CartRocket is a Shopify app for pre-loaded cart links. A merchant selects products, variants, quantities, discounts, bundle pricing, access rules, purchase limits, and tracking; CartRocket generates one shareable link that opens a prepared cart or routes the shopper toward checkout.

What a CartRocket preset contains
A preset is a reusable campaign configuration. It can include selected products and variants, quantities, line-item or cart discounts, shipping incentives, discount codes, customer eligibility, overall or per-customer purchase limits, active dates, and UTM or custom tracking parameters.
How it works
- Create a preset in the CartRocket dashboard.
- Add the exact products, variants, and quantities promised by the campaign.
- Configure discounts, eligibility, limits, and active dates.
- Choose whether the link opens cart, checkout, or Shop Pay.
- Add campaign parameters and publish the link in ads, email, SMS, or creator content.
- Review orders, revenue, and AOV for the preset.
Where pre-loaded cart links perform best
- Email and SMS: send a known customer back to a replenishment set or time-limited bundle.
- Creator campaigns: give each creator a trackable link to the exact promoted kit.
- Paid retargeting: shorten the path for shoppers who already viewed the offer.
- VIP drops: restrict a preset to a Shopify customer segment and cap purchases.
- QR codes: connect packaging, events, or printed cards to a mobile-ready cart.
Cart, checkout, or Shop Pay?
| Destination | Use it when | Tradeoff |
|---|---|---|
| Cart | The shopper should inspect a bundle or edit quantities | Adds a step, but provides context |
| Checkout | The audience is high intent and the offer is fully explained | Fastest path; poor fit for cold traffic |
| Shop Pay | Mobile speed and returning-Shopper convenience matter | Depends on shopper and store setup |
How CartRocket and Smart Checkout Widgets work together
The products solve adjacent stages. CartRocket controls the campaign link and arrives with the right cart. Smart Checkout Widgets controls what eligible Shopify Plus shoppers see in checkout: automatic or customer-choice gifts, upsells, BOGO offers, banners, trust content, custom fields, and payment presentation.
A practical flow is: creator link → pre-loaded bundle and discount → Shopify checkout → eligible gift or complementary upsell → concise trust message → payment. Keep one system of record for promotion rules and test the combined flow so a preset discount does not conflict with checkout eligibility.
Campaign example: a BFCM creator bundle
- Create a three-product preset named for the creator and campaign.
- Apply the advertised line-item discount and set the BFCM date window.
- Add creator-specific UTM parameters.
- Route to cart if shoppers need to review variants; otherwise test checkout routing.
- In Smart Checkout Widgets, show one threshold gift only if the discounted subtotal remains eligible.
- Place a short shipping cutoff or returns message near payment.
- Run a full mobile test order, then verify attribution and margin.
Common mistakes
- Sending cold traffic directly to checkout without enough product context.
- Promising a variant that is unavailable or likely to sell out.
- Stacking preset and checkout discounts without a written precedence rule.
- Using one generic link for every creator, channel, and audience.
- Measuring revenue without subtracting discounts, gift cost, returns, and creator fees.
When not to use a direct cart link
Do not skip the product page when the item needs education, sizing guidance, comparison, regulatory context, or significant trust building. A faster route is only better after the shopper has enough information to make the decision.
Next step
Build one preset for a proven offer, publish it to a single channel, and compare conversion rate, AOV, and contribution margin with the normal landing path. See CartRocket for the product overview or use the documentation for setup details.
