OVERVIEW

Communication Infrastructure That Keeps Customers Informed

Modern businesses need to communicate with customers across multiple channels — order confirmations via SMS, invoices via email, OTPs for verification, promotional campaigns for engagement. Building this messaging infrastructure requires navigating DLT registrations, template approvals, email deliverability, and provider failover.

Whether you need to send 100 OTPs per day or 100,000 promotional messages, our infrastructure scales seamlessly and delivers reliably.

OTP Verification

Secure OTP system with configurable expiry, retry limits, rate limiting, and multi-channel delivery (SMS + email fallback) for user registration, login, and transaction verification.
