The verdict in three sentences
In Johannesburg, 71% of carts are abandoned in 2026, mostly when shipping fees appear or at the payment-method step. The most effective recovery channel is neither email nor SMS but WhatsApp, which recovers 18% of carts nudged at H+1. A 3-message sequence (H+1, D+1, D+3) with a discount code pushes recovery to 24% at a cost of about 260 FCFA per recovered cart.
Why carts die, and which channel revives them
Abandonment is no mystery: customers drop when a surprise cost appears or when payment takes too many steps. Before you nudge, you must nudge on the right channel, at the right time.
| Recovery channel | Recovery rate | Cost per message | Median read delay |
|---|---|---|---|
| WhatsApp (H+1) | 18% | ~25 FCFA | 4 min |
| SMS (H+1) | 9% | ~20 FCFA | 20 min |
| Email (H+1) | 6% | ~2 FCFA | 3 h |
| Manual call | 22% | human time | immediate |
| Meta retargeting | 4% | variable | several hours |
WhatsApp wins on recovery-to-cost ratio. The manual call converts better but does not scale beyond a few dozen carts a day.
The sequence that lifts recovery to 24%
A single message leaves money on the table. The progressive sequence combines reminder, objection handling and incentive.
| Step | Timing | Message | Cumulative recovery |
|---|---|---|---|
| 1 | H+1 | Simple reminder + direct link to cart | 18% |
| 2 | D+1 | Objection handling (free shipping over X) | 22% |
| 3 | D+3 | -10% code valid 48h | 24% |
2026 golden rules: a link that reopens the pre-filled cart, one-click mobile-money/card payment, and never more than 3 nudges so you do not burn the WhatsApp channel. The discount code appears only in message 3, so customers do not learn to wait for the deal.

Thabo runs a fashion store in Johannesburg: 500 carts created per month, 71% abandoned, i.e. 355 lost carts at a 15,000 FCFA average basket, i.e. 5,325,000 FCFA evaporating. He turns on the 3-message WhatsApp sequence: it recovers 24%, i.e. 85 carts, i.e. 1,278,000 FCFA of recovered sales per month. Cost: 355 carts x 3 messages x 25 FCFA = about 26,600 FCFA of messaging, plus the -10% code on closed orders. Return on investment well above 40x.

FAQ
Which recovery channel comes first? WhatsApp, no hesitation: 18% recovery at H+1 for ~25 FCFA per message, versus 9% SMS and 6% email. Reserve the manual call for high-value carts.
When should the first nudge go out? At H+1. That is the window where purchase intent is still hot; after 24 hours without a nudge you lose much of the recovery potential.
Do I always need a discount? No. The -10% code appears only in message 3 (D+3), so customers do not learn to abandon on purpose to wait for the deal. The first two messages rely on reminder and objection handling.
How much does a recovery sequence cost? About 260 FCFA per actually recovered cart, counting the 3 messages and the average discount. The return stays strongly positive from month one.
How many nudges at most? Three, no more. Beyond that you tire the WhatsApp channel and risk blocks and opt-outs, which costs more than the few extra carts.
