2

Get your SMS templates approved

Submit OTP, transactional and promotional templates for DLT approval before they can be sent live.

3

Choose your routes

Pick transactional routes for OTPs and alerts, and promotional routes for offers within TRAI's permitted sending hours.

4

Send via dashboard or API

Trigger single or bulk sends from the panel, or integrate the REST API directly into your application.

5

Monitor delivery in real time

Watch sent, delivered and failed status live, and pull reports for a specific campaign or date range.

Where Bulk SMS Teams Use It

Transactional Alerts

Deliver OTPs, order confirmations and payment alerts over dedicated transactional routes built to stay fast even when promotional traffic is high across the network.

Promotional Campaigns

Reach opted-in customers with offers and announcements on DLT-approved promotional routes, timed to the hours TRAI permits for commercial messaging.

Two-way Engagement

Let customers reply with a keyword to confirm an order, opt out of a list or request a callback, with responses routed straight into your system.

Frequently Asked Questions

What is DLT registration and why is it required?

DLT (Distributed Ledger Technology) registration is TRAI's mandatory framework for entities and message templates sending commercial SMS in India - we handle the entity and template registration for you.

What's the difference between transactional and promotional SMS?

Transactional SMS (like OTPs and order alerts) can be sent to any number at any hour, while promotional SMS only reaches opted-in numbers within TRAI's permitted time window.

What delivery rates can I expect for bulk campaigns?

Delivery rates depend on route type and carrier, but our high-throughput transactional and promotional routes are built to maintain industry-leading delivery even during peak-hour sends.

Can I see delivery status for each message I send?

Yes, real-time delivery reports show sent, delivered and failed status for every message, accessible from your dashboard or via the reporting API.
