What is CM Commerce?

Where CM Commerce Falls Short
Post-Purchase Marketing, Not Pre-Purchase Architecture
CM Commerce works after the checkout is complete. It does not change what happens before checkout - the browsing, cart building, and offer structure that determine order value.
No Bundle Builder or Cart-Level Offer Stack
CM Commerce sends receipt emails with product recommendations. It does not create tiered bundles, progressive rewards, or mix-and-match experiences that change the current order.
Receipt Email Revenue is Incremental, Not Primary
CM Commerce receipt emails generate 2-5% click-through rates. That is incremental revenue on the next order. Bundle architecture lifts the current order by 22-34%. The primary revenue lever is the cart, not the receipt.
Product Recommendations Without Bundle Context
CM Commerce recommends products in emails. Without bundle pricing context, those recommendations are single-product suggestions at full price. Bundle architecture adds the discount incentive to buy more.
