How Do I Check My IP Reputation? - TheEmailToolbox.com
Key Features to Consider in IP Reputation Monitoring Tools
Choosing the right IP reputation monitoring tool can make all the difference between catching problems early or scrambling to fix them after they’ve already hurt your email deliverability. These tools are designed to help you stay one step ahead, ensuring your IP reputation remains intact.
One of the most essential features is spam complaint tracking. This monitors how often recipients mark your emails as spam and alerts you when complaint rates exceed thresholds like 0.1%. For example, tools like GlockApps send automatic notifications when this limit is crossed, giving you the chance to adjust your email strategy before your deliverability takes a hit.
Another critical feature is blacklist monitoring. The best tools constantly scan your IP against hundreds of DNS blocklists and platforms like Google Safe Browsing. GlockApps, for instance, checks over 50 blocklists, while others cover more than 100. This wide-ranging coverage ensures you’re immediately notified if your IP gets flagged, allowing you to take action quickly.
Deliverability data analysis goes beyond basic delivery stats. Advanced tools break down where your emails land - whether that’s the inbox, spam folder, or elsewhere - and provide metrics like sender scores. This kind of insight helps you spot trends and address potential issues before they snowball.
Real-time alerts are another must-have. These notifications let you respond instantly to any threats to your reputation, making it easier to resolve problems before they escalate.
With email-based threats on the rise, DMARC compliance tools have become increasingly important. These tools help you set up, analyze, and verify DMARC compliance, which is crucial for protecting your reputation and safeguarding your recipients. Considering that 94% of malware is delivered via email and phishing accounts for 80% of security incidents, monitoring authentication protocols like DMARC is no longer optional.
What sets professional-grade tools apart is their ability to provide comprehensive reporting with actionable recommendations. Instead of just dumping raw data on you, these platforms explain what’s wrong and offer specific steps to fix the issues. For instance, BarracudaCentral not only flags risky IPs but also provides detailed risk-level explanations, helping you understand how your IP is perceived.
Here’s a quick comparison of these key features:
For the best results, look for tools that integrate seamlessly with your email systems. This ensures constant monitoring and enables automated responses to reputation changes. Unified dashboards that consolidate all these features in one place are especially helpful, giving you a complete view of your email health and reputation status without needing to juggle multiple tools.
ManageEngine OpUtils combines IP reputation management with comprehensive network monitoring, bringing these functions together in a single, user-friendly dashboard. This integration provides IT administrators with a clear and unified view of both network health and IP reputation, streamlining infrastructure oversight.
The platform functions as a versatile network management tool. Pricing starts at $595 per year for up to 500 IP addresses. OpUtils offers a free edition with basic features and a Professional Edition for advanced monitoring capabilities. Let’s dive into how its features support effective IP reputation management.
Blacklist Monitoring
OpUtils helps safeguard your organization’s email deliverability by offering robust blacklist monitoring. It continuously checks your IP addresses against major DNS-based blacklists (DNSBLs) and Real-time Blackhole Lists (RBLs), alerting you immediately if any of your IPs are flagged.
This feature is critical in today’s landscape, where email-based threats are widespread. If an IP gets blacklisted, it can disrupt email campaigns and cause legitimate messages to be marked as spam, which could significantly impact daily operations.
The platform scans your organization’s outbound email IP addresses across multiple blacklist databases. If an issue is detected, OpUtils flags it right away, enabling your IT team to act quickly and minimize any negative effects on email deliverability. This proactive approach is essential for maintaining a strong sender reputation and ensuring your email communications remain effective.
Real-time Alerts
OpUtils offers real-time notifications to keep you informed about IP reputation issues as they arise. Alerts are sent via email or displayed on the dashboard whenever blacklisted IPs or suspicious activity are detected. Many organizations have reported improved visibility and faster response times to reputation-related incidents after adopting OpUtils. These immediate alerts allow your team to address potential threats promptly, supporting a broader strategy to protect your sender reputation.
Deliverability Insights
While OpUtils doesn’t provide detailed email analytics, it plays a key role in maintaining email deliverability through its network-focused monitoring. Its blacklist monitoring feature acts as an early warning system, helping prevent emails from being blocked or marked as spam. However, the platform does not include specific email metrics like inbox placement rates or spam complaint statistics.
What sets OpUtils apart is its ability to consolidate various network health metrics, including blacklist status, into a single dashboard. This integrated view helps IT teams quickly correlate blacklist events with other network issues, speeding up root cause analysis and resolution.
