We build AI-powered SMS and email systems that recover abandoned carts within 15 minutes, convert one-time buyers into repeat customers through post-purchase sequences, and identify at-risk customers before they churn — turning your existing traffic and customer base into a compounding revenue engine without spending more on ads.
The average eCommerce store loses 70 cents of every dollar of intent it generates. Someone lands on your site, finds something they want, adds it to their cart — and then life interrupts. The phone rings. A notification pulls them away. They think "I'll come back later." Later never comes. Without an AI-powered recovery system that follows up within 15 minutes via SMS and again at 4 hours and 24 hours, that purchase is gone. Multiply that by every cart abandoned across a year, every one-time buyer who never ordered again, every repeat buyer you lost to a competitor — and the average eCommerce business is leaving $96,000 a year on the table.
Most abandoned cart emails go out 1–2 hours after the cart is left. By then the buying moment has passed — the person is watching TV or in a meeting. SMS recovery sent within 15 minutes catches buyers while the intent is still hot. A three-touch sequence — 15 minutes, 4 hours, 24 hours — with a small incentive on the final touch recovers 30–40% of abandoned carts. Without it, you're gifting that revenue to your competitors' retargeting ads.
Someone buys for the first time. They get an order confirmation and a shipping notification. That's it. No welcome message. No product usage tips. No follow-up asking how they're going. No prompt to reorder when they're likely running low. No cross-sell for the complementary product. Six months later they're a lapsed customer who never felt any reason to come back. The most valuable thing you can do with an existing customer is make them a second-time buyer — and that window opens in the first 30 days.
A customer who's ordered 4 times in the last 12 months goes 90 days without ordering. No one notices. No one reaches out. They've either found a competitor, had a bad experience that wasn't resolved, or simply drifted. A win-back sequence triggered by purchase gap — "we haven't seen you in a while, here's 10% off your next order" — reactivates 20–35% of lapsed customers at a fraction of the cost of acquiring a new one. These are your most valuable customers and the easiest to recover.
A shopper on your site at 9pm has a question about sizing, shipping, or a product detail. There's no one to answer it. They leave and buy from a competitor with a live chat. An AI that handles product FAQs, shipping questions, returns policy, and size guidance in real-time — and escalates anything it can't resolve — removes the last friction point between a browser and a buyer, around the clock.
Every Supersonic engagement starts with your store's biggest revenue leak — not a generic tech stack. We scope, build, and guarantee the outcome. The first system is live within 72 hours of onboarding.
Abandoned carts trigger a three-touch recovery sequence via SMS — 15 minutes, 4 hours, and 24 hours after abandonment. The 15-minute touch catches the buyer while intent is still high. The 4-hour touch addresses likely objections — size, shipping, returns policy. The 24-hour touch includes a time-limited offer to close undecided buyers. Each message is personalised to the specific product left behind. Stores running this system recover 38% of abandoned carts on average — compared to an industry average of 8–12% for email-only sequences.
Every first-time buyer enters a 30-day post-purchase sequence — product tips and care advice on day 3, a cross-sell or complementary product prompt at day 14, and a reorder or new collection preview at day 30. Returning customers get a loyalty acknowledgement and early access to new products or sales. The second purchase is the most important conversion in eCommerce — customers who buy twice are 5× more likely to buy a third time. Stores running this system see 54% more repeat orders within 90 days of implementation.
Purchase gap monitoring flags customers who are overdue for a reorder based on their individual buying cadence. High-value customers who haven't ordered in 60 days get an early win-back touch. The full lapse sequence fires at 90, 97, and 104 days — each with escalating urgency and a time-limited incentive. Separately, customers who show browse-but-not-buy behaviour on the site trigger a re-engagement message within 24 hours. Stores running this system reactivate 25% of lapsed customers who would otherwise have been permanently lost.
An AI chat layer on your store handles product questions, sizing guidance, shipping timelines, and returns policy 24/7 — removing the final friction point between a browser and a buyer at every hour of the day. Post-delivery, your system fires a personalised review request at the peak satisfaction moment — 3 days after confirmed delivery. Customers who just received something they love are the most likely reviewers anywhere. Review volume directly lifts your store's conversion rate for new visitors and your Google ranking for local and branded searches.
Watch how your AI recovers an abandoned cart from someone who got distracted mid-checkout — answering a returns question in real time, sending them back to their cart, and closing the sale in under 10 minutes. This runs automatically every time a cart is abandoned, day or night, without anyone on your team being involved.
Before: a single email went out 2 hours after abandonment, recovering around 7% of carts. After: a three-touch SMS sequence — 15 minutes, 4 hours, 24 hours — with product-specific messaging and a 10% incentive on the final touch. In month one, 38% of abandoned carts were recovered. Total recovered revenue: $14,200. The 15-minute SMS alone accounted for 61% of all recoveries — buyers were still on their phone when the message arrived and clicked straight back to checkout.
Before: first-time buyers received no follow-up beyond shipping notifications. 18% of first-time buyers made a second purchase within 90 days. After: a 30-day post-purchase sequence with product tips, cross-sell prompts, and a replenishment reminder at day 25. Second purchase rate went from 18% to 41% within 60 days of launch. Average order value of second purchases was 34% higher than first purchases — because the sequence introduced complementary products the customer didn't know existed.
