The Right Message at the Right Moment
Say something meaningful next to every product in the cart. Line messages attach targeted, contextual copy directly under individual line items — exactly when shoppers are reviewing and deciding whether to check out.
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 in context, next to the item it's about — making it far more relevant and much harder to miss.
- Message appears below the line item inside the cart drawer
- Each product can display its own message based on campaign rules
- Multiple campaigns can attach messages to the same product at the same time
- Supports any HTML content, including styled text, links, icons, and emojis
What to Use It For
Line messages are flexible enough to serve a wide range of use cases. Use them to reinforce value, drive urgency, cross-sell, or manage expectations — all in the most high-intent moment of the shopping journey.
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.
- A message only appears when its trigger product is in the cart
- Layer on customer tags, login status, Shopify market, or cart conditions
- Schedule messages to run during specific date ranges
- Run multiple line message campaigns simultaneously across different products
Everything you need to add context to every cart item
Full targeting, per product

Flexible and precise

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.
