Suppose there’s a brand. They do like 50 grand a month... They got tons of lists on Shopify...They imported the list into Klaviyo. Now every emails is showing as subscribed to email marketing. They never send any emails. Although sent a few emails through Shopify on major holidays.
Now, how do you filter out those emails? How to clean the list at that point? There's nothing such as email opens or something like that right? What would you do?
