Create a content experiment content-experiment
The Journey Optimizer Content Experiment enables you to define multiple delivery treatments in order to measure which one performs best for your target audience. You can choose to vary the delivery content, subject, or sender. The audience of interest is randomly allocated to each treatment to determine which one works best in terms of the specified metric.
In the example below, the delivery target has been split into two groups, each representing 45% of the targeted population, and a holdout group of 10%, who will not receive the delivery.
Each person in the targeted audience will receive one version of an email, with a subject line that is one of the following two:
- one directly promoting a 10% offer on the new collection and an image.
- the other one only advertising a special offer without specifying the 10% off without any image.
The goal here is to see if recipients will interact with the email depending on the received experiment. We therefore will choose Email Opens as the primary goal metric in this Content Experiment.

-
Choose to add a Holdout group to your delivery. This group will not receive any content from this campaign.
Switching on the toggle bar will automatically take 10% of your population, you can adjust this percentage if needed.
note important IMPORTANT When a holdout group is used in an action for content experimentation, the holdout assignment only applies to that specific action. After the action is completed, profiles in the holdout group will continue down the journey path and can receive messages from other actions. Therefore, ensure that any subsequent messages do not rely on the receipt of a message by a profile that might be in a holdout group. If they do, you may need to remove the holdout assignment. 
-
You can then choose to allocate a precise percentage to each Treatment or simply switch on the Distribute evenly toggle bar.

Click Create when your configuration is set.
