FAQs — Bulk SMS Service
Is DLT registration mandatory for sending bulk SMS in India?
Yes. TRAI requires every business to register its entity, sender ID headers and content templates on a DLT platform before sending commercial SMS. Guru SMS provides step-by-step DLT registration assistance, and most clients complete the entire process within two working days.
What is the difference between promotional and transactional SMS?
Promotional SMS carries marketing content, is delivered to non-DND or opted-in numbers during TRAI-permitted daytime hours, and achieves 90-95% delivery. Transactional SMS covers OTPs, alerts and confirmations, runs 24x7 to all numbers including DND, and delivers at 98-99%.
Can I send SMS in Hindi, Odia or other regional languages?
Absolutely. The platform supports Unicode messaging in all major Indian scripts, including Hindi, Odia, Bengali, Tamil, Telugu, Kannada, Malayalam, Gujarati, Punjabi and Marathi. Regional language campaigns regularly outperform English ones in tier-2 and tier-3 markets, and our team helps you register multilingual templates on DLT.
How fast are messages delivered, and what delivery rate can I expect?
Messages route through 230+ direct operator connections, so most reach handsets within seconds of submission. Transactional traffic consistently delivers at 98-99% and promotional campaigns at 90-95%. Real-time delivery analytics show delivered, pending and failed status for every single number.
What is a sender ID and can I use my brand name?
A sender ID is the six-character header that appears in place of a phone number on the recipient handset. You can register headers derived from your brand name on DLT, and we help you choose IDs that clear approval quickly while staying instantly recognisable to customers.
Do you provide an API for sending SMS from my software?
Yes. A REST-based bulk SMS API with sample code in PHP, Java, Python and .NET lets your website, app or CRM trigger messages automatically. The same DLT templates and sender IDs work across both the web panel and the API.
How do I get started and how long does setup take?
Call +91-9853084604 or email info@gurusms.in for a live demo. Account creation takes minutes and DLT registration usually completes within two working days. Businesses already registered on DLT can start sending the same day after header and template mapping.
Can I schedule festive campaigns in advance?
Yes. Campaign scheduling lets you queue Diwali, Holi, Raksha Bandhan or end-of-season blasts weeks ahead, fix exact send times and edit or cancel until the moment of dispatch. Many of our 500+ clients lock their entire festive calendar in one sitting.
