Cinematic still for Reaching every device: USSD, SMS, and WhatsApp

A smartphone-and-email-only product quietly excludes a large share of users in emerging markets. Reaching everyone means meeting people on the channel they already have, including a feature phone with no data plan.

The channels that matter

  • USSD works on any phone, no data, no app, the *123# menus people already use for banking and airtime. It is the most inclusive channel there is.
  • SMS is universal and reliable for confirmations, alerts, and one-time codes.
  • WhatsApp Business is the dominant chat channel across much of the world, with templated and session messaging.
  • Voice / IVR reaches users who prefer to listen and speak, including multilingual flows.
  • Email remains the right rail for receipts and longer-form transactional messages.

How we wire it

Africa's Talking covers SMS, USSD, and voice; the WhatsApp Business API covers chat; Resend covers transactional email. One engagement layer, every device, the reach a single-channel vendor cannot match. It is the same omnichannel capability behind Tukutane and Kipaji.
