The verdict in three sentences
Across West and East Africa, WhatsApp beats email for recovering abandoned carts. In Niamey, an SMS + WhatsApp sequence recovers 18% of carts versus 6% for email. The secret: the right timing and a mobile-money payment link embedded directly in the message.
The channel decides everything
An unread email recovers nothing. A WhatsApp message with the product, price and a payment link is read within minutes. Channel choice matters more than message copy.
| Channel | Open rate | Cart recovery | Cost per message |
|---|---|---|---|
| 21% | 6% | ~1 FCFA | |
| SMS | 94% | 12% | 25 FCFA |
| 98% | 18% | 8 FCFA | |
| WhatsApp + pay link | 98% | 21% | 8 FCFA |
| Manual call | 70% | 15% | agent time |
In Kigali, a WhatsApp click-to-pay MoMo link recovers 21% of carts: the customer pays without leaving the conversation.
The timing of the sequence
Follow up too late and you lose the customer; too early and you annoy them. A three-step sequence, with an incentive reserved for the last message, maximises recovery.
| Send | Delay after abandon | Message | Incentive |
|---|---|---|---|
| 1st reminder | 1 hour | "Your cart is waiting" | none |
| 2nd reminder | 24 hours | "Limited stock" + pay link | none |
| 3rd reminder | 72 hours | "-5% today" | 5% code |
| Close | 7 days | final reminder | 5% code |
The 5% code on the third send adds about 4 recovery points without eroding margin on customers who would have converted without a discount.

Mini case study
Eric, who runs an electronics shop in Kigali, records 500 abandoned carts a month. With email alone he recovered 6%, i.e. 30 sales. Switching to an SMS + WhatsApp sequence with a payment link, he recovers 21% via click-to-pay: 105 sales, i.e. 75 more. At RWF 45,000 per cart, that is substantial monthly revenue recovered for a messaging cost of a few thousand francs.
FAQ
Is WhatsApp really better than email? Yes. In Niamey, WhatsApp recovers 18% of carts versus 6% for email, with a 98% open rate versus 21%.
When should I send the first reminder? One hour after abandonment, while the product is fresh. Then follow up at 24h and 72h.
Should I offer a discount in every message? No. Reserve the -5% code for the third reminder only, to avoid eroding margin on customers ready to pay without a discount.
Is SMS worth its 25 FCFA? It recovers 12% of carts, more than email. But WhatsApp does better at 8 FCFA: combine both.
Is the click-to-pay link hard to set up? No. A mobile-money link inside the WhatsApp message enables one-tap payment; in Kigali it recovers 21% of carts.
