# Why Are UTM Parameters Not Tracked When the Embedded URL Redirects to WhatsApp?

> Discover why UTM parameters are lost when email campaign links redirect to WhatsApp, and how the app modifies tracking URLs during redirection.

## Problem

The Email campaign aimed at redirecting users to WhatsApp did not properly track the UTM parameters associated with the campaign.

## Explanation

* The UTM parameters used in the Email campaign were not tracked correctly on MoEngage because WhatsApp modifies them when the app is opened.
* When WhatsApp was opened, it changed or removed the UTM parameters, causing them to be inaccurately tracked on MoEngage for the Email campaign.

## Example

* The email you received had a redirection URL in which UTM parameters, such as utm\_source=MoEngage and utm\_medium=EMAIL were missing.
* The modified UTM parameters need to resemble utm\_source=MoEngagedue.
  <Warning>
    This is a known limitation of WhatsApp; currently, MoEngage does not have a workaround.
