# How to send yourself a test for In-App messages?

{% hint style="info" %}
This guide is specific to Batch's Mobile Engagement Platform (More on the [difference between Batch's CEP and MEP](/getting-started/other/faq/what-are-the-differences-between-batch-customer-engagement-platform-and-mobile-engagement-platform.md)).
{% endhint %}

In-App Messaging allows you to communicate with your users while they are browsing the app, even if they did not accept push notifications. You can easily send a preview to your device before turning the campaign on for all your users.

To achieve that, Batch simulates the In-App display by sending you a push notification with your In-App message displayed as a landing page in your app.  This will only allow you to see if your text and image are displayed properly. 

In the **in-app automation editor**, click the ⚙️ to select your device in the saved devices, or copy your Installation ID in the corresponding field. Hit "**Send test**":

You will receive a push notification: open it to see on your device a preview of the message you are editing.

If you don't see it right away, you should refer to the [**Mobile Landing** debugging article](https://doc.batch.com/developer/troubleshooting/my-mobile-landing-does-not-show).

{% hint style="warning" %}
Consider turning on the automation for a **development version of your app** if you want to test more than the aspect of your message (e.g. trigger, targeting, etc).
