How to Leverage SMS Marketing for Business

by Nov 1, 2022Bulk SMS

SMS marketing for business has emerged as a pivotal component of effective multi-channel marketing, as many brands actively reach out to mobile customers. Some businesses may mistakenly assume that SMS marketing requires substantial financial resources and lacks the capacity for personalized and targeted messaging while also lacking comprehensive analytical tools to measure return on investment.

Businesses frequently misunderstand mobile marketing, assuming it demands significant investments in mobile apps. Furthermore, there is a misconception that mobile marketing hinders personalized, targeted communication and lacks robust analytical capabilities to substantiate return on investment.

In reality, mobile communications are much more straightforward than commonly believed. Sending personalized and targeted text messages to mobile consumers is a simple process, and many businesses have already harnessed these advantages successfully.

Sending personalized and targeted text messages to mobile consumers is a straightforward process. Numerous businesses have recognized and enjoyed the advantages of using bulk SMS marketing to enhance their business communication.

However, only a few businesses have fully harnessed the true potential of SMS marketing. Until recently, SMS usage was predominantly limited to personal conversations, with businesses recognizing its significance in their marketing strategy only as smartphone usage experienced a sharp increase.

Conversely, marketing your business demands a significant investment of time and resources. Moreover, achieving success and gaining traction in your marketing endeavors can be challenging, primarily due to frequent social media algorithm updates and the overwhelming daily emails people receive.

SMS marketing, or text message marketing, is a straightforward method for your business to connect with customers and achieve a more substantial return on investment (ROI). Additionally, this approach is likely to be well-received by your customers.

So what is enterprise SMS marketing, and how is it beneficial for Indian businesses?

What are the benefits offered by it for Indian businesses? This blog post will provide answers to these and will guide you on SMS marketing for business in India.


What is SMS Marketing?

SMS marketing for business is strategy that involves sending promotional offers, deals, and transactional information to customers via text messages. This approach fosters one-to-one communication between businesses and their customers, allowing for direct and personalized interactions.

Automated text messages can target a large audience, reaching hundreds or thousands of customers simultaneously.

Indeed, SMS marketing, also known as mass text messaging, involves sending automated messages targeted to hundreds or even thousands of customers at once.

SMS marketing for business is highly effective, comparable to social media marketing, enabling businesses to engage with potential customers in real-time. Moreover, it is often considered more robust and reliable than email marketing.

SMS marketing relies on a database containing customer details, such as names, phone numbers, locations, and other relevant information, which allows businesses to convey their messages more effectively. 

A crucial aspect of this marketing approach is the ability to target a specific audience. Like Facebook ads, SMS marketing for business targets an audience segmented by criteria like location, age, interests, and more, ensuring that messages reach customers where they spend a significant amount of time: on their smartphones.

For businesses considering SMS marketing for their products or services, it’s essential to remember that it should be integrated into their overall marketing strategy. Additionally, businesses should refrain from launching SMS marketing campaigns without a well-defined plan outlining how to reach new customers and achieve their goals. 

Proper planning and integration with the broader marketing approach are key to the success of SMS marketing for business.

SMS marketing for business serves various purposes, such as informing customers about delivery status, sending supportive messages after app downloads, providing transactional updates following purchases, or simply sharing information about exclusive discounts and offers. 

However, the effectiveness of an SMS campaign is realized when a customer recognizes or is familiar with the brand. If the text message isn’t perceived as valuable or useful, it may be regarded as spam by the recipient.

Types of SMS

The most cost-effective and productive method for boosting your company’s profitability and maintaining a presence in the market is through bulk SMS marketing. This approach involves sending many SMS messages to numerous mobile customers.

SMS marketing is currently one of the most popular marketing tools, with various types of bulk SMS categorized according to their intended use cases. Here’s a brief overview of these categories.

1. Promotional SMS

Promotional SMS messages are designed to promote or sell products, goods, or services to individuals who are not yet customers. These messages are sent to recipients after preferences and consent have been verified, and they typically feature a six-digit numeric header, as permitted for your business by the DLT (Distributed Ledger Technology). 

