# How to Improve Email Sender Reputation

Recover your domain status, fix deliverability issues, and make sure your emails land back in primary inboxes.

If your domain reputation takes a sudden hit or ends up on a blocklist, your emails can quickly start bouncing or landing straight in spam folders. Taking immediate, targeted steps helps your team stop reputation damage, rebuild domain trust, and get delivery rates back on track.

To understand how inbox providers evaluate your domain performance, check out “[What is Email Sender Reputation](https://help.user.com/en/articles/145-what-is-email-sender-reputation.md)”.

> **Info:** Repairing a dropped domain reputation takes time and consistent habits - expect recovery to take between 30 and 60 days.

Follow these core practices in Positive User to stabilize your domain status and rebuild your sending score.

## Step-by-Step

### 1\. Pause Broad Marketing Campaigns

Pausing broad promotional sends and cold outreach immediately halts the stream of negative deliverability signals, such as high spam complaint rates, hard bounces, and unengaged opens. Stopping these messages gives your domain a cooling-down period and prevents further loss of sender reputation while you investigate.

### 2\. Audit Recent Imports and Problem Data

Sudden reputation drops are usually caused by a single event, such as uploading an unverified contact list or receiving spam bot sign-ups through public forms. Auditing performance trends by date helps you pinpoint the exact source, group affected contacts, and delete invalid addresses before they cause further hard bounces.

### 3\. Send Targeted Campaigns to Super-Engaged Contacts

Rebuilding domain standing requires proving to email providers that your messages are valued. Sending small, personalized campaigns strictly to contacts who opened or clicked an email in the last 7 to 14 days generates high open rates that outweigh previous negative events.

### 4\. Submit Delisting Requests to Providers

Once you resolve the root cause of complaints and establish strong positive engagement, submitting a formal delisting appeal informs security blocklists and inbox providers that your domain is secure and compliant. Clearing these flags restores your domain's ability to reach primary inboxes.

## Important Note

Keep these guidelines in mind while restoring your domain score:

-   **Expand Audiences In Stages:** After establishing consistent opens with super-engagers (7–14 days), expand your sends gradually: move to contacts active in the last 30 days, then 90 days, and finally 180 days as placement improves.
    
-   **Never Use Purchased Lists**: Always collect addresses through explicit opt-ins. Purchased or rented lists contain spam traps that immediately damage domain standing.
    
-   **Track External Reputation Scores**: Combine Positive User analytics with third-party tools like Google Postmaster Tools to track how major email services rate your domain score.
