The verdict in three sentences
Most visitors who add to cart do not pay on the first try: between 65 and 75 % abandon. Yet in Senegal, WhatsApp is opened at about 90 % while email caps at 20 %: following up on WhatsApp, with a pre-filled Wave payment link, recovers 15 to 25 % of abandoned carts. Well sequenced (H+1 then H+24, promo code in the second wave), this recovery shows a channel ROI around 8x.
Email vs WhatsApp: why the channel changes everything
Cart recovery has existed for 15 years in Western e-commerce, almost always by email. In West Africa, email is rarely checked and often filtered. WhatsApp is the daily conversation channel.
| Metric (2026 order of magnitude) | ||
|---|---|---|
| Open rate | 15-20 % | 85-90 % |
| Click rate | 2-3 % | 25-35 % |
| Average time to read | 6-24 h | 1-15 min |
| Cart recovery | 3-6 % | 15-25 % |
| Embedded payment link | rare | Wave/OM pre-filled |
| Cost per message | near zero | near zero |
Time-to-read is decisive: a cart followed up within minutes, while purchase intent is still hot, converts far better than an email read the next day.
The recovery sequence that converts
| Step | Timing | Message | Lever |
|---|---|---|---|
| Follow-up 1 | H+1 | Product reminder + pre-filled Wave link | Intent still hot |
| Follow-up 2 | H+24 | Reminder + promo code -5 % | Price incentive |
| Follow-up 3 | H+72 | Last chance + limited stock | Urgency / scarcity |
Golden rule: every message contains the exact amount and a one-tap payment link. You do not ask the customer to come back and find their cart; you bring the payment to them.

Mini case study
Ibrahim sells phone accessories online in Thies. He logs 200 abandoned carts per month, average cart 12,000 FCFA, i.e. 2,400,000 FCFA of pending sales. Without follow-up he would recover ~0. With the WhatsApp sequence he recovers 20 % of carts, i.e. 40 orders = 480,000 FCFA per month. The -5 % promo applied to half those sales costs him about 12,000 FCFA: an ROI well above 8x on the time invested.
FAQ
Is WhatsApp follow-up allowed? Yes if the customer left their number in the funnel and you follow up on an order they initiated themselves. Stay factual, offer a pickup link and a way to opt out.
What timing for the first follow-up? About 1 hour. Early enough to catch live intent, late enough not to seem intrusive if the customer finishes alone.
Should you always offer a promo code? No, only in the second wave. Offering -5 % on the first follow-up erodes margin on customers who would have converted without a discount.
How does the pre-filled Wave link work? You generate a payment link for the exact cart amount: the customer taps once, confirms in Wave, and it is collected. Zero re-entry, zero friction.
What recovery rate to target? A realistic 2026 goal is 15 to 25 % of abandoned carts recovered, often +10 to +20 % total revenue with no extra acquisition.
