Monitor your IP blacklist status, domain blacklist listings, and sender reputation scores across multiple data sources, including Spamhaus, Google Postmaster Tools, Microsoft SNDS, DNS checks, and mailbox provider feedback.
Get a holistic view of your sender reputation with metrics such as Sender Score, blacklist status, bounce and complaint rates, and email authentication health (SPF, DKIM, DMARC). Proactively identify issues before they affect inbox placement.
Don’t wait until your campaigns are blocked. Our monitoring system notifies you in real time of Spamhaus listings, Proofpoint or other blacklists, drops in Google Postmaster Tools or Microsoft SNDS reputation, or declines in Sender Score. Multi-channel notifications (email, Slack, Webhook) let you act before blacklist damage escalates.

Postmastery continuously scans your sending IP addresses and email domains against major IP blacklists and domain blacklists, including Spamhaus, Cloudmark, Trend Micro, URIBL, SURBL, Invaluement, 0Spam, Abusix, Barracuda, Proofpoint, SEM and more. Immediate alerts when you’re listed or delisted help you preserve sender reputation and email deliverability.
Our platform continuously monitors domain reputation and IP reputation, scanning for IP blacklist and domain blacklist listings (including Spamhaus listings) and tracking Sender Score, Google Postmaster Tools and Microsoft SNDS signals. We also check email authentication health — SPF, DKIM & DMARC — plus bounce and complaint trends.
Receive instant multi-channel alerts (email, Slack, Webhook) the moment an IP blacklist or domain blacklist event occurs, a Spamhaus listing is detected, Sender Score falls, Google Postmaster Tools or Microsoft SNDS report issues, or an SPF/DKIM/DMARC failure appears. Early warnings let you isolate risky senders, remediate authentication or sending problems, and protect overall sender reputation and inbox placement before blacklist damage impacts deliverability or revenue.
Stay ahead of reputation issues by monitoring your status with Google Postmaster Tools, Microsoft SNDS, and other mailbox provider feedback systems. Detect IP status changes, domain reputation drops, or authentication failures (SPF, DKIM, DMARC) to protect inbox placement and maintain strong sender reputation.
If you’re hit with a Spamhaus listing, IP blacklist, or domain blacklist, identifying the root cause is critical. Our console shows whether the issue is related to SPF, DKIM & DMARC misconfiguration, high bounce rates, deferrals, complaints, or unsubscribe spikes. With campaign-level and sender-level insights, you’ll have the tools to remediate quickly and prevent future blacklisting.
"Postmastery's Reputation Monitor allows proactive delivery monitoring, instead of troubleshooting afterwards."

When every email matters, businesses trust Postmastery's Reputation Monitor to maximize deliverability.
Detect Problem Senders Before They Impact Shared IP Reputation
One bad sender can damage the sender reputation of many others and lead to IP blacklist or domain blacklist listings. Our platform helps you identify problem senders early — spotting Spamhaus listings, complaint surges, deliverability drops, or failing Sender Scores — so you can quarantine or correct them before the damage spreads across your infrastructure.
