Health Monitoring System

FireGlue's Health Monitoring system provides real-time insights into your domain and mailbox health, helping you maintain optimal email deliverability.

Overview​

The Health Monitoring system continuously tracks:

  • Domain Health Scores - Overall domain reputation
  • Mailbox Health - Individual mailbox performance
  • DNS Record Status - SPF, DKIM, DMARC validation
  • Deliverability Metrics - Bounce rates, complaint rates, open rates
  • Alert System - Real-time notifications for issues

Health Score Calculation​

Domain Health Score (0-100)​

The health score is calculated based on multiple factors:

Reputation Factors (40%)​

  • Domain Age: Older domains score higher
  • Sending History: Consistent patterns improve scores
  • Volume Consistency: Gradual increases vs. sudden spikes

Deliverability Metrics (35%)​

  • Bounce Rate: Target < 5%
  • Complaint Rate: Target < 0.1%
  • Spam Trap Hits: Should be 0
  • Blacklist Status: Clean domains score higher

Technical Factors (25%)​

  • DNS Configuration: Proper SPF, DKIM, DMARC
  • IP Reputation: Clean sending IPs
  • Authentication: Proper email authentication

dig TXT default._domainkey.yourdomain.com

# Check authentication
Authentication-Results: yourdomain.com; dkim=pass

DMARC Problems​

# Check DMARC policy
dig TXT _dmarc.yourdomain.com

# Monitor reports
v=DMARC1; p=quarantine; rua=mailto:[email protected]
