What is Bulk SMS and how does it work in India?
Bulk SMS is a service that lets businesses send the same text message to thousands of mobile numbers in seconds using a DLT-approved sender ID. In India, every commercial SMS — promotional, transactional or OTP — must be sent through a TRAI-DLT registered template via licensed operator routes (Jio, Airtel, Vi, BSNL), with real-time delivery reports and 99%+ deliverability.
- Promotional SMS — offers and marketing (9am–9pm, non-DND)
- Transactional SMS — OTP, alerts, invoices (24×7, all numbers)
- API SMS — REST integration for apps, CRMs and websites
- Plans from ₹2,200 (10,000 SMS) — as low as 18 paise per SMS
