# Domain Health

Overall reputation and deliverability status of sending domain.

[Back to glossary](/sales/glossary/)

## 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
**The 2024 Reality**: Gmail and Yahoo now require authentication AND healthy sending practices. Domain health encompasses both technical setup and sending behavior.

## 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

1. **Monitor Weekly**: Check domain health metrics every week
2. **Use Testing Tools**: Regular deliverability tests catch issues early
3. **Fix Problems Fast**: Address health issues before they compound
4. **Maintain Authentication**: Keep SPF, DKIM, DMARC current
5. **Clean Lists Regularly**: Remove inactive and invalid addresses
6. **Respect Spam Complaints**: Remove compliers immediately
7. **Track by Provider**: Monitor Gmail vs. Outlook separately
8. **Have Backup Domains**: Never rely on single domain

## Common Mistakes

* Not checking domain health until problems are severe
* Ignoring early warning signs (slight placement decline)
* Assuming because emails "send" they're being delivered
* Not monitoring spam folder placement
* Letting bounce rates climb before acting
* Sending from domains with past reputation issues
* Not having alternative domains ready
* Confusing delivery rate with inbox placement

## Key Takeaways

* Domain health = overall condition of your email sending reputation
* Check health weekly using testing tools and provider dashboards
* 90+ reputation score and 85%+ inbox placement = healthy
* Gmail placement dropped to 87.2% in 2024-health matters more than ever
* SPF, DKIM, and DMARC are required but not sufficient for health
* Engagement, bounce rates, and spam complaints all affect health
* Damaged domains take months to recover-prevention is critical
* Have backup domains ready in case of health issues
