How Shopify Brands Can Recover Abandoned Carts With SMS in 2026
Features and prices taken from Signal House's website and Shopify App Store listing, November 2026.
An abandoned checkout is the highest-intent moment in your store. The shopper picked a product, entered their details and stopped one step short of paying. Most stores answer that moment with a single email that sits unopened. A text message lands on the phone they just used to shop, with a link straight back to their cart.
Signal House is a Shopify app built for exactly that. It texts shoppers who abandon checkout, links them back to their cart, handles their replies and keeps you compliant with US texting rules, without a developer or a seven-figure price tag. Here is how it works and what it costs.
What the Signal House Shopify app does
Automatic cart recovery texts. When a shopper leaves checkout without buying, the app sends a timely text that links them straight back to their Shopify checkout. You can add a discount code to win back more sales.
Two-way conversations with AI-assisted replies. When customers text back with a question, Signal House answers in your brand voice. Every thread shows up in a live inbox, and you can take over any conversation whenever you want.
Broadcast campaigns. Send texts to opted-in customer segments, schedule them ahead of time and start from templates. Welcome messages and win-back campaigns are built in.
Recovered revenue tracking. One dashboard shows the revenue your texts brought back and how your SMS subscriber list is growing.
SMS and MMS. Send plain text or picture messages with product images.
Set it up once, without a developer
There is no developer, no Twilio account and no 40-page onboarding document. You install the app, connect your number and turn on cart recovery. From there it runs on its own, and you step in only when a conversation needs you.
Compliance is handled for you
Texting customers in the US means registering your business and your campaigns with the carriers (10DLC registration), collecting consent and honoring opt-outs. Get any of it wrong and your texts get blocked. Signal House builds it in:
10DLC brand and campaign registration, with approval in as little as 48 hours
Opt-in collection
Quiet hours, so customers aren't texted at the wrong time
Automatic STOP and HELP handling
Texts that actually arrive
A recovery text only works if it is delivered. Signal House sends through direct connections with carriers and carrier partners, with delivery rates above 95% and near-instant SMS and MMS. And when something does go wrong, real people answer in real time instead of a ticket queue.
What it costs
The app is free to install, with no contract and no minimum. Pricing on the Shopify App Store:
| Plan | Monthly price | SMS segments included | Extra segments |
|---|---|---|---|
| Free | $0 | 100 | $0.009 per SMS, $0.027 per MMS |
| Starter | $29 | 3,850 | $0.0075 |
| Growth | $79 | 12,150 | $0.0065 |
| Scale | $199 | 36,150 | $0.0055 |
10DLC registration is a one-time $5 per brand and $15 per campaign. Charges are billed every 30 days. New Signal House accounts also get $25 in free credit, which covers their first brand, campaign, numbers and messages.
That pricing is built for stores at every stage. Many SMS tools are priced for brands already doing seven figures; Signal House lets a store test cart recovery on its next abandoned checkout before paying anything.
