Real-Time Blacklist Monitoring
Protect Your Email Reputation. Stay Ahead of Deliverability Risks.
Your sender reputation is critical to ensuring your emails reach the inbox. One listing on a major DNS-based blacklist (DNSBL) can severely impact your deliverability and undermine your marketing efforts.
Email Deliverability at Risk: Blacklist appearances can prevent your messages from reaching inboxes, harming campaign performance and brand credibility.
Silent Threats: Many blacklists don't notify you when you've been listed - meaning damage can go unnoticed until it's too late.
Speed Matters: The sooner you're aware of a listing, the faster you can resolve it and minimize impact.
Proactively Safeguard your Sender Reputation
Impressionwise’s Blacklist Monitoring Service empowers you to proactively safeguard your sender reputation. Our platform performs automated checks across more than 230 DNS-based blacklists to monitor the health of your sending IP addresses, domains, and mail server infrastructure. Read More.
Email Blacklists Introduction. Internet service providers (ISPs) collaborate closely with blacklist services to identify trustworthy email senders and those that may pose a risk to public safety and privacy. By monitoring and evaluating email sender behavior, ISPs ensure they protect users from potential threats such as spam, phishing, and other malicious activities.
Blacklist Monitoring Overview. Blacklist monitoring is a proactive service designed to protect your email domain and IP reputation in real time. By continuously scanning established email blacklist databases, the system detects whether your sending domains or IP addresses are being flagged or blocked by ISPs or email providers. If a listing is detected, you’ll receive an immediate alert—enabling swift action to address the issue, restore sender credibility, and maintain optimal email deliverability.
With real-time detection and alerting, you'll be notified immediately if any of your assets appear on a blacklist - enabling you to take swift corrective action and minimize potential damage to your email deliverability.
Select domains and IP’s to monitor
Impressionwise's allows you to monitor multiple types of sending assets critical to your email infrastructure.
You can track the blacklist status of:
Sending Domains (e.g., yourdomain.com)
IPv4 Addresses (e.g., 192.0.2.0)
IPv6 Addresses (e.g., 2001:db8::8a2e:370:7334)
For the most comprehensive protection, we recommend monitoring all applicable assets. This ensures full visibility and proactive threat detection across your entire email ecosystem.

Blacklist Remediation: To remove your email domain or IP address from a blacklist, you must contact the blacklist provider directly. Most providers offer online tools to check the status of your domain or IP and identify the reason for the listing. Once the root cause is determined, take the appropriate corrective actions and follow the provider’s removal process to restore your reputation.
Blacklist Listing Removal: After resolving the underlying issue, you may submit supporting evidence to the blacklist provider to request removal. However, repeated violations or multiple blacklist listings can complicate the delisting process. If your sender reputation has been significantly impacted, demonstrating a consistent improvement in your email-sending practices is often required before reinstatement is considered.
