Email Security Analyzer
This Email Security Analyzer scans your domain’s SPF, DMARC, DKIM readiness, and blacklist status in real time. It generates a security score, grade, and actionable recommendations to help improve email authentication and deliverability.
About This Tool
The Email Security Analyzer evaluates your domain’s overall email authentication posture by checking SPF configuration, DMARC enforcement, DKIM readiness, and blacklist reputation.
Email authentication failures can cause messages to be marked as spam, rejected by recipient servers, or exploited in phishing attacks. This tool provides a unified security score and grade to identify weaknesses quickly.
You can use this tool to:
- Verify SPF record presence and enforcement strength
- Analyze DMARC policy configuration and alignment
- Check server IP blacklist reputation
- Identify authentication misconfigurations
- Improve email deliverability and sender trust
The analyzer performs real-time DNS queries and blacklist checks without storing or logging any domain information. It provides a transparent score breakdown and actionable recommendations.

Frequently Asked Question
What does the Email Security Analyzer check?
The Email Security Analyzer evaluates your domain’s email authentication configuration by checking SPF record presence and enforcement strength, DMARC policy configuration, and server IP blacklist reputation. It generates a security score and grade based on these factors to help identify weaknesses that may affect email deliverability and domain trust.
What is a good email security score?
A score between 80 and 100 indicates strong email authentication configuration and low spam risk. A score between 60 and 79 suggests moderate configuration with areas for improvement. A score below 60 may indicate weak authentication policies or blacklist risks that could impact inbox placement and sender reputation.
Why does SPF show “Not Found on Root Domain”?
Some domains publish SPF records on dedicated sending subdomains instead of the root domain. In such cases, the analyzer may not detect SPF on the main domain even though email authentication is configured elsewhere. It is recommended to verify the exact domain used for sending emails.
Why does DMARC show “Not Found”?
If no DMARC record exists under the required _dmarc.yourdomain.com hostname, the tool will display it as not found. Without DMARC enforcement, a domain is more vulnerable to spoofing and phishing attacks. Implementing a proper DMARC policy improves email security and brand protection.
Does this tool check DKIM automatically?
DKIM uses unique selectors that vary depending on the email provider. Since selectors differ between domains and services, automatic detection may not always be possible. Manual selector verification is often required for complete DKIM validation.
What happens if my domain is blacklisted?
If your server IP address appears on a DNS-based blacklist, emails may bounce, be rejected by recipient servers, or land in spam folders. Blacklisting can occur due to spam complaints, compromised servers, or abusive shared hosting environments. Immediate investigation and remediation are recommended.
Does this tool store or log my domain information?
No domain information is stored or logged. All checks are performed in real time using DNS queries and blacklist lookups. The analyzer does not retain or track submitted domain data.
