Cart recovery: WhatsApp, SMS, or email?

Most of the carts your store builds never check out. Cart abandonment across ecommerce runs high everywhere, often 70 percent or more. That means the single biggest pile of nearly won sales you have is not new traffic. It is the people who already picked something and then walked away. The question is how to tap them on the shoulder.

You have three tools, and they are not equal. Email is nearly free to send and gets opened 15 to 25 percent of the time. A text gets opened almost always, close to 98 percent, and costs a few cents. WhatsApp, where it is common, gets read almost every time too, and it feels more like a conversation than a broadcast.

Where you sell decides the winner. In India, WhatsApp is the channel people actually live in, and published playbooks report WhatsApp recovery flows winning back 15 to 25 percent of abandoned carts against 5 to 8 percent for email. In the US, WhatsApp is rare for shopping, so the pairing that works is a text for urgency and an email for depth, with cart texts recovering a meaningfully larger share than email on its own.

The mistake is to run the same reminder on every channel and hope. A good recovery message is timely and specific: it shows the exact item, it goes out while the intent is still warm, and it stops the moment the person buys or clearly says no. One thoughtful nudge beats five nags, on any channel.

So do not ask which channel is best in the abstract. Ask where your customer reads. Sell in India and WhatsApp is very likely your highest return recovery channel. Sell in the US and it is text plus email working together. Either way, the carts are already there, already chosen. Recovering even a slice of them is the cheapest revenue in the store.
