# How to use the Random Split feature?

With the Random Split feature, divide users into random groups to run tests, optimize your journey or set up a control group logic. Let's go through the steps together :sparkles:

{% step %}

## Add a trigger event and a Random Split

Select your trigger event, then add a Random Split at any step of the omnichannel trigger automation.

To do so, simply click on the **+** button and select **Yes/No Split:**

{% endstep %}

{% step %}

## Customize the branches

Customize the branches as you wish!&#x20;

Click on the **+** button again to add messages, delays, exit events or another split:

{% endstep %}

{% step %}

## Adjust the percentages

Create from 2 to 4 branches and adjust the percentage of users for each of them. Just keep in mind that the sum of branches must always be 100%.

{% hint style="warning" %}
The algorithm for randomization is **efficient for high volumes** but less so for very low volumes. If 30 people receive the automation and the automation has 3 branches (33%, 33%, 34%), you might not have exactly 10 people by branch.
{% endhint %}

🔍  With this feature, automations can get a lot bigger: to get a better overview, use the **mini-map** at the bottom-left corner of your screen to navigate and zoom in and out in the automation:

{% endstep %}
{% endstepper %}

You are now ready to create your own journey using the Random Split feature :rocket:
