Understanding Results

🔍 DNS Records

These control how their domain points to Brivity. Missing records means the domain isn't fully pointed and can cause issues.

📧 Email Configuration

MX records determine where your emails go. The tool detects if they're using Google Workspace or Office 365

🛡️ DMARC Explained

DMARC helps prevent email spoofing - it tells other email servers how to handle emails claiming to be from your domain.

  • ✅ Set up correctly - DMARC is properly configured for email protection
  • ⚠️ Critically misconfigured - DANGEROUS configurations that will block legitimate emails! This includes missing policies, enforcement without monitoring, or overly aggressive reject policies
  • ❌ Not set up - Everything else: monitoring-only policies, missing reporting, partial enforcement, etc. This isn't terrible! It essentially means "not providing email protection" but your email works fine

Most small websites don't have DMARC set up. It's mainly important for businesses that send a lot of emails or need extra security. The warning status is rare but serious - it means emails might get blocked.
