Add a Post-Checkout Upsell Email Offer

Help me add a post-checkout upsell offer for my Shopify store in the [STORE_NICHE] niche:

Average order value: [CURRENT AOV]
Products to upsell: [LIST 2-3 COMPLEMENTARY PRODUCTS]


  Build a Shopify Flow that triggers within [DELAY] of an order being placed containing [MAIN_PRODUCT_CATEGORY], and emails the customer a [DISCOUNT_PERCENTAGE]% off code for [COMPLEMENTARY_PRODUCT].
  Draft the email copy: product image placeholder, one-line benefit statement, price, discount code, and a link back to the store.
  Set up a report to track how many of these codes get redeemed.


Note: an in-checkout upsell (offer shown before payment, one-click add to the same order) needs Shopify Plus checkout extensibility, which is outside Sidekick’s admin-app scope — this reaches the customer right after checkout instead.
