AI cart recovery

That sale

is still in

your cart.

// automated sequences that run while you sleep

Most stores recover 3 to 5% of abandoned carts with generic reminder emails. Our AI-written sequences recover 8 to 15% by sending the right message at the right time, specific to cart contents and customer history.

The problem

7/10

carts never reach checkout.

Seven out of ten carts never reach checkout.

They got distracted. They were comparison shopping. The shipping total surprised them. Their phone died. Most can be brought back with a well-timed message. Almost none are brought back by a single "did you forget something?" email 24 hours later.

The brands winning at cart recovery send 3 to 7 emails, timed around the psychology of purchase hesitation. First message in 15 minutes. Second at 24 hours. Third at 72 hours with an offer. Each one references the specific products in the cart.

Most stores don't run that. Most stores run one template. That gap is where the money is.

“The brands winning at recovery don't have better products — they have better follow-up. The window is 72 hours. Most stores miss it entirely.”

§ I — How the sequence runs

Four steps.
Runs without you.

STEP 01

Cart abandonment detected

Your store fires a webhook when a cart goes cold, within 15 minutes of no activity. We connect the integration once. After that it's automatic.

STEP 02

Sequence engine triggers

We select the right sequence variant based on cart value, product category, and whether we've seen this shopper before. No one-size-fits-all templates.

STEP 03

Emails go out on schedule

Step 1 at 15 minutes. Step 2 at 24 hours. Step 3 at 72 hours, with a conditional offer if we haven't heard back. All sent from your domain.

STEP 04

Purchase detected, sequence stops

The moment they buy, every remaining email stops automatically. No awkward reminders after they've already converted.

§ II — What you're actually buying

This is not “an abandoned cart email.”

It's a full software system: event tracking pipelines, session fingerprinting, transactional email infrastructure, conditional trigger logic, suppression lists, purchase-detection webhooks, sequence orchestration, delivery monitoring, and A/B variant routing. The AI is the brain that writes the right email for the right person at the right moment — it's one layer, the most important one, but not the whole product.

System layers, in order

Event & tracking layer

Cart webhooks, session fingerprinting, purchase-event listeners. Every action your shopper takes fires a signal — cart created, item added, checkout started, purchase completed.

Personalization intelligence · AI brainAI

Large language model analyzes cart contents, category, price point, and customer history to select and write the optimal message variant. This is where human-sounding copy comes from, at scale and on demand.

Email infra & deliverability

Sent from your domain over authenticated SMTP. SPF, DKIM, DMARC aligned. One-click unsubscribe, List-Unsubscribe headers, suppression on unsubscribe or purchase. Your domain reputation stays yours.

Monitoring & attribution

Open rates, click rates, and revenue attribution tracked weekly. Sequences adjusted when open or recovery rates drop. Monthly report shows actual dollars recovered — not "engagement" — tied to specific carts.

“Klaviyo gives you the pipes. We give you a system that's actually engineered — the right message for the right product at the right hesitation point, written by AI and tuned monthly against real recovery data. That's not the same thing.”

§ IV — Is your store a fit?

Not every store needs this.

this is right if you...

Have a real store with 500+ monthly visitors

Sell physical products with meaningful margins

Already have a sending domain and email list

Know your AOV and care about recovery rates

Want a set-it-and-forget-it revenue system

this is NOT right if you...

Sell digital downloads or subscription boxes (low abandonment)

Have under 200 monthly visitors (math doesn't work yet)

Have no email sending infrastructure at all

Want to see results in the first week (sequences take 4 to 6 weeks to season)

Need to approve every individual email before it sends

Questions worth asking

Things people actually ask before signing up

Shopify and WooCommerce natively. Any platform that fires a webhook on cart abandonment works: Magento, BigCommerce, custom builds. If it can send us an event, we can work with it.

Klaviyo gives you the pipes. We give you a system that's actually configured, written, and optimized. Most businesses set up one generic reminder and leave it. We run 3-to-7-step sequences with conditional discounts, dynamic copy, and ongoing performance tuning, all specific to your cart contents and customer history.

We send through your existing domain so emails come from your brand. Your domain reputation stays yours. We don't use shared IPs or generic platforms.

8 to 15% of abandoned carts, depending on brand recognition, discount strategy, and audience warmth. We'll give you a category-specific estimate before you commit. The low end is for cold audiences in competitive niches. The high end is for brands with strong name recognition and tight sequences.

The system detects the purchase in real time and suppresses all remaining emails immediately. No "you left something behind" messages after they've already bought.

Setup is straightforward on standard platforms. We absorb that cost and make it up on the monthly. If you have a heavily customized stack, there may be a small integration fee. We'll tell you before you commit.

// a note from casey

If you have carts, you have recoverable money.

The average store we work with recovers $4,000 to $18,000 in the first 90 days on the DFY plan. The setup is zero dollars. The sequences run without you touching them. The only question is how many carts you want to leave on the table.
