WhatsApp abandoned-cart recovery works when the shopper already had intent. Items in the cart, checkout started. A timely, useful message brings them back. It is a nudge to a warm buyer, not a rescue for a broken offer or a cold list.
Done properly, it means a message sent a short while after the cart is abandoned, on the channel Indians actually read, showing the product with a way to finish the purchase. It runs on the WhatsApp Business API with Meta's per-conversation fees, not on free broadcasts.
How the recovery flow actually runs
The trigger is a cart with a started-but-unfinished checkout. After a short wait, the agent sends a message in the category Meta's rules require, shows the item left behind, and gives a one-tap way back to checkout. A second, lighter nudge sometimes follows. The flow stops the moment the shopper buys or opts out.
The part that makes or breaks it is the wiring. The agent has to read your store's real cart and order data, so it knows what was abandoned and whether it has since been bought. Otherwise you message people who already paid. It also needs the shopper to have opted in, and the templates approved.
The numbers you will be shown, read honestly
AiSensy publicly reports that for the Indian D2C brand The Hatke, WhatsApp automation delivered 21× ROI and recovered 40% of abandoned carts. Those are AiSensy's reported results for its client. A single store, and a headline to treat as the vendor's claim rather than a forecast for you. The open rate is the believable core: WhatsApp genuinely gets read where email does not.
The useful question is not "can I get 21×." It is: what is my current cart-recovery rate, and what does one recovered order earn me after Meta's conversation fee? A lift measured against doing nothing is not the same as a lift measured against the email flow you already run.
The costs that never make the screenshot
A recovered cart is not free to chase. Meta charges per conversation, and the category moves the rate. On top sits your platform fee, where margin quietly leaks. A per-message markup looks tiny until you multiply by real volume. Then there is the build itself, priced once.
The real economics are the recovered order's margin minus the conversation fee, the platform cut, and the build. On a healthy-margin product with warm carts, that clears easily. On a thin-margin item chased with a marketing-category message every time, the fee can eat the recovery.
When cart recovery is the wrong spend
When you do not have the cart volume to begin with. A handful of abandonments a day does not repay a build.
When the offer or the price is the reason people leave. Automation makes the nudge instant and relentless. If the underlying offer is wrong, you have automated the speed at which shoppers decline.
When you have no opted-in base and are tempted to blast a cold list. That fails twice: the conversion is near zero, and Meta's quality rating drops, which throttles your legitimate messages too.
When your cart and order data are not clean enough to know who abandoned and who already bought. The data is the prerequisite, not a detail.