A win-back sequence sent to 2,200 customers who hadn't ordered in 90+ days generated a 31% reactivation rate. 682 customers placed a new order within the 14-day campaign window. Average order value: $56. Total recovered revenue: $38,192. The entire campaign cost nothing to run and required zero manual work. The brand had been spending $8,000/month on paid acquisition to find new customers — this campaign recovered more revenue in two weeks than a month of ads, from customers already in the database.
Generic automation tools aren't built for eCommerce retention. They don't understand the difference between a first-time buyer who needs nurturing and a lapsed VIP who needs reactivating, why timing is everything in cart recovery, or how to write a post-purchase message that feels personal rather than automated. We do — because we've built specifically for online stores.
Not a prototype. Not a demo. A working cart recovery and post-purchase system running on your real store — within 72 hours of onboarding. You see results before your second invoice.
We understand buying cadence, cart abandonment psychology, cross-sell timing, and why the 15-minute SMS window beats a 2-hour email every time. Scripts and sequences are built for how online shoppers actually behave.
No patchwork of third-party tools, no Klaviyo-plus-Attentive-plus-Gorgias integrations. Your entire retention stack runs inside a purpose-built system we own and control — faster builds, tighter reliability, zero platform risk.
Month-to-month, cancel any time. We don't lock you in — we earn your business every month. Your dedicated CRM tracks every lead, every conversion, and every dollar recovered so you always see exactly what you're getting.
Our systems are SOC II Type 2 certified and built to meet enterprise security standards. Your customer data is handled exclusively within our certified infrastructure — never stored in third-party tools or shared platforms. Full data processing agreements available on request.
Our agents are built with strict conversation guardrails. They handle product questions, cart recovery, and support — and hand off anything outside their scope immediately. Your AI never says something it shouldn't.
If the agreed performance metric isn't hit within 90 days, we keep working at no charge. No agency that lacks confidence in their work for eCommerce stores can afford to make that offer.
We stake our fee on your results. If the systems we build don't deliver the agreed improvement in cart recovery and repeat purchase rate within 90 days, we keep working at no charge until they do. No asterisks. No fine print.
This is a guarantee no agency that lacks confidence in their work for eCommerce stores can afford to make. We make it because our systems — built specifically for how online shoppers behave — work. Every time.
"We will recover 38% of abandoned carts within 90 days — or we keep building until we do, at no additional charge."
"We were sending one email 2 hours after cart abandonment and recovering about 7%. The SMS sequence changed everything — the 15-minute text catches people while they're still on their phone. We're now recovering 38% of abandoned carts and it generated over $14,000 in month one alone."
"Our repeat purchase rate was 18% — totally typical, apparently, but still frustrating when you're paying $40 to acquire each customer. The post-purchase sequences moved it to 41% in 60 days. The average second-order value was also 34% higher because the cross-sell actually worked."
"We had 2,200 lapsed customers we'd essentially written off. The win-back campaign reactivated 682 of them in two weeks — $38,000 in revenue from a list we weren't even touching. That's more than a month of paid acquisition spend, for free."
"Before Supersonic, our customer lifetime value was basically one order and done. Now we have cart recovery running, a full post-purchase sequence, and win-back flows for lapsed customers. CLV is up 71% in 6 months. We're spending the same on ads but making 71% more per customer — which means our ROAS has effectively doubled without touching a single campaign."
We've heard every objection. Here's exactly what we say — no vague answers, no redirects.
Your abandoned cart recovery system is live within 72 hours of onboarding. Most stores see their first recovered carts within hours of going live — typically from overnight abandonment events that would otherwise never have been followed up.
Yes — we integrate with Shopify, WooCommerce, BigCommerce, and Magento. Cart data, customer purchase history, and order status flow directly into our system. Your store operates exactly as it does today — we layer on top without disrupting your existing setup.
No — every message references the specific product the customer left behind, uses a conversational tone, and provides genuine value (answering questions, offering help). Our recovery messages read like a helpful team member reaching out, not a bulk SMS blast. Opt-out rates on our sequences are consistently below 1%.
It can complement it or replace it — depending on your setup. We've built systems that run alongside Klaviyo (adding SMS recovery to email flows) and full replacements that consolidate everything into our system. We'll scope what makes most sense for your store on the strategy call — no unnecessary disruption to what's already working.
Supersonic is $4,000/month. That covers your full cart recovery, retention, and win-back system, built and managed for your store. Most stores recover the investment from additional cart revenue alone in the first month. We'll confirm everything on your strategy call.
No problem — our system pulls the specific product name, image, and details from the abandoned cart dynamically. Every recovery message is personalised to the exact item. Stores with large catalogues typically see the strongest results because specific product references dramatically outperform generic "you left something behind" messages.
The 3-minute AI Readiness Quiz tells us exactly where your store is leaking revenue — abandoned carts, one-time buyers, lapsed customers — and what to automate first. Qualified stores get a free 30-minute strategy call where we map the exact system we'd build.
