Hi @MariekeUNC,
Depending on what settings you choose Klaviyo will either distribute based on the distribution you've set (i.e. 50%/50%) or an automatic distribution using a multi armed bandid to distribute more traffic to the winning variation to make sure you’re also capitalizing as much as possible.
Now as for your question it sounds like you want to both A/B test an email and also the path that people take depending on the first email they got (A or B).
I would make sure you have a good hypothesis you're testing first either it's the email itself or a sequence of emails (a path).
For a sequence of email you'll need to add a split somewhere, either at the beginning and add a 50/50 random sample conditional split and see which path works best
Or test the email first and have an a/b test running to see which works best and then follow up. You could however add a split after the email a/b test that creates 2 paths depending on which email someone received in the test. IF you want to do this please use, “what someone has done” in the conditional split and choose received email (and find the correct email or email attribute that distinguishes the emails in the a/b test.)
I hope this helps!
