# New Feature: Track "Sender Bounced" Emails

Understand 'Sender Bounced' emails in Smartlead and fix issues with your mailbox.

We’ve introduced a new bounce type: **Sender Bounced**. This helps you understand when an email fails due to issues with your **mailbox or email setup**, rather than the lead itself.

Now you can also filter by “Sender Bounced” on the Email Campaign section.

## What is a Sender Bounced Email?

Normally, when an email bounces, it means the recipient’s email is invalid or unreachable. **But not all bounces are the same.**

A **Sender Bounced** email happens when your message doesn’t go through because of problems with your sending setup. The lead is still valid, but something on **your end** is blocking delivery.

## Why Does an Email Get Marked as Sender Bounced?

Your email might bounce for one of these reasons:

-   **Domain misconfiguration** – Issues with **SPF, DKIM, or DMARC** settings.
    
-   **Weak sender reputation** – Your **ESP or email tenant** has a poor reputation.
    
-   **Flagged domain** – You’re sending from a domain that’s blacklisted or not properly warmed up.
    

## What Should You Do?

1.  **Try sending from a different mailbox or a properly configured domain.**
    
2.  **Don’t assume these leads are bad**—they didn’t bounce because of their email address.
    
3.  **Fix your email setup** to prevent future Sender Bounced emails and improve deliverability.
    

## **Bonus: Better Data Organization**

Along with this update, you can now:

-   **Rearrange columns** in your dashboard to focus on key data.
    
-   **See the number of leads reached vs. total emails sent** for better tracking.
    

This update gives you **more control over your email performance** so you can reach the right people without unnecessary bounces.
