Average African cart abandonment runs 71-78% in 2026 (vs 69% global). Local reasons: flaky 3G, mobile money hesitation, physical-market price comparison. A well-tuned recovery sequence wins back 22-28% of these carts.

TL;DR

- 3-channel sequence: WhatsApp at H+1, SMS at D+1, Email at D+3.

- Average recovery on 19 stores (SN, CI, CM, NG, KE): 23.8%.

- Templates and timing vary by country — WhatsApp dominates in SN/CI, SMS in CM/CI/NG, email in KE/ZA.

Why multi-channel in Africa

Email-only works in few countries. WhatsApp is the backbone.

Pitfalls

• Bonus on message 1 — customer feels held hostage. Bonus only on message 2.
• Over-nagging — past D+7 = spam. Hard stop.
• Off-policy WhatsApp templates — ban non-approved Meta marketing templates. See WhatsApp Business templates →.
• Unsigned recovery link — always HMAC-sign to prevent customer-to-customer sharing.

FAQ

Q: Time between messages?

A: 15 min email → 1h WhatsApp → 24h SMS → 48h WhatsApp #2 → 72h final email. Past that, stop.

Q: Need separate WhatsApp opt-in?

A: Yes, Meta requirement + good practice. At signup: checkbox "I consent to receive transactional WhatsApp messages".

Q: WhatsApp Business API cost?

A: Via Brevo or 360dialog: €0.01-0.07/conversation (UTILITY or MARKETING) by country. ~€10-50 / 1000 messages.

Conclusion

Multi-channel cart abandonment is no longer optional in African e-commerce. It's the #1 lever to reach 100M XOF/month without growing acquisition spend. The sequence above codes in 1 week and pays back in 2-4 weeks per volume.
