Bulk SMS for Hotels and Resorts

Q: How do hotels and resorts use bulk SMS?

Hotels and resorts use bulk SMS for booking and reservation confirmations, check-in and check-out details, OTP-based logins and verification, seasonal package offers, loyalty and membership updates, banquet and event promotions, and post-stay feedback requests. SmsHorizon has supported this kind of messaging since 2011 for 3,000+ businesses across India.

Q: Can I send promotional offers to past guests?

Yes. Promotional SMS lets you reach opted-in, non-DND guests with seasonal packages, festival deals and banquet offers within TRAI's 10am to 9pm window. Booking confirmations, check-in details and OTPs go out as transactional SMS at any hour, including to DND numbers.

Q: Is your API suitable for booking confirmations and OTPs?

Yes. Our HTTP and SMPP APIs connect to your property management or booking system to fire instant reservation confirmations and OTPs, with priority transactional routing, sub-3-second delivery and detailed delivery reports.

Q: How quickly can a hotel go live?

Typically 3 to 5 days. Most of that time is the DLT registration and sender ID approval, which we handle for you. Once those clear, your account is ready and you can send your first campaign or wire up the API right away.

Q: Do you help with DLT registration?

Yes, free of charge. TRAI requires entity, header and template registration on the DLT portal for all commercial SMS under the TCCCPR rules. Our team walks you through the entire process and handles the paperwork.

Q: How much does bulk SMS cost for a hotel or resort?

Bulk SMS is pay-as-you-go: you pay per message and the rate falls as your volume grows, with no setup fee or monthly rental. Transactional, OTP and promotional routes are each priced per SMS, and a longer message counts as more than one SMS. See our pricing page for current rates.

Q: Which mobile networks do you cover?

We deliver across every major network, including Jio, Airtel, Vi and BSNL, over direct operator routes. Transactional and OTP messages reach all numbers, including DND, while promotional sends follow TRAI's DND rules and the 10am to 9pm window under the DLT framework.

Messaging that keeps guests informed

Hospitality runs on timely, trusted communication. A guest who gets an instant reservation confirmation, a clear check-in message and a well-timed offer feels looked after long before they reach the front desk.

SMS reaches every guest with a mobile number, with no app to install and no inbox to compete with. That makes it the most dependable channel for the moments that matter most around a stay.
