Understanding Email Metrics

Domain Reputation

Google assigns reputation scores to domains based on email sending practices:

Reputation Level Description
HIGH Excellent reputation - your emails are trusted
MEDIUM Good reputation - minor issues may exist
LOW Poor reputation - significant issues affecting delivery
SPAM Very poor reputation - emails likely marked as spam

IP Reputation

Similar to domain reputation but tracked for individual IP addresses. Important for dedicated sending infrastructure.

Spam Rate

Percentage of emails marked as spam by recipients. Keep this below 0.1% for best deliverability.

Authentication

Tracks SPF, DKIM, and DMARC authentication success rates. Aim for 100% authentication.

Best Practices

Maintain High Reputation

  • Send only to engaged subscribers
  • Remove inactive addresses regularly
  • Honor unsubscribe requests immediately
  • Avoid purchased or rented lists

Improve Authentication

  • Set up SPF records correctly
  • Implement DKIM signing
  • Configure DMARC policy
  • Monitor authentication reports

Monitor Regularly

  • Check reputation daily
  • Set up alerts for reputation drops
  • Investigate spam rate increases
  • Track authentication failures
