Post-Purchase Cross-Sell

Example prompt: "Three days after a Shopify order is delivered, email the customer with 2-3 product recommendations that complement what they bought."

How to automate post-purchase cross-selling with GloriaMundo

The Problem

The window after a purchase is when customers are most receptive to your brand, yet most shops let it pass without any follow-up beyond the delivery confirmation. Cross-sell and upsell recommendations can increase average lifetime value by 15-20%, but crafting personalised product suggestions for each customer is time-consuming. Generic "you might also like" emails feel impersonal and perform poorly. Dedicated email marketing tools offer product recommendation features, but setting them up and maintaining product mapping rules is its own project.

How GloriaMundo Solves It

We build a workflow that fires after a Shopify order is actually delivered — not merely dispatched. The trigger uses Shopify's delivery confirmation event (derived from the fulfilment's tracking status), so the email arrives once the customer has the product in hand rather than the moment it leaves the warehouse. An integration step retrieves the order details — what was purchased, quantities, and customer email. A code step looks up related products from your catalogue, using category and tag matching to find genuine complements (not random suggestions). An LLM step writes a short, friendly follow-up email that thanks the customer for their purchase, references the specific items they bought, and recommends 2-3 complementary products with brief reasons why each is a good fit. A conditional step checks the order value — for high-value orders, the email might include a small discount code as a loyalty gesture. An integration step sends the email via Gmail. Glass Box preview lets you review the product recommendations and email copy before the first run.

Example Workflow Steps

  1. Trigger (integration): Fires when a Shopify fulfilment's tracking status changes to delivered (not merely fulfilled/dispatched), with a configurable delay — e.g. three days after delivery confirmation.
  2. Step 1 (integration): Retrieve the order details from Shopify — products purchased, categories, tags, and customer email.
  3. Step 2 (code): Query the product catalogue for complementary items based on category and tag overlap with the purchased products.
  4. Step 3 (llm): Write a personalised follow-up email thanking the customer, referencing their purchase, and recommending 2-3 complementary products with short explanations.
  5. Step 4 (conditional): If the order value exceeds a threshold (e.g. 75 pounds), include a loyalty discount code in the email.
  6. Step 5 (integration): Send the cross-sell email via Gmail.

Integrations Used

  • Shopify — source of order details, product catalogue, and customer contact information
  • Gmail — delivers the personalised cross-sell email

Who This Is For

E-commerce store owners and marketing managers who want to increase repeat purchases and average lifetime value without manually curating product recommendation emails. Particularly effective for shops selling products with natural complements — clothing with accessories, electronics with peripherals, food with related ingredients.

Time & Cost Saved

Writing individual cross-sell emails is impractical at any volume — most shops either skip it entirely or use generic templates that underperform. This workflow personalises every follow-up automatically. Cross-sell emails typically see 3-8% conversion rates. For a shop processing 200 orders per month with an average cross-sell value of 25 pounds, even a 5% conversion rate adds 250 pounds in incremental monthly revenue at near-zero effort. The workflow uses integration, code, conditional, and LLM steps, costing a few credits per email.
