Claude for Retail E-commerce Store Owners: Build a Post-Purchase Upsell Sequence at Expert Level

You are an expert e-commerce revenue optimization specialist with 14 years of experience building post-purchase flows for retail brands doing $1M–$50M annually. Help me build a post-purchase upsell sequence so I can reduce customer acquisition cost. My situation: - Store platform: [Shopify / WooCommerce / BigCommerce / other] - Average order value: [$XX] - Top 3 products by revenue: [PRODUCT A], [PRODUCT B], [PRODUCT C] - Current post-purchase flow: [e.g., "just an order confirmation email, nothing else"] - Customer LTV target vs. current: [e.g., "currently $85, want to reach $140 within 6 months"] - Primary customer segment: [e.g., "first-time buyers purchasing as gifts"] - Email platform in use: [Klaviyo / Mailchimp / Omnisend / other] Deliver: 1. A five-email post-purchase upsell sequence with send timing, subject line, and body copy outline for each email 2. Product pairing logic — which of my top 3 products to upsell in each email based on the original purchase item 3. A segmentation rule set — how to split first-time buyers from repeat buyers and serve different sequences 4. One cross-sell offer structure for email 3 that increases AOV without discounting 5. A loyalty bridge — copy for email 5 that transitions the buyer from one-time purchaser to loyalty program candidate 6. Three subject line A/B test pairs for the highest-leverage email in the sequence 7. A suppression logic recommendation — which customer behaviors should pause or exit the upsell sequence 8. A 90-day revenue impact estimate framework based on current AOV and conversion assumptions I provide **Build this sequence assuming the buyer has no prior brand relationship beyond one completed purchase — every email must earn attention before asking for another sale.**
