The verdict in three sentences
Around 70 % of carts are abandoned, but good recovery wins back 10-25 % of them. The decisive channel in 2026 is WhatsApp: 90 % open rate versus 20 % for email, with a direct conversation that reassures. Timing beats content: a first reminder at 1 hour catches intent while it is still hot, with 24 h and 72 h reminders raking in the rest.
Email, SMS or WhatsApp?
All three work, but not at the same efficiency. Email is free but poorly read; SMS is costly per unit; WhatsApp combines massive open rates with controlled cost.
| Channel | Open rate | Recovery rate | Indicative cost/message |
|---|---|---|---|
| 20 % | 4-8 % | ~0 FCFA | |
| SMS | 55 % | 8-14 % | 25-40 FCFA |
| 90 % | 15-25 % | 10-20 FCFA | |
| Ad retargeting | - | 3-6 % | variable |
WhatsApp wins on almost every axis; keep email as a free complement and SMS for customers without WhatsApp.
Right timing and the promo-code lever
A three-message sequence captures most of the potential. Adding a promo code to the 2nd or 3rd message lifts recovery by about 8 points, but trains customers to wait for the discount: save it for the last reminder.
| Reminder | Delay | Message | Cumulative recovery |
|---|---|---|---|
| 1 | 1 hour | Simple reminder + cart link | 8-12 % |
| 2 | 24 hours | Reminder + social proof/reviews | 12-18 % |
| 3 | 72 hours | -10 % promo code (urgency) | 20-25 % |
The wishlist plays the same role upstream: it captures deferred intent and enables targeted follow-up ("the item on your list is on sale").

Mini case study
Kofi sells accessories in Accra: 1,000 sessions/month, 180 add-to-carts, 54 orders (70 % abandonment). He installs a 3-message WhatsApp recovery flow. Of the 126 abandoned carts, he recovers 20 %, i.e. 25 extra orders. At an 18,000 FCFA average basket, that is 450,000 FCFA/month additional revenue, for a message cost under 8,000 FCFA. The -10 % promo on the 3rd message only costs on orders he would not have had anyway.
FAQ
When should the first reminder go out? At 1 hour: purchase intent is still hot and a simple reminder often suffices. Waiting 24 h for the first message loses half the recovery potential.
Should I always include a promo code? No: save it for the last reminder (72 h). A systematic promo on the first message trains customers to abandon on purpose to trigger the discount, eroding your margin.
Is WhatsApp compliant for this? Yes, provided you have customer consent (checkout opt-in) and use approved message templates. Always leave a clear opt-out option.
What recovery rate should I target? 10 to 25 % of abandoned carts depending on channel and message quality. Well-run WhatsApp puts you at the top of the range, especially with social proof and urgency.
Is a wishlist really useful? Yes: it captures deferred intent you can re-engage on a price drop or restock. A "the item on your list is back" notification converts strongly because demand already exists.
