💙 Domain Health Checker

We analyze HTTP/HTTPS connectivity, SSL certificate validity, DNS configuration, response times, security headers, and email authentication (SPF/DKIM/DMARC). Each check contributes to an overall health score from 0-100.

Scores above 80 indicate a well-configured domain. Scores 60-80 are acceptable but have room for improvement. Below 60 suggests significant issues that may affect reliability, security, or deliverability.

Address any failing checks shown in the report: ensure valid SSL, configure proper DNS records, set up email authentication (SPF, DKIM, DMARC), and add security headers. Our detailed results show exactly what to fix.
