The Split Randomly action can be used for randomly passing your contacts through equally-distributed pathways in your flow.
In the example below, we’re immediately splitting contacts who enter a flow into two different groups named “A Flow” and “B Flow”.
We’ve ended there in our example, but you could go on to start those contacts in a flow or any number of other actions or Split Actions.
Split Randomly is particularly helpful for the purpose of randomly branching a contact for an A/B test or the like. See this guide for more information on A/B testing.
