Bulk SMS that reaches every customer, on every phone.

What is Bulk SMS?

Bulk SMS is the sending of text messages from a business to many customers at once through a messaging platform, rather than from an individual handset. It is used for transactional messages such as OTPs and order updates, and for promotional campaigns such as offers and announcements. Because SMS works on every mobile phone without an app or internet connection, it remains one of the most dependable ways to reach customers.

The challenge

Customers miss messages that arrive late, from unknown senders, or not at all.

An OTP that arrives after the timer expires, an order update that never lands, or a promotion sent to the wrong list all cost trust. Most businesses do not need more messages. They need messages that arrive on time, from a recognisable sender, with proof of delivery.

Time-sensitive messages such as OTPs need consistent, fast delivery.
Unrecognised senders reduce open rates and invite spam reports.
Without delivery reports, teams cannot tell what actually reached customers.
In India, promotional and transactional traffic must follow DLT rules.

A business SMS service built around delivery, identity and control.

Send from a registered Sender ID, choose the right route for transactional or promotional traffic, schedule campaigns in advance and track delivery for every message. Our team helps with DLT registration and template approval so your workflows are ready for the Indian market.

Why businesses use SMS

SMS reaches customers where other channels cannot. It does not depend on an app being installed, a notification being enabled or a data connection being active. That makes it the default channel for messages that must be seen, such as verification codes, payment alerts and appointment reminders.

Universal reach across feature phones and smartphones
Short, direct messages that are read quickly
Reliable for urgent, time-bound communication
Simple to integrate with existing systems

Promotional SMS

Promotional SMS is for offers, product launches, seasonal campaigns and re-engagement. It is sent to customers who have opted in, within the hours permitted by regulation, and from a promotional header. We help you segment lists, schedule sends and measure results so campaigns stay relevant instead of noisy.

Transactional SMS

Transactional SMS carries information the customer expects: an order confirmation, a delivery update, a balance alert or a booking change. These messages are triggered by events in your systems and use a dedicated route so they are not delayed behind marketing traffic.

OTP and verification

One-time passcodes protect sign-ins, transactions and account changes. OTP traffic is prioritised for speed, because a code that arrives after the timer runs out is worse than no code at all. Our team helps you set up OTP templates and monitor delivery so verification does not become a drop-off point.

Notifications and reminders

Appointment reminders, payment due dates, shipment updates and service notices reduce missed appointments and support calls. Schedule reminders ahead of time, personalise them with customer details and confirm delivery for each message.

Delivery insights

Every message returns a delivery status. Campaign summaries show sent, delivered and failed counts so you can spot invalid numbers, network issues or template problems early and keep your lists healthy.

Bulk SMS questions, answered.

Clear answers to the questions we hear most. If yours is not here, ask us directly.

What is the difference between promotional and transactional SMS?

Transactional SMS carries information a customer expects, such as an OTP or order update, and can be sent at any time. Promotional SMS carries offers and marketing content, is sent only to customers who have opted in, and follows time-of-day restrictions. The two use separate routes and headers.

Do I need DLT registration to send SMS in India?

Yes. Businesses sending SMS in India must register their entity, headers (Sender IDs) and message templates on a DLT platform. We guide you through the process so your workflows are ready before you send.

Can I send OTPs through Bulk SMS?

Yes. OTP traffic is treated as transactional and prioritised for fast delivery. We help you set up OTP templates and monitor delivery performance.

How do I track whether a message was delivered?

Every message returns a delivery status. Campaign reports summarise sent, delivered and failed counts so you can act on issues quickly.

Can I schedule SMS campaigns?

Yes. Campaigns can be scheduled for a specific date and time, and large sends can be staggered to manage load.

Can SMS be combined with other channels?

Yes. Many businesses use SMS for urgent updates, RCS for richer content, email for detailed communication and voice for reminders. We help you choose the right mix.
