About Quick Scan
What Quick Scan checks
Quick Scan runs a single pass over a domain and rolls four areas into one score: DNS and registration (is the domain resolving, who runs its nameservers, when does it expire), SSL/TLS (is the certificate valid and trusted), email authentication (SPF, DKIM, and DMARC, the three records inboxes use to trust your mail), and public blacklist status. It is the fastest way to see whether a domain has an obvious problem before you dig into any one area.
How to read the result
The overall grade is a summary, not the whole story - open each section to see which specific check pulled it down. A high score with one red item usually means a single fixable record; a low score across the board usually means the domain was never fully configured for email. Registration and SSL expiry dates are worth noting even when they pass, because they are the things that break silently later.
What to do next
Fix the lowest-scoring section first - email authentication and an expired certificate cause the most visible damage. Each finding names the exact record or setting involved, so you can hand it straight to whoever manages your DNS. To catch these before they cost you, add the domain to Nexa Monitor and it will re-run the same checks on a schedule and alert you when something changes.
