The verdict in three sentences
In West Africa, recovering an abandoned cart by email is a mistake: the email open rate caps at 20 % versus 95 % for SMS and 80 % for WhatsApp in 2026. A well-calibrated 3-message sequence recovers 12 to 20 % of abandoned carts. At 15-25 FCFA per SMS and a 15,000 FCFA average basket, the return on investment is measured in tens to one.
Why SMS and WhatsApp beat email
The recovery channel matters as much as the message. In West Africa, email stays secondary: many buyers don't check an inbox daily, whereas the phone is checked constantly. The figures speak for themselves.
| Channel | Open rate | Average read delay | Cost per message |
|---|---|---|---|
| 20 % | several hours | ~0 FCFA | |
| SMS | 95 % | < 3 min | 15 to 25 FCFA |
| WhatsApp Business | 80 % | < 15 min | 10 to 30 FCFA |
| Push notification | 40 % | variable | ~0 FCFA |
| Phone call | 60 % (picked up) | immediate | agent time |
SMS wins on opening, WhatsApp on richness (product image, pay button, conversation). Combining both is ideal: SMS for the first alert, WhatsApp for the relationship.
The 3-message sequence that converts
Effective recovery is not a single message: it is a time-spaced sequence with a growing incentive. Here is a proven template and its yield.
| Message | Delay after abandon | Channel | Content | Cumulative recovery |
|---|---|---|---|---|
| 1 | 30 min | SMS | Simple reminder + link | 5 to 8 % |
| 2 | 4 h | Product image + pay button | 9 to 14 % | |
| 3 | 24 h | SMS/WhatsApp | -5 % incentive or free delivery | 12 to 20 % |
Beyond 3 messages, marginal yield falls and the risk of annoying the customer rises. The third message with a small incentive is often what tips hesitant buyers over the line.

Mini case study
Fatou runs a ready-to-wear Instagram page in Thies, 400 abandoned carts per month, average basket 16,000 FCFA. Without recovery, these 6,400,000 FCFA of carts stayed lost. With a 3-message sequence recovering 15 %, she catches 60 orders, i.e. 960,000 FCFA per month. The cost: about 400 SMS + WhatsApp at 20 FCFA average, or 24,000 FCFA in messages. The ROI exceeds 40 to 1.
FAQ
Is SMS really read at 95 %?
Yes, SMS remains the most opened channel in West Africa, with near-immediate reading. That is what makes it the best first touchpoint for recovery.
Should you offer an incentive in the first message?
No. The first message should be a simple reminder. Reserving the incentive (-5 % or free delivery) for the third message avoids discounting sales that would have happened anyway.
Is WhatsApp Business allowed for recovery?
Yes, via the official API and with customer consent. You use approved message templates and respect contact windows to stay compliant.
How many messages before saturating the customer?
Three maximum over 24 to 48 hours. Beyond that, extra recovery drops below 2 % and the unsubscribe risk rises.
Can the whole sequence be automated?
Yes. The sequence triggers automatically once abandonment is detected, with no manual work, which keeps it profitable even at high volume.
