Why Multi-Channel Messaging Matters for Kenyan SMEs
Kenyan customers use different channels depending on the situation:
- SMS & USSD — For instance, no-internet alerts and transactions.
- WhatsApp — For rich, interactive conversations and high open rates.
- Email — For detailed promotions, receipts, and newsletters.
Relying on one channel limits your reach. A unified strategy ensures you meet customers where they are, increasing response rates and conversions.
Key Benefits of Multi-Channel Messaging for ROI
| Benefit | Impact on ROI | Real-World Example in Kenya |
| Higher Engagement | 3–5x better response rates | SMS alert + WhatsApp follow-up |
