Hi @Rachel T,

Welcome to the Klaviyo Community and thank you for your question! 

You can absolutely add A/B tests into your flow. You can do this in one of two ways:

1. Test the actual email itself - you can create a B variant of the individual email/SMS inside of the flow. This can be done through the email editor, and this will allow you to A/B test on the content of the email (example - subject line, content inside email etc). More information about that in this article.
2. Create a random sample in a flow of 50% - this will allow you to test the actual flow pathway. This is helpful if you want to test the wait steps or channel used. For example - let’s say I wanted to test if an email or an SMS is more successful. You do this through a conditional split and selecting “Random Sample”. This would look something like the below: 

   

    

In short, yes you can add A/B tests to existing flows. I hope that answers your question!

Thanks
David