Here are a few examples of how promotional SMS can be employed:

  1. Promotion of brand awareness
  2. Launch of a new brand
  3. Marketing of products
  4. Events
  5. Offers and discounts for sales
  6. Sales follow-up

  16. DND Filtering automatically
  17. SMS API integration with existing applications, websites, or software
  18. The SMS can be sent from 10 AM to 9 PM
  19. SMS gateways are robust and dynamic

2. Transactional SMS

Transactional messages encompass any message that contains a One-Time Password (OTP) necessary to finalize a banking transaction initiated by a bank or financial institution. This applies to all types of banks, including national, scheduled, private, government-owned, and multinational banks. 

These messages are critical for enhancing the security and integrity of financial transactions and are standard practice in the banking industry.

A transactional SMS is used for SMS marketing to send the information needed to use a product or service. You can use transactional SMS in the following situations:

  • Notifications regarding credit card purchases or account status
  • E-commerce alerts, such as order status, shipment status, and delivery details
  • Status of the PNR
  • Alerts/notifications from educational institutions to parents and guardians
  • Employer notifications/alerts to employees
  • Validation codes and registration codes
  • Information about OTPs and tracking

3. Service Implicit SMS

Service implicit SMS messages deliver essential information to registered customers, including OTPs, booking confirmations, and order alerts. These messages are sent to all recipients, even those who may have opted for “Do Not Disturb” (DND) status, as they are considered service-related and not promotional. They can be dispatched around the clock, 24×7, and typically feature a six-character alphabetic header approved by DLT (Distributed Ledger Technology). 

Here are a few examples of service-implicit SMS:

  • Net-banking confirmations and credit/debit card transactions.
  • E-commerce website confirmation of purchase, delivery status, etc.
  • To complete a payment, customers pay through a mobile app or website using a payment wallet. A one-time password is sent to complete the transaction.
  • Authentication requirements for e-commerce website, app, social networking logins, Demat account operations, KYC, eWallet registration, etc.
  • TSP/ISP messages.
  • Contains periodic information regarding balance, bill generation, bill dispatch, reminders about due dates, and confirmation of recharges (DTH, cable, prepaid electricity, etc.)
  • Periodic upgrades, notifications, and updates.
  • Retail stores may send messages about your bill, warranty, and school attendance.
  • Registration, appointment, discharge, and reports from hospitals, clinics, pharmacies, radiologists, and pathologists.
  • App-based confirmation messages.
  • Mandatory messages from the government, DOT, and TRAI.
  • Up-to-date information about car workshops, repair shops, and gadget repair centers.
  • Yellow Pages, Just Dial, and other directory services.
  • Securities and Demat account holders are alerted about day-end and month-end settlements.

4. Service Explicit SMS

Service-explicit SMS messages update customers about new offers, discounts, or service-related updates. These bulk SMS explicit messages are sent to customers only after obtaining their consent, and a stringent verification process ensures that recipients have given explicit permission to receive such messages. These communications also record future similar messages to maintain compliance with recipient preferences. 

Additionally, the brand name of the registered principal entity must be present in the message body, and a six-character alpha header is typically used to send service explicit SMS via DLT (Distributed Ledger Technology) platforms. This approach ensures that customers receive relevant and authorized promotional content while upholding transparency and compliance with regulations.

5. Unicode

It’s common for customers to prefer receiving messages in their language for a more personalized experience. Messages can be sent in languages other than English using Unicode, allowing for the use of various scripts and characters to accommodate the linguistic preferences of a diverse customer base. This enables businesses to effectively reach and engage customers in their preferred languages, enhancing the overall communication experience.

When sending SMS messages in non-standard languages like Chinese, Cyrillic, Arabic, Thai, and regional languages such as Hindi, Kannada, Marathi, etc., it’s essential to utilize the Unicode standard. 

Unicode assigns a unique number to each character, including non-Latin alphabetic characters. This ensures the text can be accurately represented and displayed in the recipient’s language, regardless of the script or characters used. Using Unicode is crucial for maintaining the integrity and readability of text messages in diverse linguistic contexts.

