When you launch something that pairs with an existing product — matching jeans for a jacket, refills for a device, a sequel to a bestseller — the warmest possible audience is the customers who already bought the original. They've proven they want this category. The hard part is pulling that exact list out of Shopify.
Why this list is hard to get
Shopify doesn't offer a simple "show me everyone who bought product X" view. You'd have to dig through orders, match line items to customers, and dedupe — tedious enough that the cross-sell opportunity usually passes you by.

Why targeted beats broad
Emailing your whole list about matching jeans is noise; emailing the 38 people who bought the jacket is a relevant recommendation. Product-based targeting like this consistently outperforms broad blasts — and it's only practical when building the list takes a sentence, not an afternoon.
