Advantages and Disadvantages of Promotional SMS

Short Message Service (SMS) advertising can be a powerful marketing tool, but like all marketing channels, it has benefits and drawbacks.

The following are some of the main benefits and drawbacks of promotional SMS:

Advantages

• High open rates: Since most people read their text messages within a few minutes of receiving them, promotional SMS messages typically have a high open rate
• Cost-effective: Promotional SMS can be comparatively cheap when compared to other marketing channels like print or TV advertising, making it an affordable choice for small and medium-sized businesses.
• High response rates: Since promotional SMS messages are frequently time-sensitive, they can persuade recipients to act right away, like buying a product or signing up for a service
• Personalizable: To make promotional SMS messages more interesting and pertinent, you can add the recipient’s name, location, or other pertinent information.n

Disadvantages

• Message length restriction: Since promotional SMS messages are only allowed to contain 160 characters, it can be difficult to communicate a complex idea or a lot of information
• Opt-in requirement: Promotional SMS messages are subject to opt-in requirements, so businesses must obtain customers’ permission before sending messages. This can shrink the size of the target market.
• Spam complaints: If recipients feel they are receiving an excessive number of promotional messages or messages that are irrelevant to them, they may mark SMS messages as spam. This may result in fines and harm to the sender’s reputation.
• Mobile device restrictions: Not all mobile devices can receive SMS messages, which might make it more difficult to reach some target audiences

Overall, when used effectively, promotional SMS can be a potent marketing tool, but it’s important to weigh the benefits and drawbacks before developing a strategy that works for your business’s goals and target audience.

Transactional SMS

Transactional SMS is text that clients or users receive from businesses or service providers informing them of critical or urgent information relating to a transaction they have already started.

These alerts are frequently triggered by specific occurrences or actions, such as a customer placing an order, making a purchase, or changing their password.

Unlike promotional SMS, which is used to advertise products or services to a large audience, transactional SMS is used to send transaction-related information to a specific person or group of people.

Since transactional SMS is frequently sent from a business or service provider to a customer’s mobile device, they must abide by specific privacy and security rules and guidelines. These messages are frequently sent directly to their phone with high deliverability and open rates. Nowadays, many communication platforms are integrating this SMS feature.

1. The following industries/businesses would benefit from using transactional SMS

‍

• E-commerce: Confirm orders, provide shipping updates, and notify customers of any changes to their orders

• CComp iant Specific privacy and security-related laws and regulations apply to transactional SMS, which enables businesses to send secure and compliant messages.

4. Disadvantages of transactional SMS

• Limited marketing potential: Because transactional is intended to provide transaction-related information, it is not appropriate for marketing or promotional activities
• Opt-in requirements: While explicit marketing consent is not required, businesses must ensure they have a valid reason to send these messages based on a prior transaction
• Short message length: Only 160 characters are allowed in transactional SMS messages, making it difficult to fit all the required information in a single message
• Only available on mobile: Transactional SMS can only be accessed by mobile phone users, which may limit reach to customers who do not use mobile devices

In general, businesses that want to provide customers with urgent and important information about a transaction or service may find that transactional SMS can be a useful communication tool, often alongside the implementation of a WhatsApp Business Suite solution for more dynamic and interactive messaging. 

OTP SMS

OTP SMS stands for One-Time Password SMS. It is a form of transactional SMS that is used to send a unique and temporary password or code to a user’s mobile device. Online banking, account login, and other verification and authentication processes all frequently use OTP SMS.

When a user requests an OTP, a unique password or code is generated and sent via SMS to the user’s mobile device. By entering the OTP into the required field on the website or app, the user then completes the verification or authentication process.

Because OTPs are temporary and can only be used once, they provide an additional layer of security and aid in preventing unauthorized access to user accounts.

OTP SMS typically has a short expiration time that can range from a few minutes to several hours, depending on the specific use case. The likelihood of the OTP being intercepted or used maliciously is decreased as a result.

