# How Sender Reputation Impacts Inbox Delivery (And How AI Helps)

### 🌟 What Is Sender Reputation — and Why It Matters

Sender reputation is like your **credit score for email**. Mailbox providers such as Gmail, Outlook, and Yahoo assign a trust rating to your domain and IP based on your sending behavior.

📬 A **good reputation** gets you into the inbox. A **bad one**? Straight to spam — or blocked entirely.

If you’re serious about inbox delivery, sender reputation should be a top priority. And in 2025, **AI is becoming a game-changer** for how it’s managed.

### 🧩 Key Factors That Affect Sender Reputation

Mailbox providers don’t publish their exact algorithms, but reputation is shaped by a mix of **negative and positive signals**:

#### 📉 Negative Signals

* High bounce rates
* Spam complaints
* Sudden spikes in volume
* Poor list hygiene (sending to invalid addresses)
* Low engagement (opens, clicks, replies)

#### 📈 Positive Signals

* Consistent sending volume over time
* Replies to your emails
* Users marking your emails as "Not Spam"
* High open and click rates
* Low bounce and unsubscribe rates

🛠️ **Maintaining these metrics consistently is how good senders earn long-term inbox trust.**

### 🌐 Domain vs. IP Reputation

* **IP reputation** applies to your server’s IP address.
* **Domain reputation** applies to the email domain (e.g., `you@yourdomain.com`).

🔑 In recent years, **domain reputation has become more important than IP**, especially for senders using shared infrastructures.

💡 **Pro Tip:** For cold email or high-volume campaigns, rotate between **properly warmed-up subdomains** like `mail.domain.com`, `outreach.domain.com`, etc.
