*newbie alert* apologies if this is basic 101.
Somebody (from Klaviyo) created an everybody list for us on our account when we were setting up our account. I have a feeling it was to make sure all suppressed addresses were captured however I’d like to see the ‘rules’ or definitions on how this list comes together so that I can ensure that our Shopify people are being feed into this ‘everybody’ list, but I cannot seem to find any information on how those names get on the list.
