What is Bulk SMS?
Bulk SMS (also called mass SMS or business SMS service) is the process of sending a large number of text messages simultaneously to a targeted list of mobile numbers. Unlike personal SMS sent one at a time, bulk SMS is delivered through a bulk SMS gateway — a platform that connects your message to telecom networks and delivers it to thousands of recipients in seconds.
Businesses use bulk SMS for a wide range of purposes:
- Promotional offers and sale announcements
- Appointment reminders and booking confirmations
- OTP (One-Time Password) and two-factor authentication
- Order updates and delivery notifications
- Event invitations and festival greetings
- Feedback and survey campaigns
- With a 98% open rate — compared to just 20–22% for email — SMS is the most direct communication channel available to any business today.

- Imagine sending 10,000 personalised messages to your customers — in under 60 seconds, at a fraction of the cost of a newspaper ad. No spam filters. No algorithm. No guesswork. Just a direct line straight to your customer’s pocket.
- That’s exactly what bulk SMS service does.