For organizations in the U.S., OpUtils aligns with data privacy regulations by operating entirely within the internal network. This ensures sensitive IP and network data remain under local control while providing detailed audit trails for monitoring activities. This comprehensive monitoring approach allows IT teams to efficiently tackle network issues that could impact email deliverability.
BarracudaCentral evaluates IP addresses by analyzing their sending history to determine whether they're trustworthy or problematic for email delivery. What makes it stand out is its integration with the Spam and Virus Firewall, which uses sender IP reputation to either block or allow emails. While the platform offers free reputation lookups, advanced features and integration with Barracuda appliances may require a subscription or additional hardware/software purchases. These capabilities make it a go-to tool for managing email reputation effectively.
Blacklist Monitoring
A key feature of BarracudaCentral is its real-time blacklist, known as the Barracuda Reputation Block List (BRBL). This list flags IP addresses linked to spam or harmful activity, which can lead to emails from those IPs being blocked or filtered as spam, affecting email deliverability. The tool checks both proprietary and public blocklists and supports manual lookups as well as API-based automated monitoring. With real-time updates to its database, organizations can quickly identify and address spam or malicious behavior. The system also evaluates URLs embedded in emails, offering a comprehensive assessment of the sender's overall trustworthiness.
Real-time Alerts
Although BarracudaCentral doesn’t include built-in real-time alerts, its API allows third-party tools to provide notifications for any changes. Organizations can use the API to create custom monitoring solutions that regularly check their reputation status. This flexibility enables IT teams to develop tailored alert systems for staying on top of reputation changes.
Deliverability Insights
BarracudaCentral offers straightforward deliverability insights by categorizing IPs as either "good" or "bad", based on factors like spam reports and sending patterns. While it doesn’t provide in-depth analytics, such as inbox placement rates, its reputation classifications give a solid indication of potential deliverability problems. If an IP is flagged as "bad", businesses should investigate possible causes, such as spam complaints, compromised accounts, or outdated mailing lists. To address these issues, recommended steps include cleaning mailing lists, enhancing email content, securing mail servers, and submitting a delisting request through BarracudaCentral’s online form after resolving the underlying problems.
3. MxToolbox
MxToolbox is a diagnostic tool designed to keep your email operations running smoothly by monitoring IP reputation and email health. It offers both free, on-demand checks and paid, automated monitoring services. With its broad blacklist coverage and actionable recommendations, it helps businesses safeguard their sender reputations.
Blacklist Monitoring
MxToolbox's SuperTool scans your IP address against more than 100 blocklists, including well-known databases like Spamhaus and Barracuda. While the free version covers the top 30 blacklists, paid plans unlock access to all available databases and allow monitoring of multiple domains. The platform provides detailed results, including links to delisting procedures, so you can quickly address any flagged issues. This ensures you’re equipped to take immediate and informed action.
Real-time Alerts
For those who want to stay ahead of potential problems, MxToolbox offers real-time notifications as part of its paid plans. If your IP or domain gets blacklisted or its reputation changes, you'll receive instant alerts. This feature eliminates the need for constant manual checks and allows businesses to resolve deliverability issues quickly and efficiently.
Deliverability Insights
Beyond blacklist monitoring, MxToolbox dives deeper into the health of your email infrastructure. It evaluates mail server configurations, DNS settings, and overall domain health. Paid plans come with advanced features like inbox placement analysis, delivery performance tracking, and complaint reporting. Additionally, the platform includes SPF and DKIM checks to guard against domain spoofing and phishing attempts. These tools not only protect your IP reputation but also help ensure your emails consistently reach inboxes.
For U.S.-based businesses, MxToolbox is particularly aligned with local deliverability standards and tracks major American blocklist providers. Its diagnostic tools are a valuable asset for IT teams and email administrators who need to maintain reliable email performance and protect their sender reputation.
4. GlockApps
GlockApps stands out with its well-rounded approach to email reputation management. It doesn’t just stop at checking blacklists; instead, it dives deeper by monitoring both domain and IP reputation while offering detailed insights into email deliverability. The platform scans over 50 industry blocklists, ensuring potential issues are caught early and addressed promptly.
Spam Complaint Monitoring
A standout feature of GlockApps is its real-time tracking of spam complaints. The platform keeps a close eye on complaint rates across your email campaigns and sends immediate alerts if complaints exceed the critical 0.1% threshold. Along with these alerts, GlockApps provides actionable recommendations to help you address the issue. These suggestions may include tweaking your email content, refining your audience targeting, or improving list hygiene practices.
Blacklist Monitoring
GlockApps provides clear, detailed reports that show exactly which blocklists - if any - have flagged your domain or IP. It also offers specific steps to help you resolve these issues effectively.
