Frequently Asked Questions — Bulk SMS, WhatsApp API & IVR

Quick answers to questions businesses ask us every day about SMS marketing, WhatsApp API, DLT registration, and IVR services in India.

DLT (Distributed Ledger Technology) registration is mandatory to send bulk SMS in India as per TRAI regulations. It prevents SMS spam by requiring businesses to register their Sender ID and message templates before sending any commercial messages. Without DLT registration, your SMS will be blocked by operators and will never reach customers.

Bulk SMS is the process of sending a single text message to thousands of recipients simultaneously. It is used for promotional offers, transactional alerts, OTP verification, reminders, and updates. Any business — schools, hospitals, banks, retail stores, e-commerce companies, real estate firms, and more — can use bulk SMS to communicate with their customers instantly.

No. Our system automatically filters out DND (Do Not Disturb) registered numbers. As per TRAI rules, promotional SMS cannot be delivered to DND numbers. Transactional SMS such as OTPs and account alerts, however, can be delivered to DND numbers because they are considered essential communications.

WhatsApp Business API is a platform designed for medium and large enterprises to send messages at scale, integrate with CRM systems, and automate customer communication. Unlike the WhatsApp Business app (which is for small businesses and limited to one device), the API supports multiple agents, bulk messaging, chatbots, and integration with your existing software. It requires a verified business account and is accessed through a provider like Meta Reach Marketing.

IVR (Interactive Voice Response) is an automated telephone system that interacts with callers using pre-recorded voice prompts and collects input via keypad presses (e.g., "Press 1 for Sales, Press 2 for Support"). IVR operates 24/7, handles high call volumes without additional staff, supports multiple languages, and routes customers to the right department — reducing wait times and operational costs significantly.

Bulk SMS pricing in India depends on the volume, SMS type (promotional or transactional), and the provider. At Meta Reach Marketing, we offer competitive per-SMS pricing with no hidden charges. Transactional SMS (OTP, alerts) typically costs slightly more than promotional SMS. Contact us at +91 7669999219 for a customised quote based on your monthly volume and requirements.

OBD (Outbound Dialler) is a service that sends pre-recorded voice messages to a large list of phone numbers automatically. Businesses use OBD for promotional campaigns, payment reminders, appointment confirmations, and customer surveys. There is no need for a human agent — the system dials numbers and plays the recorded message when the call is answered.

RCS (Rich Communication Services) is the next evolution of SMS that works inside the default messaging app on Android phones without requiring any third-party app download. Unlike plain SMS, RCS supports images, videos, GIFs, interactive buttons, carousels, and branded sender profiles. It offers WhatsApp-like rich media experiences through the native SMS app. Meta Reach Marketing provides RCS services supported by Jio, Airtel, and Vodafone Idea.

Voice OTP delivers a one-time password to users via an automated phone call instead of an SMS. It is more reliable in areas with poor SMS signal and is considered more secure because the OTP is spoken aloud over a live call — making it harder for attackers to intercept. Businesses use Voice OTP for account login, payment authorisation, and two-factor authentication on banking apps, e-commerce platforms, and fintech services.

A Sender ID is the name or number that appears in the "From" field when a recipient receives your SMS. For example, messages from a bank may show "HDFCBK" as the Sender ID. In India, Sender IDs must be registered on the DLT platform before use. A recognisable Sender ID builds customer trust and improves SMS open rates.

Yes. Bulk SMS personalisation lets you insert dynamic fields such as the customer's name, order number, appointment date, or account balance into each message. For example: "Dear Rahul, your order #12345 has been dispatched." Personalised messages see significantly higher engagement and response rates compared to generic broadcast messages.

A toll-free number allows customers to call your business at no cost to themselves — the business pays for the call. Numbers starting with 1800 are common toll-free numbers in India. Having a toll-free number increases inbound calls, builds brand credibility, and encourages customers to reach out without hesitation. It is ideal for customer support, feedback lines, and lead generation.

