The Right Message at the Right Moment
Put a short message right under any product in the cart. Line messages show up while shoppers are reviewing their order and deciding whether to check out, which is exactly when a nudge lands best.
Attached to the product, not the cart
Attached to the Product, Not the Cart
Unlike announcement bars or cart-level messaging, line messages sit directly beneath the specific product that triggered them. Shoppers see the message next to the item it's about, so it's relevant and hard to miss.
What to Use It For
Use line messages to reassure, cross-sell, or set expectations. Whatever the message, it reaches shoppers at the moment they're deciding whether to buy.
Campaign-Powered Targeting
Line messages are campaigns, so they inherit CornerCart's full targeting and scheduling system. Messages are tied to the product that triggers them, not applied globally to every cart.
Everything you need to add context to every cart item
Highlight Product Benefits
Reinforce why a product belongs in the cart right before checkout.
Put a key stat, a guarantee, or a quality signal right next to the item, at the point where shoppers want reassurance.
Showcase Promotions
Call out a time-sensitive offer tied to that specific product.
Like a bundle discount, a seasonal deal, or a limited-time price break. The message sits right next to the item it applies to, making it impossible to miss.
Cross-Sell Complementary Products
Nudge customers to add a related product with a direct link or incentive.
Show "Add the matching serum for 20% off" next to the moisturizer already in their cart. The context does most of the selling for you.
Communicate Purchase Limits
Display quantity caps or urgency cues directly on the affected product.
During flash sales or low-stock events, show "Limit 2 per order" or "Only a few left" right next to the item instead of buried in a generic cart banner.
Campaign-Powered Targeting
Messages are tied to the product that triggers them, not applied globally.
Line messages inherit CornerCart's full targeting and scheduling system. Layer on additional conditions to reach the right shoppers at the right time.
Full targeting, per product
Every line message is a campaign. You decide who sees what, when it runs, and which product triggers it.
Flexible and precise
You control exactly what shoppers see next to each product in their cart, down to the individual item.
Want to see it in action? Book a call with usMultiple line message campaigns can target the same product and will stack one below the other. Run a benefit highlight and a promotion message on the same item at the same time.
Line messages support full HTML, so you're not limited to plain text. Include links, icons, formatted text, emojis, and any inline styling that matches your brand.
Frequently asked questions
Everything you need to know about cart line messages.
Where does the message appear?
Directly below the line item inside the cart drawer. It's rendered in context with the product it's about, not as a separate cart-level banner.
What kind of content can I put in a line message?
Line messages support HTML, including styled text, inline links, icons, and emojis. You have full control over how the message looks alongside the product.
Which products show a message?
Only products that match the campaign's trigger conditions. If a campaign is set up for a specific product, the message appears only when that product is in the cart.
Can the same product show more than one message?
Yes. Multiple line message campaigns can target the same product and will stack one below the other.
Can messages include dynamic cart data, like "add $X more for free shipping"?
Not currently. Line messages are static HTML content. For dynamic threshold messaging, use the progress bar feature instead.
Can I target line messages to specific customers?
Yes. Since line messages are campaigns, you can layer additional targeting on top of the product trigger, including customer tag (if logged in), Shopify market, or other cart conditions.
