OTP SMS engineered for login-critical latency
Checkout and login should not wait on a promotional queue. OTP traffic is treated as a reliability problem, not a campaign.
Problem
Late OTPs abandon checkouts
Users retry, lock accounts, and complain on social. Engineering cannot see whether delay is upstream, template, or handset.
Solution
OTP-specific routing and observability
Dedicated templates, retry policy, and status webhooks give product teams the telemetry they need.
Capabilities
Fast lane routing
OTP is isolated from bulk campaigns.
Webhook status
Your app learns delivered vs failed.
Retry policy
Controlled resend without SMS bombing.
Fallback design
Pair with WhatsApp or voice OTP where scoped.
