Bulk SMS
Bulk SMS sends thousands of text messages to your customer base at once — through telecom networks, not the internet. Every number on your list gets your message in seconds, whether they're in Mumbai or a small town in Madhya Pradesh.
How it works: Upload your contact list, choose a DLT-registered sender ID and approved template, and send. The platform routes messages across multiple operators, keeping delivery rates high even at peak hours.
Best for: Retail brands running flash sales, banks pushing transaction alerts, hospitals sending appointment reminders, schools notifying parents, logistics firms updating delivery status, and political campaigns. If your audience spans Tier 1 through Tier 3 cities, bulk SMS reaches them all — instantly.

WhatsApp Business API
WhatsApp Business API gives your brand a verified, scalable presence on India's most-used messaging app — not the regular WhatsApp Business app, but an API connection that integrates with your CRM, website, or platform.
How it works: Apply through a WhatsApp Business Solution Provider. Once approved and green-tick verified, you send DLT-compliant template messages, automate chatbot flows, manage two-way conversations, and track delivery from a central dashboard.
Best for: E-commerce handling order updates and returns, fintech companies sending statements, healthcare providers sharing lab reports, EdTech platforms managing student queries. Any business that wants real conversations with customers at scale — not just one-way broadcasts.

RCS for Business
RCS (Rich Communication Services) is what SMS looks like when it evolves. Instead of plain text, you send branded messages with images, product carousels, action buttons, and a verified business badge — directly in the recipient's default messages app.
How it works: Messages are delivered through the telecom operator's RCS network — no separate app download required. If a device doesn't support RCS, the message automatically falls back to SMS.
Best for: Retail and FMCG brands running interactive campaigns, banks sending rich account statements, e-commerce platforms sharing order tracking with tap-to-act buttons, and travel companies delivering boarding passes. Ready to move beyond plain text messaging? RCS is the natural next step.

Voice SMS
Voice SMS (OBD — Outbound Dialling) delivers a pre-recorded audio message to your customer's phone. Their phone rings, they answer, and your message plays — no internet, no reading, no app required.
How it works: Record your message or use text-to-speech with regional language support. The system dials your contact list, plays the recording on pickup, and generates delivery reports with call answer rates.
Best for: Political campaigns reaching rural voters, banks issuing loan payment reminders, healthcare providers sending appointment alerts in local languages, schools announcing results, and FMCG brands in Tier 2–3 markets. When your audience responds better to hearing than reading — Voice SMS reaches where plain text can't.
Get Started
OTP SMS
OTP SMS sends a one-time password to a user's mobile number to verify identity or authorise a transaction — the standard two-factor authentication method across India's digital ecosystem.
How it works: A user triggers an action — login, payment, sign-up. Your platform calls the OTP API, which instantly generates and sends a unique code to their registered number. The user enters it, access is granted. OTPs expire within 30–120 seconds.
Best for: Fintech and banking apps for payment approvals, e-commerce platforms for login, healthcare portals for patient record access, government services for citizen authentication, and any SaaS product needing secure user verification. A delayed OTP costs you the transaction and the customer's trust.

Frequently Asked Questions (FAQ) About Bulk SMS and Messaging Solutions
What is Bulk SMS?
Bulk SMS is a service that allows businesses to send a large number of text messages to multiple mobile users at once. This method is widely used for marketing campaigns, alerts, notifications, and customer engagement. Bulk SMS is cost-effective, delivers messages quickly, and helps organizations reach a wide audience instantly.
How is Bulk SMS different from normal SMS?
Bulk SMS is designed for mass communication, enabling you to send the same message to hundreds or thousands of recipients simultaneously. In contrast, normal SMS is sent to individual contacts or small groups, often with personalized content. Bulk SMS typically uses a sender ID such as a business name, while normal SMS shows the sender’s phone number. Bulk SMS is also more affordable and efficient for large-scale outreach
What is DLT in Bulk SMS?
DLT stands for Distributed Ledger Technology. In the context of bulk SMS, DLT is a regulatory system introduced to prevent spam and ensure message authenticity. Businesses must register their sender IDs and message templates on a DLT platform, which helps telecom operators verify and track every bulk SMS sent. This process ensures compliance and protects recipients from unsolicited messages.
What is the difference between Promotional SMS and Transactional SMS?
Promotional SMS is used for marketing activities such as announcing sales,
offers, or events. These messages can only be sent to non-DND numbers during
permitted hours, usually from 9 AM to 9 PM.
Transactional SMS is used to share essential information like OTPs, order
confirmations, or account alerts. They can be sent 24x7, even to numbers on the
DND list, as they are not promotional in nature.
What is a WhatsApp Business API?
The WhatsApp Business API enables medium and large businesses to communicate with customers at scale through WhatsApp. It allows for automated messaging, notifications, customer support, and integration with CRM systems. Unlike the WhatsApp Business app, which is suitable for small businesses, the API supports high-volume messaging and advanced automation for efficient customer engagement.
