With the Random split feature, divide users into random groups to run some tests, optimize your journey or even set up a control group logic.

What is the Random split feature?

The Random Split allows you to divide the users of an automation into 2 to 4 groups based on algorithms. You may choose the percentage of users entering each group according to your use case and customize everything on the branch such as delays or cancellation events.

This allows you to test and optimize use cases. Try different series of messages, various delays and times of sending, other content and types of messages. Learn more about use cases in our Blog's article 👈

Let's now see how to create these branches!

How to use it?

Once you have chosen the trigger event, you can add the Random Split at every step of an omnichannel trigger automation. Click on the + button and then select Random split:

Then customize the branches as you wish! By clicking again on the +, add messages, delays, cancellation events or even another split on the branches.

Choose between 2, 3 or 4 branches and adjust the percentage of users of each of them. Just keep in mind that the sum of branches must always be 100%.

💡 The algorithm for randomisation is efficient at high volumes but less at very low volumes. If you send 30 people in the automation for a test and have 3 (33%, 33%, 34% branches) you might not have exactly 10 people by branch.

Also, with this feature, automations can get a lot bigger: to get a better overview, use the mini-map representing the whole automation at the bottom right of your screen to navigate and zoom in and out in the automation.

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