Alex Arnaut, CEO at GlockApps, highlights that their tools are designed to help users maintain strong email deliverability and protect sender reputation through comprehensive monitoring, actionable insights, and compliance tools.
The platform’s real-time monitoring ensures you’re alerted to blacklist issues within minutes, so you can address problems before they impact your campaigns.
Deliverability Insights
GlockApps goes beyond basic blacklist checks by offering in-depth deliverability insights.

Blacklist Monitoring
Everest continuously scans sender IPs and domains against major blocklists, providing instant alerts and actionable steps for remediation. This proactive approach helps businesses quickly resolve blacklist issues, minimizing any negative impact on campaign performance.
Real-time Alerts
One of Everest's standout features is its real-time alert system.

These alerts enable businesses to respond swiftly, preventing long-term damage to their sender reputation. For example, a U.S.-based e-commerce company used Everest’s alerts to identify and resolve a blacklisting issue, restoring their email deliverability within days. This kind of responsiveness makes Everest an essential tool for enterprises looking to optimize their email performance.

Cisco Talos Intelligence is a free online tool that taps into Cisco's extensive global security network, analyzing billions of data points every day to provide real-time IP reputation assessments. Using a straightforward traffic light system, it categorizes sender reputations as good, neutral, or poor. It also includes spam-level ratings, ranging from low to high, giving users a quick snapshot of potential email deliverability concerns.
Blacklist Monitoring
One of Talos's standout features is its ability to monitor blacklists effectively. It continuously scans IP addresses against major blocklists, making it easy to check if an IP is flagged. If an IP address is listed, Talos provides details about the issue, such as connections to spam, malware, or phishing activities. The system updates frequently, ensuring the information reflects the latest threat intelligence and reputation changes.

Deliverability Insights
Talos simplifies deliverability tracking with its reputation scoring system. It not only shows the reputation of your IP but also compares it to other server IPs, helping you identify any risks that could harm your email campaigns. The spam-level ratings further assist in assessing whether your emails are likely to land in inboxes or be flagged as spam. While it doesn’t offer detailed analytics, the threat intelligence it provides can offer a broader understanding of security risks.
Real-time Alerts
Although Talos doesn’t send direct alerts to individual users, it keeps organizations informed by publishing real-time updates on spam and malware threats. An interactive map highlights the origins of these threats, giving a visual overview of emerging risks. Many organizations pair Talos with automated alert systems to ensure comprehensive monitoring of their IP reputation and security status.
7. Sender Score by Validity
Sender Score by Validity is a widely used tool that rates your IP on a scale of 0–100, providing insight into your email deliverability. It uses a rolling 30-day average to evaluate your sending performance, making it easier to track changes in reputation over time.
The score is recalculated daily, offering near real-time updates about your sender reputation. According to industry data, senders with scores above 80 can achieve inbox placement rates of up to 95%, while scores below 60 often result in rates dropping to around 70%. This strong link between Sender Score and deliverability highlights its importance for email marketers and IT teams. Let’s dive into how Sender Score tackles spam complaints, deliverability challenges, and more.
Spam Complaint Monitoring
Spam complaints are a critical factor in Sender Score’s calculation. The tool tracks how often recipients mark your emails as spam, providing insight into potential issues with your campaigns. If complaint rates rise, your score will drop, acting as an early warning that your reputation is at risk. While it doesn’t offer detailed complaint data, fluctuations in your score can point to trends, helping you adjust your approach before problems escalate.
Deliverability Insights
Sender Score also provides key deliverability insights by analyzing metrics like bounce rates, spam trap hits, and complaint rates. These indicators help identify potential problems that could harm your campaigns. For example, organizations that raise their scores from below 70 to above 80 often experience noticeable improvements in inbox placement and campaign ROI. The tool’s straightforward scoring system makes it accessible for users of all technical skill levels, simplifying the often complex world of deliverability monitoring.
Blacklist Monitoring
A sudden drop in your Sender Score might signal that your IP has been blacklisted. Being listed on major blacklists can significantly hurt deliverability. While Sender Score doesn’t directly monitor blacklists, it acts as an indirect warning system. A dip in your score could indicate that it’s time to check for blacklist issues.
To fully address blacklist monitoring, many organizations combine Sender Score with specialized tools. This dual approach helps catch both gradual reputation declines and unexpected blacklist events, ensuring email delivery remains consistent.
Real-time Alerts
Although Sender Score doesn’t offer built-in real-time alerts, it can be paired with other Validity products or third-party tools that provide instant notifications. These integrations allow you to respond quickly to score drops or other reputation issues before they impact your deliverability.
For manual monitoring, the free online lookup feature is available. For more advanced capabilities, Validity’s paid Everest platform includes enhanced alerting options. This tiered system lets businesses choose monitoring solutions that align with their email volume and risk management needs.
Regularly checking your Sender Score is essential for maintaining a strong sender reputation and high inbox placement rates. Experts suggest reviewing your score weekly and addressing any negative trends immediately. This could involve improving list hygiene, reducing complaint rates, or revisiting your sending practices. Staying proactive can help you avoid long-term deliverability issues and maintain trust with major email providers.

All pricing is listed in US dollars, with flexible billing options available. As the industry leans more toward automated, real-time monitoring, these tools are evolving to meet growing demands.
How Artemis Leads Manages IP Reputation
At Artemis Leads, maintaining a spotless IP reputation is at the heart of every successful B2B outbound campaign. With email threats costing organizations a staggering $17,700 per minute, ensuring smooth deliverability is non-negotiable.
To stay ahead, Artemis Leads employs a multi-tool strategy, combining platforms like MxToolbox, BarracudaCentral, and Cisco Talos Intelligence. These tools provide essential services such as continuous blacklist monitoring, sender reputation analysis, and advanced threat detection. Unlike agencies that rely on a single tool, Artemis Leads’ approach offers broader coverage, catching issues before they escalate into deliverability problems.
Real-time alerts are central to their process, monitoring sender scores, blacklist statuses, and spam complaints (flagged at just 0.1%). This proactive system ensures immediate action if any red flags arise.
Authentication protocols are another cornerstone of Artemis Leads’ strategy. By auditing and fine-tuning DMARC, SPF, and DKIM records, they achieve an impressive 90-100% DMARC compliance rate using tools like GlockApps. This rigorous setup significantly reduces the risk of spoofing attacks, which can severely harm sender reputation.
But Artemis Leads doesn’t stop at technical measures. They enhance their campaigns with personalized outreach, using real team member names and matching accounts to establish a consistent sender identity. This personal touch helps reduce spam complaints and builds trust with recipients.
When issues do arise, Artemis Leads acts fast. Their team dives deep into the root cause using detailed reports from monitoring tools, adjusts sending patterns, updates authentication records, and submits delisting requests to blacklist operators. This swift action minimizes disruptions and keeps campaigns on track.
They also analyze inbox placement to optimize visibility. This data-driven fine-tuning directly improves lead engagement and conversion rates. For instance, during a recent campaign, a sudden drop in inbox placement was flagged by their monitoring tools. The team quickly identified and corrected an authentication misconfiguration by updating SPF and DKIM records and submitting delisting requests. As a result, inbox rates rebounded to over 95%, underlining the importance of proactive monitoring and rapid remediation.
To ensure ongoing success, Artemis Leads conducts weekly reviews of sender scores, blacklist statuses, spam complaints, and inbox placement. These regular assessments help identify trends and make adjustments before they can impact performance. This consistent vigilance is key to their ability to deliver results.
Conclusion
Keeping an eye on your IP reputation isn't just a technical task - it's a critical move that directly impacts your business's success. With email marketing in the U.S. generating an average return of $36 for every $1 spent, maintaining high deliverability rates is essential for effective outreach.
Here’s the reality: senders with strong reputations enjoy inbox placement rates above 95%, while those with weaker reputations can see rates plummet below 50%. For B2B companies relying heavily on email, that gap represents thousands of missed opportunities and a significant loss in revenue. This highlights the need for a monitoring strategy tailored to your organization’s unique needs.
When choosing tools, consider the size and scale of your business. Smaller businesses can start with free or budget-friendly options like MxToolbox or BarracudaCentral, which handle basic blacklist monitoring. If you’re running larger, high-volume email campaigns, advanced solutions like Validity Everest or GlockApps provide in-depth analytics and real-time alerts to optimize performance.
Key features to prioritize include real-time blacklist monitoring, tracking spam complaints (especially if they hit 0.1% or higher), deliverability analytics, and seamless integration with your current email platforms. For U.S. businesses, make sure the tools you choose align with local compliance standards and offer reports in familiar formats.
It’s also worth noting that 94% of malware is delivered via email, making IP reputation management about more than just deliverability - it’s about safeguarding your organization as a whole. Whether you’re a startup launching your first campaigns or a large enterprise juggling complex strategies, the right monitoring tools ensure your emails land where they’re meant to and protect your brand’s credibility.
The real question isn’t whether you can afford to invest in IP reputation monitoring - it’s whether you can afford not to.
