# How to Find Users With Bounced Emails?

> Identify users with hard-bounced or soft-bounced emails in MoEngage using campaign IDs, segmentation filters, and user attribute-based queries.

## Problem

Unable to identify users with bounced emails.

## Explanation

* An email hard bounce occurs when the MoEngage system detects that the recipient's email address does not exist. This tracking is unique for each user based on their user ID.
* An email soft bounce is tracked in the MoEngage system when there is a temporary delivery issue. This tracking is unique for each user based on their user ID.

## Solution

Perform the following steps:

1. Go to the desired Email campaign to identify users who have encountered bounced emails.
2. Copy the campaign ID.

3. Hover over to the left menu and select **Segment** > **Create segment**.
4. While creating the segment, use the **OR** condition instead of the **AND** condition between the *Email Bounced* and *Email Soft Bounced* events in the nested filters.

## Example

* As shown in the following screenshot, the first filter searches for users who experienced at least one hard email bounce in the past 30 days.

* The second filter searches users who experienced at least one soft bounce in the past 30 days.

* In both filters, the **Readable Campaign Id** (case-insensitive and dependent on a specific scenario) matches the specified value.
* As a result, hard or soft bounce emails associated with **Readable Campaign Id** in the past 30 days will be identified as true.
