The verdict in three sentences
In Accra, email cart recovery is nearly dead: 18 to 24 % open rate, even fewer clicks. WhatsApp opens at 85-95 % and SMS stays highly effective, which recovers +8 to +15 % of abandoned carts. With a cost per message of 12-60 FCFA and a decent average ticket, the ROI of a well-sequenced campaign reaches x6 to x12.
Three recovery channels, one dominant winner
The channel is not everything, but it sets the performance ceiling. WhatsApp dominates on open rate, SMS on cost and universality, email on richness but poor readership here.
| Channel | Open rate | Cost / message | Cart recovery |
|---|---|---|---|
| 85-95 % | 30-60 FCFA | +10 to +15 % | |
| SMS | 70-90 % | 12-25 FCFA | +6 to +11 % |
| 18-24 % | ~2-5 FCFA | +2 to +4 % |
The 2026 strategy: WhatsApp first for impact, SMS as relay for reach and cost, email only as a top-up for those without a usable number.
The J0 / J1 / J3 sequence that converts
Timing matters as much as the channel. The first reminder must go out fast, while intent is hot; the next ones space out and add a light incentive.
| Timing | Channel | Message | Objective |
|---|---|---|---|
| J0 +30-60 min | "Your cart is waiting" + direct link | Catch hot intent | |
| J1 (24 h) | SMS | Reminder + delivery/payment reassurance | Remove doubt |
| J3 (72 h) | Small incentive (free shipping, -5 %) | Trigger the decision |
The optimal first-reminder delay is 30 to 60 minutes: beyond that, intent fades fast. Never exceed 3 messages to avoid annoyance and sender-number degradation.

Mini case study
Aisha runs a cosmetics shop in Accra: 400 abandoned carts a month, average ticket 15,000 FCFA. Without recovery she gets nothing back. With the J0 WhatsApp / J1 SMS / J3 WhatsApp sequence she recovers 12 % of carts, that is 48 sales. Campaign cost: 400 x (60 + 25 + 60) FCFA at worst = 58,000 FCFA. Recovered revenue: 48 x 15,000 = 720,000 FCFA. Net ROI: about x11 after margin. Every franc invested in recovery brings back more than ten.
FAQ
Why does email work so poorly in Accra? Inboxes are rarely checked and open rate caps at 18-24 %. WhatsApp, by contrast, is opened several times a day, hence its 85-95 % open rate.
How much does a WhatsApp reminder cost in 2026? The order of magnitude is 30 to 60 FCFA per message via an official solution, versus 12 to 25 FCFA for an SMS. The WhatsApp premium is offset by the open rate.
What is the best time for the first reminder? Between 30 and 60 minutes after abandonment, while purchase intent is still hot. Waiting 24 h sharply lowers recovery.
How many messages before stopping? Three at most across the J0/J1/J3 sequence. Beyond that you tire the customer and risk reports that degrade the sender number.
What ROI to expect? With a decent average ticket, a well-sequenced campaign returns x6 to x12, cart recovery being one of the most profitable levers in e-commerce.
