The verdict in three sentences
Between 60 and 80 % of carts are abandoned before payment in a Johannesburg store, and most for recoverable reasons: surprise fees, hesitation, awkward checkout. A three-touch WhatsApp sequence paired with a pre-filled payment link typically recovers 8 to 18 % of those lost carts at near-zero marginal cost. The lever is not the discount: it is timing and removed friction at payment.
The three-touch sequence
An effective recovery flow is neither too aggressive nor too late. Here is the recommended cadence for 2026, tuned to South African mobile behaviour.
| Touch | Delay | Channel | Message | Incentive |
|---|---|---|---|---|
| 1 | +30 min | Reminder + pre-filled checkout link | None | |
| 2 | +6 h | Stock reminder + delivery reassurance | None | |
| 3 | +24 h | Last chance | 5-10 % code | |
| Cold nudge | +72 h | WhatsApp/SMS | Gentle reactivation | Margin-based |
| Stop | +7 d | — | End of sequence | — |
The first touch does the heavy lifting: a simple pre-filled payment link (amount, items, delivery already calculated) removes the friction that scared the buyer off. Only pull out the promo code on the third touch, so you don't train customers to abandon just to earn a discount.
Incentive cost vs margin and segmentation
A promo code only pays off if margin supports it. Segment by basket value: big baskets deserve human reassurance, small ones an automatic code.
| Basket segment | Target recovery | Incentive | Marginal cost |
|---|---|---|---|
| < ZAR 250 | 8-12 % | 5 % code or none | ~ZAR 0-12 |
| ZAR 250-850 | 12-16 % | 7 % code | ZAR 17-60 |
| ZAR 850-2,500 | 14-18 % | Free delivery | delivery cost |
| > ZAR 2,500 | 15-20 % | Human WhatsApp call | agent time |
| Opt-in required | — | POPIA consent | compliance |
Golden rule: the third-touch code should cost less than 30 % of margin on the average basket. And never send without explicit opt-in — WhatsApp consent protects your number from a ban and meets the 2026 framework.

Mini case study
Thabo sells phone accessories in Johannesburg. He gets 1,200 carts/month, of which 840 abandoned (70 %). He turns on the WhatsApp + payment-link sequence: touch 1 (+30 min) recovers 6 %, touch 2 (+6 h) 3 %, touch 3 (+24 h, 7 % code) 4 %. Total recovered: 13 %, i.e. 109 carts at a ZAR 370 average basket = ZAR 40,000 extra revenue/month. Code cost: ~ZAR 1,800. Net ROI: over 20x.
FAQ
How many carts can I really recover? A well-tuned sequence recovers 8 to 18 % of abandoned carts. The strongest lever is not the discount but the pre-filled payment link sent within 30 minutes.
Should I always offer a promo code? No. Reserve the incentive for the third touch so you don't train customers to abandon. On big baskets, a human WhatsApp call converts better than a code.
WhatsApp or SMS for recovery? WhatsApp first: open rates exceed 90 % and it supports a clickable checkout link. Keep SMS as a fallback for numbers without WhatsApp.
Is sending these messages legal? Only with explicit opt-in at checkout. Consent also protects your WhatsApp Business number from a spam report under POPIA.
How do I adapt this to card and EFT markets? Swap the payment link for card, EFT and SnapScan checkout, keep the same WhatsApp cadence; abandonment and recovery rates stay comparable.
