How CART Compares

CART vs Attentive, Postscript, and TxtCart

Here's how they actually differ on cost, conversation type, and who's running the program.

Enterprise software or run it yourself. There's no third option, until now.

Attentive and Postscript both require you to configure and run your own program. TxtCart's self-serve AI still requires setup and ongoing management. CART is the only one of the four that's fully managed at every tier, no dashboard to run.

Already using Klaviyo?

CART doesn't replace it, it runs alongside it. Klaviyo owns your email and campaign SMS. CART owns cart-recovery conversations. Different job, same stack.

Already running Postscript, Attentive, or another SMS tool for cart recovery?

During your Revenue Proof, we pause just the cart-recovery-specific flow in your existing SMS tool, so there's no overlap or duplicate messaging to the same shopper. Everything else – welcome series, campaigns, non-cart flows – keeps running as normal. See our architecture breakdown for more on how CART is built.

CART Isn't a Fit If...

  • Your store isn't on Shopify Plus or Advanced – CART is built specifically for that tier's checkout infrastructure.
  • You get very few abandoned carts each month – the Revenue Proof trial still runs free, but the incremental lift will be small in absolute terms.
  • You want to write and send every message yourself – CART is a managed service. You approve the strategy; we run execution day to day.
  • Your shoppers are mostly outside the US – CART runs on US carrier infrastructure only, no overseas SMS relay.
