Gateway Types

Types of Bulk SMS Gateways in India

Not all SMS gateways serve the same purpose. Choosing the right type ensures compliance, cost efficiency, and optimal delivery.

Transactional

Transactional SMS Gateways

Transactional gateways are designed for critical, time-sensitive messages sent to existing customers — regardless of DND status. They prioritise speed and reliability over volume, with carrier-level priority routing. Requires pre-approved transactional templates under DLT.

Use cases: Transactional SMS for bank OTPs, order confirmations, password resets, flight alerts, and delivery notifications.

Example: "Your OTP for login is 847291. Valid for 5 minutes. Do not share."
Promotional

Promotional SMS Gateways

Promotional gateways handle marketing messages to opted-in subscribers. They respect TRAI's DND (Do Not Disturb) registry and can only deliver during permitted hours (10 AM – 9 PM). Volume throughput is high, making them ideal for large campaign blasts.

Use cases: Promotional SMS solutions for discount offers, sale alerts, new product launches, and seasonal campaigns.

Example: "FLAT 50% OFF this weekend. Shop now at example.com. Reply STOP to opt-out."
Marketing

Marketing SMS Gateways

Marketing gateways bridge promotional sending with advanced campaign features: audience segmentation, A/B testing, campaign scheduling, and performance analytics. They're built for businesses running ongoing, data-driven SMS marketing programmes at scale.

Use cases: Loyalty programme updates, re-engagement campaigns, event invitations, and customer retention sequences.

Example: "Hi Priya, earn double points today only. Visit your nearest store. T&C apply."
Enterprise

Enterprise SMS Gateways

Enterprise gateways offer dedicated infrastructure, SLA guarantees, custom sender IDs, priority carrier routes, and white-label options. They include advanced security, role-based access control, custom reporting, and dedicated account management for large organisations.

Use cases: Banks, insurance companies, e-commerce platforms, and government bodies sending millions of messages monthly.

Example: Large fintech sending 10M+ OTPs monthly with 99.99% SLA requirement.
