Blacklist monitoring
Checks a domain against major blacklists to surface whether it may be associated with spam or malicious activity.
Truelist
Truelist’s Domain Reputation Checker is a free web tool for assessing blacklist status, email authentication, infrastructure, and overall domain health. It returns a reputation score and recommendations to help with email deliverability and trust.
What it is
Truelist’s Domain Reputation Checker is a free web tool for assessing how a domain is likely to be viewed by email providers and other trust systems. It examines blacklist status, email authentication, infrastructure signals, and general domain health, then summarizes the result as a reputation score with recommendations.
The checker is part of the Truelist email validation platform. The site positions Truelist around email verification, bulk list cleaning, real-time API verification, enhanced reporting, and deliverability monitoring, so this tool fits into a wider workflow for maintaining sender reputation and reducing deliverability problems.
Core capabilities
Authentication analysis
Reviews email authentication setup, including SPF and DMARC, to identify configuration issues that can affect trust and deliverability.
Infrastructure review
Inspects infrastructure signals such as MX records and DNS-related setup to help assess whether a domain looks legitimate and operational.
Reputation scoring and guidance
Generates an overall reputation score and pairs it with recommendations instead of leaving users with only raw status checks.
Broader email operations context
Connects domain reputation to the broader email validation platform, which also includes API access, bulk list verification, reporting, and deliverability monitoring.
Common ways to use it
Pre-campaign deliverability review
Check a sending domain before launching outreach or newsletter campaigns to see whether blacklist status or authentication issues may hurt deliverability.
DNS and email setup validation
Audit SPF, DMARC, MX, and related setup after DNS changes or a new domain purchase to make sure the domain is configured for email use.
Troubleshooting reputation issues
Investigate a sudden drop in inbox placement or a reputation problem by reviewing the same signals providers use to judge domain trust.
Part of an email operations workflow
Use the checker alongside Truelist’s broader validation tools when cleaning lists, validating signups, or maintaining sender reputation over time.
