Last month a logistics company came to us. SMS delivery alerts through one provider, WhatsApp tracking through another, email invoices through a third. When their SMS provider went down for 40 minutes, the ops team scrambled manually — no fallback, no single view, no way to switch fast.
That's the real cost of building on three separate APIs. Businesses in Kenya using a unified messaging API spend less on integrations, recover faster from outages, and ship faster.
"Most businesses never calculate the true cost of separate messaging APIs. That's why they overpay for years."
— Albert Ondicho, CTO TechVoyage
The Hidden Cost of Separate APIs
- Integration time: 3–5 developer days per channel — 30,000–80,000 KES before you send a single message.
- Monthly overhead: 3 invoices, 3 support contacts, 3 dashboards to monitor.
- Outage risk: One provider fails → no automatic fallback → hours lost switching manually.
- Zero visibility: No single view of which channel is actually converting.
What Propel API Changes
- One integration — one doc, one connection, SMS + WhatsApp + email from the same API call.
- One dashboard — delivery rates, replies, costs. One invoice. One support contact.
- Smart routing (optional) — OTPs via SMS, promos via WhatsApp, receipts via email. Configured once, runs automatically.
"Businesses don't buy channels. They buy delivered messages and happy customers."
