How does CART compare to TxtCart?

Both run two-way, AI-driven SMS conversations with shoppers. The difference is on the merchant side: CART is fully managed at every tier with no platform fee, charging per interaction only. TxtCart charges a platform fee from $29 to $399/month plus $0.99 per AI conversation resolution, and only offers a fully managed service as a separate $999/month add-on on top of that base plan.

How does CART compare to Postscript and Attentive?

Postscript and Attentive send one-way, templated SMS campaigns that merchants configure and manage themselves. CART opens a real two-way conversation with each shopper and is fully managed end-to-end, with no dashboard to run and no platform fee, charged per interaction only.

Does CART replace Klaviyo?

No. CART runs alongside Klaviyo rather than replacing it. Klaviyo owns email and campaign SMS, and its Customer Agent answers shopper support questions. CART owns cart-recovery conversations specifically, adding an incremental recovery layer on top of what Klaviyo already does.

Is CART a fit for every Shopify store?

No. CART is built for Shopify Advanced and Plus stores, or stores on other platforms with meaningful cart volume, US-based shoppers, and merchants who want a managed service rather than a self-serve dashboard. It's not the right fit for stores on lower Shopify tiers, stores with very low cart volume, primarily international shopper bases, or teams who want to write and send every message themselves.

Do I need to connect my store for customer winback?

Not for the first round. You can start from a customer file or Klaviyo export, with no store connection and no setup fee. Ongoing winback triggers run on a live feed of your order data, such as your store, Klaviyo, an API or a webhook, and the one-time setup fee applies at that point.

How many customers do I need for CART Customer Winback?

At least 5,000 customers who opted in to texts and last ordered 4 to 24 months ago. That is enough for a meaningful first round. Winback works on any ecommerce platform.

CART vs Attentive, Postscript, TxtCart & More

Q: I already use Postscript, Attentive, or another SMS tool for cart recovery. Does CART conflict with it?

During the trial, CART pauses the cart-recovery-specific flow in your existing SMS tool, so there's no overlap or duplicate messaging to the same shopper. Everything else on your SMS program – welcome series, campaigns, non-cart flows – keeps running as normal.

	CART	Attentive	Postscript	TxtCart	Recart	LiveRecover
Cost structure	No platform fee. Credits per message, plus a one-time setup fee	Platform fee + usage (custom contract)	Platform fee + per-message	Platform fee + per-message + AI resolution fee	Platform fee + SMS credits (quarterly commitment)	Platform fee + share of recovered revenue
Pricing range	$0.20 per credit, dropping to $0.14 on larger packs, plus a one-time $500 setup fee for the first engine that connects	No public pricing	$49–$500+/mo (self-serve) + per message; AI plan (includes Shopper) +$699/mo	$29–$499/mo + per message + $0.99/resolution	$500+/mo for SMS (entry plan includes about 41,700 messages), quarterly commitment, + carrier fees	$199/mo + 10% of recovered revenue, or $499/mo + 5%
Phone number	10DLC	10DLC, Toll-Free, or Short Code (by business size)	Dedicated Toll-Free	Toll-Free (Dedicated Short Code +$1,500/mo add-on)	Not published	Dedicated number (type not published)
Shopper conversation	Two-way, AI agent that we run for you	Templated flows plus two-way AI (Concierge) you configure	Templated flows plus two-way AI (Shopper) you configure	Two-way, AI agent you configure	Automated flows; no conversational AI	Live human agents plus automated SMS; no AI agent
Merchant experience	Fully managed at every tier	Self-serve platform; onboarding and a support team included	Self-serve; dedicated CSM at Enterprise; Postscript Plus managed service available (custom pricing)	Self-serve; managed service from $999/mo (included in Enterprise)	Self-serve on the entry plan; no success manager or managed SMS	Live agents included on both plans

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

Attentive, Postscript and Recart require you to configure and run your own program. TxtCart's self-serve AI still requires setup and ongoing management, and LiveRecover relies on human agents who take a share of your recovered revenue. CART is the only one that pairs a two-way AI agent with a fully managed service 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, and its Customer Agent answers shopper support questions, billed per resolution (about $0.70 in Klaviyo's own ROI calculator). CART owns cart-recovery conversations. Different job, same stack.

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

During your free trial, 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...

You're on Shopify but not on the Advanced or Plus plan – CART is built specifically for the checkout infrastructure on those plans. If you're on another platform, you qualify on monthly cart volume instead.
You get very few abandoned carts each month – the free trial costs nothing, 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.

Winback texts the customers who bought once and went quiet. The other tools run it as a flow you build. CART runs it as a conversation, and you can start from a file you already have. It works on any ecommerce platform.

	CART	Klaviyo	Attentive	Postscript	TxtCart
Cost structure	No platform fee. Credits per message. No setup fee for the first round from a file	Platform plan by profiles + SMS usage	Platform fee + usage (custom contract)	Platform fee + per-message	Platform fee + per-message
Pricing range	$0.20 per credit, dropping to $0.14 on larger packs. No setup fee for the first round from a file; the one-time setup fee applies when a live order feed connects	No winback-specific pricing published	No public pricing	$49–$500+/mo (self-serve) + per message	$29–$499/mo + per message
What you start from	First round: a customer file or Klaviyo export, no store connection. Ongoing: a live feed of your order data	Klaviyo profiles and purchase data	Attentive subscribers and purchase data	Postscript subscribers and order data	TxtCart subscribers and purchase history
How it picks who to text	First round: customers grouped by last order and time quiet. Once connected: four ongoing triggers	An inactivity window you set, such as 60 days since last purchase	AI picks likely lapsers, up to 1% of subscribers a day	A timed automation you build	A trigger you set, such as 60 days since last order
Customer conversation	Two-way, picks up from what they last bought	Templated email, then SMS or RCS. No conversational AI published	Templated texts with an offer you add	Templated multi-step texts with a discount code	Templated flows with AI personalization and reply handling
Merchant experience	Fully managed at every tier	Self-serve; you build and run it	Self-serve; you write the copy and set the offer	Self-serve; you build it in the dashboard	Self-serve; managed service from $999/mo (included in Enterprise)

A flow you build, or a conversation we run.

Klaviyo, Attentive, Postscript and TxtCart run winback as a timed flow you build and tune, usually with a discount in the message. CART runs it as a two-way conversation that picks up from what the customer last bought, and we run it for you.

Already using Klaviyo?

CART doesn't replace it, it runs alongside it. For a first round, send us a Klaviyo export and we run the conversation. Your own email and SMS flows keep running as normal.

Already running a winback flow in Postscript, Attentive, or TxtCart?

CART texts customers who have gone quiet, so it doesn't overlap with your active flows. Everything you have running keeps running as normal.

Winback Isn't a Fit If...

You have fewer than about 5,000 customers who opted in to texts and last ordered 4 to 24 months ago – that's too small a group for a meaningful round.
Most of your customers last ordered more than 24 months ago – the relationship has usually gone cold by then.
You can't show opt-in consent – no consent evidence, no send.
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 customers are mostly outside the US – CART runs on US carrier infrastructure only, no overseas SMS relay.
