This guide is specific to Batch's Mobile Engagement Platform (More on the [difference between Batch's CEP and MEP](https://app.gitbook.com/s/UIK868wiiK9XOVyETGZS/other/faq/what-are-the-differences-between-batch-customer-engagement-platform-and-mobile-engagement-platform)).

In-App messages allow you to trigger a wide variety of actions when users click a button, including opening the default phone, SMS, or email app with a predefined phone number or email address. This can be done by using links such as :
* **tel:+00XXXXXXXXX**: opens the default phone app. Users just need to press the call button to call the phone number included in the link.
* **sms:+00XXXXXXXXX**: Creates a draft in the default SMS messaging app. Users only need to type a message and click "Send" to send an SMS to the linked phone number.
* **mailto:**[**example@domain.com**](mailto:example@domain.com): Creates a draft in the default emailing app. Users only need to type a message and click "Send" to contact the linked email address
These links are handy to improve the user experience by redirecting them to the default apps and pre-filling the phone number/email address they need to contact, instead of asking them to copy-paste a value, and then open manually their phone/messaging app.
Here is a quick guide on how to use these links in an In-App automation or a Mobile Landing:
## Creating a "Call" button in an In-App message
To be able to redirect users to their phone application you must:
1. Open or create a campaign
2. Go into the advanced settings and add the following format as a deeplink of the In-App message button: `tel:+33123456789`
{% hint style="info" %}
The "**Open in app**" and "**Open in browser**" options do not affect the redirection.
{% endhint %}
Depending on their device, here is what the redirect could look like once users click the "**Contact Us**" button:
## Creating a "Text" button in an In-App message
## Creating an "Email" button in an In-App message
To be able to redirect users to their email application you must:
1. Open or create a campaign
2. Go into the advanced settings and add the following format as a deeplink of the In-App message button: `mailto:experts@batch.com`
{% hint style="info" %}
The "**Open in app**" and "**Open in browser**" options do not affect the redirection.
{% endhint %}
Depending on their device, here is what the redirect could look like once users click the "**Contact Us**" button:
{% hint style="info" %}
We recommend **adding an emoji** that clarifies the action that will follow in the CTA.
Ex: ✉️ Contact us vs 📞 Contact us
