Domain Health Score

A healthy domain configuration is essential for reliable email delivery. Missing or misconfigured DNS records can cause your emails to land in spam folders, be rejected outright, or make your domain vulnerable to spoofing.

SPF (Sender Policy Framework) and DMARC (Domain-based Message Authentication, Reporting & Conformance) records are critical email authentication mechanisms. Together with DKIM, they form the foundation of email security and deliverability.

Having IPv6 (AAAA) records is increasingly important as more mail servers adopt IPv6. While not strictly required, it demonstrates a modern, well-maintained domain infrastructure.