In SMS messaging, the standard character limit is typically 160 characters. However, when using Unicode to accommodate various characters, the character limit is reduced to 70. If a message surpasses this character limit, it will be segmented into multiple messages to ensure that all the content is delivered to the recipient while adhering to the limitations imposed by Unicode encoding. 

This segmentation ensures that the message is received accurately, albeit in separate parts, when it includes non-Latin characters or falls outside the standard character limits.

This type of SMS, which utilizes Unicode encoding, also supports the sending of emojis. Emojis, previously not easily recognized by the GSM 7 encoding standard, can now be handled effectively. It eliminates the necessity for encoding various protocols when using different languages or characters, making the process more straightforward and user-friendly.

6. Two-Way SMS

This type of SMS utilizes a dedicated virtual SMS number, allowing you to receive SMS messages from customers and respond based on the content of those messages. The replies received can be conveniently stored in inboxes or accessed through APIs, making it easy for businesses to manage and respond to customer inquiries and interactions effectively.

Using a dedicated virtual SMS number in this particular SMS setup, you can receive text messages from customers and subsequently craft responses based on the content of these messages. Responses can be stored in inboxes or processed through APIs, or they can even be forwarded to email.

Providing two-way SMS service for SMS marketing guarantees that clients can obtain immediate responses to their SMS inquiries. Responses can be archived in inboxes and processed through APIs, and they can also be routed to a specified email address. For receiving real-time SMS responses, both short codes and long codes should be employed.

7. Long Code SMS

A long code is a ten-digit virtual mobile number that serves the purpose of facilitating two-way communication. The sole expense of long codes is a modest SMS fee, as these services are available globally. Long codes can be categorized into two distinct groups.

  • Dedicated Long Code – Each client is assigned a unique long code, which is only used for their applications. It is possible to include unlimited keywords and applications with Office24by7.

Short codes are paired with specific keywords. Each short code number is associated with a particular keyword. When customers send SMS messages with that keyword, an automated pre-set response is dispatched. Additionally, custom responses can be generated and sent through URL forwarding.

You can access data related to the keywords and sub-words you utilize, the mobile numbers of customers, and the timestamps and locations of messages sent through your specific short code. Short codes come in two varieties:

Dedicated Short Codes: These codes are exclusively assigned to a single client’s business, serving only that particular business.

TRAI New Rules for Bulk SMS

Register as an Entity and Telemarketer

All businesses (principal entities) and bulk SMS service providers (telemarketers) must now register with telecom operators to send messages to their customers. Business firms were not required to register with TRAI before the registration. However, with the new rules, service providers and companies that want to send SMS to their clients must register with their respective telecom operators.

Registration of Headers and Templates

Sender ID is now known as headers, and each header must be approved and registered with the Telecom Operators.

The telecom operators must also approve each SMS or template directly. Bulk SMS service providers will no longer control sender ID and template approval, and all header and template details will be available to view on a panel.

Type of SMS

Previously, there were two ways to send SMS – transactional and promotional. However, TRAI has introduced three new routes in the latest update: Transactional, Promotional, and Service (implicit and explicit).

Under the new regulations, banks can send only OTPs via the transactional route, while service-related informative messages shall fall into the implicit category. It will fall under the explicit category if a customer has agreed to receive promotional SMS from a company. Only DND numbers will receive promotional SMS messages, such as offers and discounts.

Consent from Customers

The new regulation grants mobile subscribers (customers) to have their consent to receive messages, and it also gives them the ability to opt out of this in the future. On a single dashboard, they will be able to see the consents they have given and manage them as well as withdraw them at any time.

Preferences of the Customer

Customers previously had only the option of DND or non-DND. As part of the new rules, mobile subscribers have been provided with a time window in which to manage their preferences based on a specific time or day, and they are allowed to receive certain kinds of promotional messages regardless of their preferences. 

The customer can still receive messages even if he has activated DND on his number text from a company if he wishes to. The customer can also choose when to receive promotional texts.

Message Scrubbing

With scrubbing, it is now possible to ensure that messages are sent according to the customer’s specifications. It will filter the number of messages based on the customer’s criteria in real time. Real-time filtering of customer preferences results in immediate feedback.

