Abandoned cart recovery is the set of actions — mainly automated emails — that an online store uses to bring back shoppers who added products to their cart without completing the order. It is one of the highest-ROI levers in ecommerce, because it targets people who have already shown clear purchase intent.
To frame the opportunity: according to aggregated data from the Baymard Institute, the average cart abandonment rate in 2026 is about 70%. That means seven out of ten carts never become orders. Recovering even a fraction of them has a direct revenue impact.
Why people abandon their cart
The most frequent causes, again per Baymard, are about the checkout experience more than the product price:
- unexpected extra costs (shipping, taxes, fees) shown too late;
- forced account creation to complete the purchase;
- a checkout that is too long or complicated;
- doubts about returns, payment security or delivery times.
Understanding the cause matters because recovery is not just about "reminding" people of the cart: the email can address the objection (e.g. clarifying shipping costs) and lower the friction that blocked the purchase.
How a recovery flow works
A standard recovery flow triggers when an identifiable customer abandons the cart and sends a short message sequence:
- First reminder (within ~1 hour): light tone, recalls the products left in the cart.
- Second message (~24 hours): adds context — limited availability, reviews, answers to common objections.
- Third message (~72 hours): last chance, optionally with an incentive if your strategy allows it.
Optimal timing and the number of emails depend on the product type and margin. We go deeper in the dedicated guide on when to send recovery emails.
What makes a recovery email effective
The highest-recovering emails share a few traits: a clear, non-aggressive subject line, a visual reminder of the abandoned products, a single obvious call to action and copy that speaks to the reason for abandonment. We collected concrete examples and templates in cart recovery email examples.
Discounts: use them wisely
Offering a discount code is the most common shortcut, but it is not free: it cuts margin and, if used every time, teaches customers to abandon carts on purpose to get it. A prudent approach is to skip discounts in the first email, test them only in later messages, and measure their real effect on margin, not just on recovery rate.
The role of AI in recovery
The most demanding part of recovery is not setting up the flow, but writing and maintaining effective copy for every segment, product and language. This is where an AI-based system genuinely helps: AchillesAI generates subject and body variants for recovery emails, compares them and surfaces the ones that convert best, integrating with the email tools you already use. It does not replace your strategy — it makes it faster to execute and optimize.

In short
Abandoned cart recovery targets high-intent customers and, done well, is one of the highest-return activities in ecommerce. The basics: understand why people abandon, set up a 2-3 email sequence with the right timing, write copy that answers objections, and use discounts sparingly. AI helps most with the copy and continuous optimization.
