The verdict in three sentences
An abandoned cart is not a lost sale, it is a pending one: the customer showed strong intent, and often a reminder is all it takes. An SMS + WhatsApp recovery sequence recovers 5 to 15 % of abandoned carts for a few dozen FCFA per message. In 2026, SMS opens at over 90 % and WhatsApp at 70-80 %, while email caps at 15-25 % in Senegal and Côte d'Ivoire.
Email vs SMS vs WhatsApp: open rate decides
The recovery channel changes everything: an unread message recovers nothing. Here are the compared performances in the 2026 West African market.
| Channel | Open rate | Cost / message | Read delay | Typical recovery |
|---|---|---|---|---|
| 15-25 % | ~0 FCFA | Hours to days | 1-3 % | |
| SMS | > 90 % | 10-25 FCFA | Minutes | 3-8 % |
| 70-80 % | 5-15 FCFA | Minutes to hours | 4-10 % | |
| SMS + WhatsApp combined | Cumulative | 15-40 FCFA | Minutes | 5-15 % |
SMS wins on open rate, WhatsApp wins on richness (product photo, clickable payment link). Combined, they form the market's most effective sequence.
The recovery sequence that works
Timing is decisive: too early annoys, too late and the urge has faded. Here is a typical sequence and its recovery rates.
| Timing | Channel | Message | Incentive | Cumulative recovery |
|---|---|---|---|---|
| + 1 hour | SMS | Simple reminder + cart link | None | 2-4 % |
| + 24 hours | Product photo + payment link | Free shipping | 4-9 % | |
| + 72 hours | Last chance | -5 % expiring code | 5-13 % | |
| + 7 days | SMS | Gentle reactivation | Product still available | 5-15 % |
The first reminder at 1 hour with no discount captures technical abandons (interrupted payment, passing doubt) without shaving margin. The discount only appears on the second or third reminder, so customers do not learn to abandon on purpose.
Mini case study
Ousmane runs an online shoe store in Dakar. He records 400 abandoned carts a month, average basket 22,000 FCFA, or 8,800,000 FCFA of potential sales lost.
He sets up an SMS (1 h) + WhatsApp (24 h and 72 h) sequence. It recovers 11 % of carts, or 44 sales at 22,000 FCFA = 968,000 FCFA/month in recovered revenue. Sending cost (about 3 messages × 400 carts × 20 FCFA) is around 24,000 FCFA/month, plus a -5 % discount on part of recovered sales (~30,000 FCFA). Net ROI exceeds 17x: every 1 FCFA spent on recovery returns over 17 FCFA in revenue. Over a year, that is nearly 11.6 million FCFA in otherwise-lost sales.

FAQ
When is the best time for the first reminder?
One hour after abandonment, by SMS, with no discount: this captures technical abandons and passing doubts. The longer you wait, the more intent fades and the costlier the incentive needed.
Should I offer a discount on the first reminder?
No, it teaches customers to abandon on purpose to get a code. Reserve the discount for the second or third reminder, and make it time-limited.
SMS or WhatsApp?
Both: SMS opens at over 90 % and reaches everyone, WhatsApp allows a product photo and clickable payment link. The combined sequence recovers 5 to 15 % of carts.
How many reminders should I send?
Three to four maximum over seven days. Beyond that, returns drop and the risk of annoying the customer rises, hurting the long-term relationship.
Is it worth it for a small store?
Yes, very: at a few dozen FCFA per message to recover carts worth several thousand FCFA, ROI often exceeds 10x. It is one of a store's most profitable automations.
