shopify-admin-customer-win-back

Purpose

Segments lapsed customers — those who placed at least one order but have not purchased again within a configurable window — and tags them for re-engagement. This skill handles the Shopify-native data layer; sending re-engagement emails requires an external tool.

Prerequisites

Authenticated Shopify CLI session: shopify auth login --store <domain>
API scopes: read_customers, write_customers

Parameters

Parameter	Type	Required	Default	Description
store	string	yes	—	Store domain
format	string	no	human	`human` or `json`
dry_run	bool	no	false	Preview without tagging
inactive_days	integer	no	90	Days since last order to qualify as lapsed
min_orders	integer	no	1	Minimum lifetime order count to include
tag	string	no	win-back	Tag applied to lapsed customers
max_customers	integer	no	500	Maximum customers to process per run

Workflow Steps

OPERATION: customers — query Inputs: filter last_order_date:<(NOW - inactive_days days), orders_count:>=(min_orders), first: 250, pagination Expected output: List of customer objects with id, defaultEmailAddress { emailAddress }, firstName, lastName, ordersCount, lastOrder.processedAt; paginate until hasNextPage: false
OPERATION: tagsAdd — mutation Inputs: Customer id, tag string from tag parameter Expected output: Confirmation per customer; collect userErrors

GraphQL Operations

# customers:query — validated against api_version 2025-04
query LapsedCustomers($first: Int!, $after: String, $query: String) {
  customers(first: $first, after: $after, query: $query) {
    edges {
      node {
        id
        defaultEmailAddress {
          emailAddress
        }
        firstName
        lastName
        ordersCount
        lastOrder {

          totalPriceSet {

# tagsAdd:mutation — validated against api_version 2025-01
mutation TagsAdd($id: ID!, $tags: [String!]!) {
  tagsAdd(id: $id, tags: $tags) {

      id
    }
    userErrors {
      field
      message
    }
  }
}

Session Tracking

Claude MUST emit the following output at each stage. This is mandatory.

On start, emit:

╔══════════════════════════════════════════════╗
║  SKILL: Customer Win-Back                    ║
║  Store: <store domain>                       ║
║  Started: <YYYY-MM-DD HH:MM UTC>             ║
╚══════════════════════════════════════════════╝

After each step, emit:

[N/TOTAL] <QUERY|MUTATION>  <OperationName>
          → Params: <brief summary>
          → Result: <count or outcome>

If dry_run: true, prefix mutation steps with [DRY RUN] and do not execute.

On completion, for format: human:

══════════════════════════════════════════════
OUTCOME SUMMARY
  Lapsed customers found:  <n>
  Customers tagged:        <n>
  Errors:                  <n>
  Output:                  winback_<date>.csv
══════════════════════════════════════════════

For format: json, emit the standard JSON schema with outcome keys: lapsed_found, customers_tagged, errors, output_file.

Output Format

CSV winback_<YYYY-MM-DD>.csv with columns: customer_id, email, first_name, last_name, orders_count, last_order_date, tag_applied

Error Handling

Error	Cause	Recovery
`THROTTLED`	Rate limit	Wait 2s, retry up to 3 times
`userErrors` on tagsAdd	Customer not found or invalid ID	Log, skip, continue

Best Practices

Use a dated tag (e.g., win-back-2026-04) so you can track which cohort was targeted each month and avoid re-tagging customers who already received a win-back campaign.
Set min_orders: 2 to focus on customers who had a genuine purchase relationship, not one-time buyers who may never have intended to return.
Run with dry_run: true first to validate the lapsed customer count before tagging — the count informs the scale of your re-engagement campaign.
