--- title: "Automate Shopify Abandoned-Cart Emails with n8n and AI" description: "Build a Shopify abandoned-cart email workflow in n8n. AI personalizes every win-back message. No OpenAI key needed — AI credits are included on AgentRoost." canonical: https://agentroost.app/en/blog/shopify-abandoned-cart-emails-n8n-ai date: 2026-06-13T12:00:00Z --- [Canonical URL](https://agentroost.app/en/blog/shopify-abandoned-cart-emails-n8n-ai) About 70% of online shopping carts are abandoned before checkout. A well-timed email — one that speaks to what the customer actually left behind — recovers a meaningful slice of those lost sales. Generic "You left something behind!" templates recover some of them. An email that says *"You were this close to getting the Merino Wool Crew-Neck in forest green — here's why it's worth coming back"* converts significantly better. This guide walks through building exactly that: a running n8n workflow that catches Shopify checkout abandonment events in real time, waits the right amount of time, then asks an LLM to write a personalized, product-specific email — and sends it. --- ## How the workflow fits together The flow has five stages: ``` Shopify Webhook → Wait → Check if order placed → AI writes email → Send Email ``` Each stage maps to specific n8n nodes. Let's build it step by step. --- ## Step 1 — Receive the abandonment event from Shopify **Node: Webhook** Shopify fires a `checkouts/create` or `checkouts/update` event when a customer fills in their email and adds items but doesn't complete the purchase. You'll catch this with a Webhook node. In your n8n canvas, add a **Webhook** node. Set the method to `POST`, copy the generated URL — it will look like `https://.agentroost.app/webhook/shopify-cart` — and paste it into Shopify: > Shopify Admin → Settings → Notifications → Webhooks → Create webhook > Event: `Checkout creation` (and optionally `Checkout update`) > Format: JSON > URL: your Webhook node URL The payload arrives with everything you need: `email`, `line_items` (product titles, quantities, prices), `subtotal_price`, and `abandoned_checkout_url` (Shopify's recovery link). --- ## Step 2 — Wait before sending anything **Node: Wait** Don't email immediately. Customers who abandon a cart sometimes complete the purchase within 30–60 minutes on a different device or after a phone call. Emailing them mid-checkout looks pushy and creates confusion if they do convert. Add a **Wait** node after the Webhook. Set it to **1 hour** (or 30 minutes for faster-moving products). The workflow suspends here — no polling, no memory usage — and resumes automatically when the timer fires. --- ## Step 3 — Check whether the order was placed in the meantime **Node: HTTP Request + IF** Before sending anything, verify the cart is still abandoned. Use the **HTTP Request** node to call the Shopify REST API: ``` GET https://{{$node["Webhook"].json.domain}}/admin/api/2024-07/checkouts/{{$node["Webhook"].json.token}}.json ``` Add your Shopify API credentials (Admin API access token) in the **Header Auth** credential. The response includes a `completed_at` field — it's `null` if the cart is still open, or a timestamp if the order went through. Add an **IF** node: - Condition: `{{$node["HTTP Request"].json.checkout.completed_at}}` is **empty** - True branch → continue to email - False branch → **NoOp** (do nothing, order was placed) This prevents you from emailing someone who already bought. --- ## Step 4 — Let the AI write a personalized email **Node: AI / LLM** This is where generic tools fall short. Instead of a fixed template, you give the LLM the cart contents and ask it to write something specific and useful. Add a **Basic LLM Chain** node (under the AI section). In the **System Message**, put something like: ``` You are a friendly email copywriter for an e-commerce brand. Write a short, warm abandoned-cart recovery email. Be specific about the products. No hard-sell language. Include a clear call-to-action at the end. Max 120 words. ``` In the **User Message**, use an expression that pulls the actual cart data: ``` The customer {{$node["Webhook"].json.email}} left these items: {{$node["Webhook"].json.line_items.map(i => `- ${i.title} x${i.quantity} ($${i.price})`).join('\n')}} Cart total: ${{$node["Webhook"].json.subtotal_price}} Recovery link: {{$node["Webhook"].json.abandoned_checkout_url}} Write the email. ``` The AI output is a natural, product-aware win-back message — different for a customer who left $12 of face wash than for someone who left $380 of camera gear. --- ## Step 5 — Send the email **Node: Send Email (SMTP) or Gmail** Add a **Send Email** node (or the **Gmail** node if you prefer OAuth). Wire it up: - **To**: `{{$node["Webhook"].json.email}}` - **Subject**: something like `Still thinking it over?` or use another short AI call to generate a subject line - **Body (HTML)**: `{{$node["LLM"].json.text}}` - **From**: your store's sender address For SMTP, you'll need your email provider credentials (Gmail app password, SendGrid, Brevo, etc.) stored in an n8n credential. The node stays generic — you're just pointing it at your existing email infrastructure. --- ## Handling edge cases **Duplicate triggers**: Shopify can fire `checkouts/update` multiple times. Add a **Set** node early in the flow to extract the cart `token`, then use n8n's built-in **Deduplication** node (available in recent n8n versions) keyed on that token. Only the first event per token proceeds. **Unsubscribed customers**: If you maintain a suppression list in a Google Sheet or Airtable, add an **HTTP Request** (or native node) to check it before the Wait step. If the customer is on the list, route to NoOp. **Test with a real checkout**: Shopify's webhook test tool sends a sample payload but it won't have a real `abandoned_checkout_url`. Do one real checkout-dropout on your store (use a personal email) to see the actual payload shape before going live. --- ## Run this on AgentRoost — no DevOps required Building this locally means managing Docker, SSL certificates, a public hostname for the Shopify webhook, uptime monitoring, and your own OpenAI API key. All of that adds up before you've sent a single recovery email. On AgentRoost, you get your own n8n instance — your login, your workflows, your data — running 24/7 on a public subdomain (`https://.agentroost.app`). The AI/LLM nodes are already wired to included credits. You don't create an OpenAI account, you don't enter an API key, you don't monitor usage dashboards. The AI node just works. **How to set it up:** 1. Sign up at [agentroost.app](/en/pricing) — from $19.99/mo, 14-day money-back guarantee. 2. Create a new workspace, pick the **n8n** framework, give it a name. 3. Your private n8n editor opens at `https://.agentroost.app` within about 2 minutes. 4. Import or build the workflow above. The Webhook node's URL is already public HTTPS — paste it into Shopify immediately. 5. Activate the workflow. It runs 24/7 without you keeping a laptop open. The included AI credits cover the LLM calls for email generation. As your volume grows, Plus and Pro tiers add more compute and more included credits.

Keep it to a maximum of 2 emails per cart — more than that starts hurting sender reputation. - **UTM-tag the recovery link**: append `?utm_source=email&utm_medium=cart-recovery&utm_campaign=abandonment` to `abandoned_checkout_url` so you can track recovery conversions in Google Analytics separately from organic traffic.
