DNS Health Analyzer
Analyze a domain's DNS and email configuration with intelligent health scoring.
Domain analysis
Interprets DNS records for email health, not just raw displayWhat is DNS Health Analyzer?
DNS health analysis reviews the records that keep a domain reachable and mail-authenticated — including MX and related policy records.
How it works
Provide a domain and PacketWizard evaluates key DNS surfaces used in uptime and email authentication workflows, surfacing gaps and inconsistencies.
Common issues
Mail fails but website works
A and AAAA can be fine while MX/TXT policy records are wrong. Check mail-specific records explicitly.
Frequently asked questions
Is DNS health the same as a single DNS lookup?
No. A single lookup answers one query. Health analysis looks across the records that typically matter for domain and mail operations.
