The challenge
A Nairobi fintech was losing sign-ups to slow and failed OTP delivery during peak M-Pesa hours, and lacked visibility into why messages failed.
What we did
- Moved OTP traffic to a transactional Sender ID with priority routing
- Enabled real-time signed delivery reports for full visibility
- Tuned per-network routing for Safaricom peak windows
