Help me understand the View Product metric!

I’m brand new to Klaviyo, and I’m hoping someone can help me understand the ‘View Product’ event and how it triggers the browse abandonment flow on my Shopify site.

I have a browse abandonment flow setup, using the template provided in Klaviyo. I’ve tested the trigger and flow as instructed, and it seems to work when I try it on my own profile/email. I get the browse abandonment flow email just fine.

However, when I uploaded a small section of my existing subscriber list to Klaviyo and sent my first test campaign, it didn’t seem to work at all. A total of seven people clicked through from the Klaviyo campaign email directly to a particular product page on my site. They’re showing as converting to the “View Product” metric, but none of them triggered the flow. I feel like I’m missing something, but I just don’t get what. 

Thanks so much for your help!
