# Domain Reputation

How email providers view your domain based on sending behavior and engagement.

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

## What is Domain Reputation?

Domain reputation is the score that mailbox providers (Gmail, Outlook, Yahoo, etc.) assign to your sending domain based on your sending history and recipient engagement. It's like a credit score for email-higher scores mean better treatment.

**Reputation Factors:**

| Factor          | Weight   | How It's Measured                      |
| --------------- | -------- | -------------------------------------- |
| Bounce Rate     | High     | % of emails that fail to deliver       |
| Spam Complaints | Critical | Users marking emails as spam           |
| Engagement      | High     | Opens, clicks, replies                 |
| Sending Volume  | Medium   | Consistency and patterns               |
| Authentication  | Required | SPF, DKIM, DMARC setup                 |
| Age of Domain   | Medium   | New domains start with zero reputation |

Each mailbox provider calculates reputation differently, but they all track similar signals. Good reputation = inbox placement. Bad reputation = spam folder.

## Why Domain Reputation Matters

**Your domain reputation is the single biggest factor in email deliverability.** Even perfect emails will go to spam if sent from a domain with poor reputation.

**Reputation Impact:**  
* **Inbox Placement**: 90%+ for excellent reputation, below 50% for poor
* **Sending Limits**: Poor reputation = aggressive volume restrictions
* **Filter Sensitivity**: Low reputation = every email scrutinized
* **Recovery Time**: Damaged reputation takes 1-6 months to rebuild
* **Domain Replacement**: Severely damaged domains must be abandoned
**The Algorithm's View**: Email providers want to protect users from spam. They track every send, every bounce, every complaint. Your reputation is your track record.

## Benchmarks

| Reputation Score | Status    | Inbox Placement |
| ---------------- | --------- | --------------- |
| 90-100           | Excellent | 90%+            |
| 80-89            | Good      | 85-90%          |
| 70-79            | Fair      | 70-85%          |
| 60-69            | Poor      | 50-70%          |
| Below 60         | Critical  | <50%            |

**Critical Thresholds:**  
* **Spam complaints above 0.3%**: Rapid reputation decline
* **Bounce rate above 2%**: Reputation damage accelerates
* **Low engagement**: Even if bounces are low, no engagement = poor reputation
* **New domain**: Starts at zero, must build over 14-21 days

## Best Practices

1. **Warm Up Gradually**: Build reputation slowly with new domains
2. **Keep Bounces Below 2%**: Remove hard bounces immediately
3. **Monitor Complaints**: Stay below 0.1% spam complaint rate
4. **Maintain Engagement**: Remove consistently non-engaging subscribers
5. **Send Consistently**: Regular patterns build trust
6. **Authenticate Fully**: SPF, DKIM, DMARC are required
7. **Check Regularly**: Use Google Postmaster Tools and other monitoring
8. **Protect Your Reputation**: One mistake can undo months of work

## Common Mistakes

* Sending high volume from new domains without warmup
* Ignoring spam complaints until reputation is destroyed
* Not removing hard bounces immediately
* Buying email lists (reputation suicide)
* Sending to inactive subscribers repeatedly
* Not checking reputation scores regularly
* Assuming reputation is the same across all providers
* Trying to "game" the system (providers catch on)

## Key Takeaways

* Domain reputation is your email sending credit score (0-100)
* 85+ is good, 90+ is excellent for deliverability
* Reputation determines inbox placement more than any other factor
* Bounce rates, spam complaints, and engagement drive reputation
* New domains start at zero and need 14-21 days warmup
* Damaged reputation takes 1-6 months to recover
* Check reputation weekly using Google Postmaster Tools
* Protect your reputation-it's harder to rebuild than to maintain
