Domain Health
Overall reputation and deliverability status of sending domain.
What is Domain Health?
Domain health is the overall condition of your sending domain's reputation, authentication, and deliverability status. It's a composite measure of whether your emails are likely to reach the inbox based on your domain's history and current practices.
Domain Health Components:
| Component | What It Measures | Impact |
|---|---|---|
| Reputation Score | How email providers view your domain | Primary factor |
| Authentication | SPF, DKIM, DMARC status | Required for 2024 |
| Placement Rate | % reaching inbox vs spam | Actual results |
| Engagement | Opens, clicks, replies | Future predictor |
| Complaints | Spam reports | Damage indicator |
| Bounces | Failed deliveries | Health killer |
Healthy domain = emails reach the inbox. Unhealthy domain = emails go to spam or get blocked.
Why Domain Health Matters
Gmail inbox placement dropped from 89.8% to 87.2% in 2024 despite improved practices, indicating email providers are getting more stringent. Domain health is now more critical than ever.
Health Impact on Business:
- Deliverability: Unhealthy domains see 50%+ lower inbox placement
- Revenue: Poor placement = fewer opens = fewer responses = less revenue
- Sender Score: Domain health affects all future sending
- Time to Recovery: Damaged domains take months to heal
- Alternative Cost: May need to abandon domain and start over
Benchmarks
| Health Indicator | Excellent | Good | Poor |
|---|---|---|---|
| Reputation Score | 90-100 | 80-89 | Below 70 |
| Inbox Placement | 90%+ | 85-90% | Below 80% |
| Bounce Rate | <1% | 1-2% | >3% |
| Spam Complaints | <0.05% | 0.05-0.1% | >0.2% |
| Engagement Rate | High | Moderate | Low |
Recovery Timeline:
- Minor damage: 2-4 weeks to recover
- Moderate damage: 1-2 months
- Severe damage: 3-6 months or abandon domain
Best Practices
- Monitor Weekly: Check domain health metrics every week
- Use Testing Tools: Regular deliverability tests catch issues early
- Fix Problems Fast: Address health issues before they compound
- Maintain Authentication: Keep SPF, DKIM, DMARC current
- Clean Lists Regularly: Remove inactive and invalid addresses
- Respect Spam Complaints: Remove compliers immediately
- Track by Provider: Monitor Gmail vs. Outlook separately

- Sending from domains with past reputation issues
- Not having alternative domains ready
- Confusing delivery rate with inbox placement
