I have a really large email list, and I would like to test a very small segment on several email variations before sending to everyone. My idea is to put Klaviyo into manual mode, load up the flow, then send about 10% of the emails in Needs Review and measure the results.
My question is when does Klaviyo evaluate the weights for the email variations? Is it when the group of emails are first loaded into Needs Review? Or does it evaluate the weights at the time of the emails are actually sent? I'm wondering that if I change the variation weights, will Klavio take that into account immediately.
Thank you!