Customer Complaints Management

Customers who believe their preferences or consent has been violated can register complaints via various channels, such as phone calls or SMS, to increase safety and authenticity in the system.

Telecom Interoperability

Telecom service providers can view details related to entities, telemarketers, headers, templates, etc., on the platform. Businesses and bulk SMS service providers can share their data with the network. This information can be viewed at any time.


All transactions are traceable using distributed ledger technology (DLT). The result is that all data is recorded and shared on the network, and it can be tracked at any time.

Error Codes in Bulk SMS

Any time there is an error in sending an SMS, a number will be sent out. Sending a message is not always successful due to SMS error codes. When a message fails to arrive, senders receive different error codes.  

SMS errors due to DLT scrubbing are delineated in detail for our customers in every outbound SMS. It will help you to understand the root cause of failure and troubleshoot issues with outbound SMS delivery right away with these detailed error codes. They relate only to DLT scrubbing issues.

Benefits of Using SMS Marketing

Bulk SMS marketing for business has been around for a while, and the ease of use has made it very popular these days. It offers many useful benefits to businesses in increasing their potential success and sales and gaining more loyal customers. Below are the many benefits of it in detail. Have a closer look at them now.

No Need for Internet

SMS marketing for business does not require the Internet. Even if you do not have an internet connection, there would be no problem using it. It is adaptable to every mobile phone in the world. It allows you to engage offline customers, those who do not use a desktop or laptop, or even those who do not use smartphones.

Amongst the high percentage of customers who use mobile phones and smartphones in both developed and developing countries, it is very successful. This means you can reach a wide audience with SMS easily.

As a result of this benefit offered, it increases the chances of you gaining more loyal customers or gaining people who would be keen on knowing about your products or services.

Mobile Friendly

Nowadays, it is very important to have a mobile-friendly business as more and more customers have become mobile-savvy. You can easily target this audience with SMS marketing that is not only mobile-friendly but also a strong asset to your marketing strategy.

Gone are the days when businesses give mobile-friendliness a last priority. Since mobiles are here to stay, their huge potential can be tapped fruitfully. This kind of marketing is possible for every kind of mobile phone. When appropriate links are shared through SMS, you can generate the right traffic for your business. Make sure these links are kept short. For example, if you offer a discount on a certain product or service, your SMS message should contain the link to this product or service.   

High Delivery Rate

An important aspect of SMS marketing is sending the text to the right audience. Ideally, the higher the connection rates, the higher the level of profitability for a business.

The rate at which messages are delivered to recipients, known as SMS deliverability, is high for it (which is almost 98%). This signifies that a very high number of text messages are sent to the customers. Thus, it can be said that it is the most reliable method of communication.

Further, it should be remembered that the success of an SMS campaign depends on the delivery rate. Successful SMS campaigns also mean non-spammy and valuable texts. Apart from the high delivery rate provided by SMS marketing, 90% of the SMSs are opened and read within three minutes of receiving them. Compared to all other channels, the click-through and engagement levels are more effective with SMSs.

Time-Efficient and Easy Scheduling

With SMS marketing for business, you can save a lot of time. It allows you to send SMS campaigns instantly. Very little time is required to create a text message that you want to send to people. Text messages can be sent to your customers when your business offers discounts or deals about products and services. Also, text messaging hardly takes a few seconds compared to phone calls and emails that take more than a few minutes.

As it is time-efficient, the entire process of SMS campaigning is highly cost-effective.  Moreover, since a lot of time and money is saved through it, your ROI is also increased. This holds even if there is low customer response.

It also allows the scheduling of text messages. You can also use the most successful SMS campaigns as templates for future purposes, which also help save your precious time.

Pocket Friendly

SMS marketing for business is very affordable, and even small businesses can benefit from using it.  Compared to other forms of advertising like billboards, advertisements, etc, it is more than ten times cheaper.

Regardless of the number of messages you wish to send customers, it is affordable and pocket-friendly. This proves that it is very attractive for those businesses, especially those who do not have huge budgets. It yields positive results even if your budget is very low and makes your brand presence felt by many customers.
