Pay-As-You-Go SMS Cart Recovery
Looking for a Postscript alternative? CartBoss recovers abandoned carts without monthly subscriptions or per-contact charges. Pay only for messages sent — and it works on both Shopify and WooCommerce.
CartBoss vs Postscript at a Glance
Both tools send SMS messages, but the pricing and scope are very different. CartBoss is built for abandoned cart recovery with pure pay-as-you-go pricing — Postscript is a broader SMS marketing platform with subscription fees.
CartBoss
-
Pure pay-as-you-go — no monthly subscription, no tiers, no contact-list charges. You only pay for SMS messages actually sent.
-
Shopify + WooCommerce — works with both major e-commerce platforms. Run stores on different systems without switching tools.
-
Instant setup, no campaigns to build — install the app and cart recovery starts immediately with pre-optimized SMS sequences.
-
Transparent per-message pricing — know exactly what each message costs upfront. No credit bundles, no hidden overage fees.
-
Cart recovery specialist — every feature is optimized for recovering abandoned carts. No feature bloat from campaigns, segments, or list management.
Postscript
-
Monthly subscription from $25/mo — you pay a platform fee every month even before sending a single message. Per-message charges are added on top.
-
Shopify only — Postscript is built exclusively for Shopify. WooCommerce, BigCommerce, and other platforms are not supported.
-
Campaigns, segments, and automations to configure — before sending cart recovery messages, you need to set up subscriber lists, segments, and automation workflows.
-
Credit-based messaging costs — message pricing uses a credit system that can be confusing. Costs vary by message length, MMS, and carrier fees.
-
Broad SMS marketing scope — Postscript covers campaigns, sales alerts, loyalty programs, and more. Cart recovery is just one of many use cases, not the primary focus.
Why Stores Switch to CartBoss
Postscript is a capable SMS marketing platform, but if your main goal is recovering abandoned carts, you're paying for features you don't need. CartBoss gives you exactly what matters — at a fraction of the cost. Check our pay-as-you-go pricing.
No Subscription Tax
Stop paying a monthly fee before you even send a single message. CartBoss charges per SMS sent — nothing more. Your costs scale directly with the revenue you recover.
Multi-Platform Support
CartBoss works with both Shopify and WooCommerce. Unlike Postscript, you're not locked into a single e-commerce platform — perfect if you run multiple stores or plan to migrate.
Predictable Costs
No credit bundles, no tier upgrades, no surprises. CartBoss shows you a clear per-message price for each country. You always know what you'll pay before you send.
Cart Recovery Without the Overhead
Postscript is a full SMS marketing platform. It handles subscriber collection, campaign broadcasts, sales alerts, conversational commerce, and automation workflows. If you need all of that, it can be a solid choice — but it comes with a monthly subscription and a setup process that takes hours, not minutes.
For store owners whose primary goal is recovering abandoned carts, CartBoss eliminates the overhead. There's no subscriber list to build — CartBoss captures phone numbers from the checkout process. There are no campaigns to design — recovery messages are pre-written and optimized. There's no automation to configure — everything works the moment you install the app.
The pricing difference is significant too. Postscript charges a monthly platform fee plus per-message costs. CartBoss charges per message only — no subscription, no tiers, no minimum spend. For a store that sends a few hundred recovery messages per month, that difference adds up quickly.