1. Advantages of OTP SMS

• Security: OTP SMS adds a layer of defense for user accounts and transactions, making it more difficult for unauthorized users to gain access
• Convenience: OTP SMS is a convenient way to verify and authenticate users without the need for additional hardware or software
• Cost-effective: OTP SMS is a cheap way to provide users with one-time passwords or codes.
• Versatility: OTP SMS can be used for a wide range of operations, including online banking, e-commerce, and account login procedures

2. Disadvantages of OTP SMS

• Short lifespan: OTP SMS has a short expiration time, which can create inconvenience for users if they do not enter the code promptly
• Dependence on mobile networks: OTP SMS depends on the availability and dependability of mobile networks, which can be impacted by factors like network congestion or poor signal quality
• Limited reach: OTP SMS can only be accessed by people who have mobile phones and can receive SMS messages
• Security concerns: Phishing attacks, SIM swap fraud, and other forms of social engineering are security risks to which OTP SMS is susceptible.

Overall, the high open and deliverability rates ensure the user gets the password or code for OTP SMS as soon as possible. OTP SMS is delivered straight to the user’s cell phone.

3. Suitable businesses for using OTP SMS

‍

• Banking and financial services: Authenticate transactions, verify user accounts, and prevent fraud
• E-commerce: Authenticate logins and transactions to prevent fraudulent activities like credit card fraud
• Healthcare: Verify user identities to protect sensitive patient data in portals and apps
• Government agencies: Authenticate users for access to services and prevent identity theft
• Travel and hospitality: Authenticate reservations and payments
• Education: Authenticate users for online exams, assessments, and student portals

Overall, any business that needs secure and practical verification or authentication of user accounts, transactions, or sensitive information may benefit from using OTP SMS.

Compliance and Regulatory Guidelines

When sending any type of business SMS, you must adhere to regional regulations to avoid significant penalties and maintain customer trust. Here are the key guidelines to be aware of.

1. TRAI (India)

The Telecom Regulatory Authority of India (TRAI) requires all businesses to register on a Distributed Ledger Technology (DLT) platform. You must register your business, headers (Sender IDs), and message templates before sending any SMS to customers in India. Promotional messages also have strict sending time windows, typically between 9 AM and 9 PM. For more details, refer to the official TRAI website.

2. TCPA (United States)

The Telephone Consumer Protection Act (TCPA) governs telemarketing calls and texts. You must obtain "express written consent" from users before sending them promotional SMS messages. This consent must be clear and conspicuous. Transactional messages have less stringent consent requirements but must be directly related to a transaction or service. Learn more at the FCC's TCPA guide.

3. GDPR (European Union)

The General Data Protection Regulation (GDPR) protects the data and privacy of individuals in the EU. For sending promotional SMS, you need explicit, unambiguous consent that is freely given and can be easily withdrawn. The purpose of the messaging must be clearly stated at the time of opt-in. Non-compliance can result in severe fines. Review the official GDPR text for comprehensive rules.

How to Choose the Right SMS Type: A Checklist

Use this simple checklist to determine which SMS category fits your needs:

• Is the primary goal to market or sell a product/service?
  
  • If yes, use Promotional SMS. Ensure you have explicit opt-in consent and respect sending time restrictions.
• Is the message triggered by a customer's action (e.g., a purchase, password reset)?
  
  • If yes, and the content is purely informational, use Transactional SMS.
• Is the message for user verification, login, or transaction approval?
  
  • If yes, and it contains a unique, time-sensitive code, use OTP SMS.
• Does the message contain any offers, discounts, or marketing language?
  
  • If yes, it must be sent as a Promotional SMS, even if it is combined with transactional information.

In conclusion, the mobile-friendly world, the demand for personalized and real-time communication, the cost-effectiveness of SMS messaging, and the high open rates of SMS messages all contribute to the growing need for SMS as a communication channel for businesses.

SMS messaging will be a crucial business communication channel as companies continue to adjust to shifting customer needs and preferences.
