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