Click-to-Call is a feature that allows website or app visitors to initiate a phone call with your business simply by clicking a button — no need to manually dial a number. When a visitor clicks the button, they enter their number and our system connects them to your agent instantly. This reduces friction, speeds up response time, improves lead conversion rates, and lowers call costs by automating the connection process.

WhatsApp marketing is the use of WhatsApp to send promotional messages, product updates, offers, and customer support communications to a large audience. Because WhatsApp is an internet-based messaging platform — not a telecom SMS channel — TRAI's DND rules do not apply to it. This means WhatsApp messages can reach customers who are registered on the DND list, making it a powerful complement to traditional bulk SMS campaigns.

Bulk SMS delivery is near-instant. Most messages are delivered within seconds of being sent, and the average recipient reads an SMS within one minute of receiving it. This makes bulk SMS ideal for time-sensitive campaigns such as flash sales, OTP delivery, appointment reminders, and emergency alerts. Our platform supports high-throughput delivery for millions of messages per day.

SMPP (Short Message Peer-to-Peer) is a protocol used for exchanging SMS messages between SMS peers, in particular between operators and businesses. It enables direct, high-speed, high-volume SMS delivery — often exceeding one million messages per hour. SMPP connectivity is used by enterprises, aggregators, and developers who need to integrate SMS sending directly into their own applications, CRMs, or platforms rather than using a web-based dashboard.

Yes. Our platform provides real-time delivery reports for every SMS campaign. You can see which messages were delivered, failed, or pending — broken down by recipient. Reports can be viewed on the dashboard and downloaded in CSV or Excel format. Daily, weekly, and monthly summary reports are also available to track campaign performance over time.

Missed-call verification is a simple and cost-free way to verify a user's phone number. The user places a missed call to a dedicated number — the call is automatically disconnected after one or two rings, and our system captures the caller's number and marks it as verified. It is free for the user (no call charges), works on all mobile networks, and is widely used for lead generation, opt-in confirmation, and lightweight two-factor authentication.

DTMF (Dual Tone Multi-Frequency) refers to the audio tones generated when you press keys on a phone keypad. Each key produces a unique combination of two frequencies that automated phone systems recognise. DTMF is the backbone of IVR systems — when you press "1" to select a language or "2" to check your balance, the system reads that DTMF tone. It is also used in call centre routing, banking phone menus, access control systems, and security verification.

Bulk email marketing is sending a single email campaign to a large list of subscribers simultaneously — used for newsletters, product launches, offers, and customer updates. It is highly effective for small businesses because it is low-cost, measurable, and allows precise targeting by segment. Our platform ensures 90%+ inbox delivery rates with spam-optimised sending infrastructure, detailed open and click tracking, and easy unsubscribe management to keep your list healthy.

Yes. Unlike the standard WhatsApp Business app, which is limited to a single device, the WhatsApp Business API allows multiple team members to access the same WhatsApp number from different devices and locations simultaneously. This is ideal for customer support teams, sales departments, and call centres that need to handle hundreds of conversations in parallel from a shared inbox.

If you attempt to send bulk SMS without DLT registration, telecom operators will block your messages and they will never reach recipients. TRAI made DLT registration mandatory in India for all businesses sending commercial SMS. Additionally, using an unregistered Sender ID or template can result in penalties. Meta Reach Marketing helps businesses complete the entire DLT registration process quickly — including entity registration, Sender ID approval, and template submission.

Yes. Our IVR systems support multiple Indian regional languages including Hindi, Tamil, Telugu, Kannada, Malayalam, Bengali, Marathi, Gujarati, and more. Businesses serving customers across different states can configure language-specific call flows so each caller hears prompts and responses in their preferred language, improving customer satisfaction and reducing call drop rates significantly.

Yes. WhatsApp Business API uses end-to-end encryption for all messages, meaning only the sender and the recipient can read the content. Additionally, businesses using the API are verified by Meta, so customers see a verified business name with a green tick badge — increasing trust. This makes the API suitable for sensitive communications such as OTP delivery, account alerts, payment confirmations, and healthcare notifications.
