Domain Health Issues

This section covers common DNS, email authentication, and SSL problems that affect your domain. Each guide explains what went wrong, why it matters, and how to fix it.

Email Authentication

›

No DMARC policy

Your domain has no DMARC record, leaving it open to email spoofing.

›

SPF record missing

Without an SPF record, anyone can send email pretending to be your domain.

DNS

›

DNS lookup failed

The DNS resolver could not retrieve records for your domain.

›

No A record

Your domain does not resolve to an IPv4 address, so it may not be reachable.

SSL

›

SSL certificate expired

An expired certificate causes browser warnings and breaks trust with visitors.
