The verdict in three sentences
In Ghana, Senegal and Cote d'Ivoire, 70 to 80% of carts are abandoned, and email is not the right channel: it opens at just 20% versus 98% for SMS and massive read rates on WhatsApp. A reminder within 1h alone recovers about 10% of carts; a 1h / 24h / 72h sequence climbs to 18%. Adding a -5% code at the second reminder lifts repurchase by roughly 30%, at near-zero marginal cost.
The recovery sequence: timing, channel, message
The right message arrives fast, on the right channel, with a reason to act. Here is a sequence proven on mobile money stores.
| Step | Delay | Channel | Message | Cumulative recovery |
|---|---|---|---|---|
| 1 | 1h | Reminder + direct cart link | ~10% | |
| 2 | 24h | SMS | Reminder + -5% code | ~15% |
| 3 | 72h | Last chance + limited stock | ~18% |
Beyond 3 reminders, recovery plateaus and spam risk rises. We stop at the third.
SMS vs email vs WhatsApp
Channel choice explains half the result. The 2026 orders of magnitude for West Africa:
| Channel | Open rate | Cost/message | Recovery |
|---|---|---|---|
| ~20% | ~0 FCFA | 3-5% | |
| SMS | ~98% | 15-30 FCFA | 8-12% |
| ~90% read | 10-25 FCFA | 10-15% |
Email stays useful as a free complement, but SMS and WhatsApp carry most of the recovery.
Mini case study
Moussa sells phone accessories in Accra. He logs 300 abandoned carts/month with an average basket of 12,000 FCFA, i.e. 3,600,000 FCFA in lost sales. Without reminders, he recovers 0. With the 1h / 24h / 72h sequence at 18%, he recovers 54 orders, i.e. 648,000 FCFA/month. Message cost (3 x 300 x 25 FCFA = 22,500 FCFA) is under 4% of the recovered amount.

FAQ
Why do SMS and WhatsApp beat email in Africa?
SMS opens at ~98% versus ~20% for email, and WhatsApp is the dominant messaging app. The message is read in minutes, not days.
What is the right timing for the first reminder?
Within 1 hour. That's the window where purchase intent is still hot; it alone recovers about 10% of carts.
Should I always offer a discount code?
Not on the first reminder. Save the -5% code for step two: it boosts repurchase by roughly 30% without training customers to wait for a discount.
How many reminders should I send?
Three maximum (1h, 24h, 72h). Beyond that, recovery plateaus and you risk being seen as spam.
Is this compliant with messaging rules?
Yes if the customer provided their number at checkout and can opt out. On WhatsApp, use approved message templates for transactional notifications.
