Introduction
If you’re using SMS to communicate with prospects and customers, it’s important to know about the two main SMS traffic types: marketing vs. useful messaging. “Marketing messages” are often designed to sell a product or service, while “useful messages” provide crucial information or offer time-sensitive assistance. There are rules and best practices that apply differently to each type of message, and mistakes can be costly. But, if you follow some basics, your company can be confident about using SMS for marketing as well as useful messaging.
TL;DR: SMS traffic includes both marketing messages (promotions, sales, event invites) and useful messages (notifications, reminders, support info). Each has its own regulations, with marketing SMS requiring explicit consent and stricter rules, while useful messages still require permission but are less regulated. Following best practices for opt-in/opt-out, clarity, and privacy helps maintain compliance, build trust, and improve customer engagement.
What is SMS Traffic?
SMS traffic is the volume of text messages (SMS) transmitted over a network during a specific period, including both person-to-person (P2P) messages and application-to-person (A2P) messages like marketing alerts, verification codes, or notifications.
It’s tracked by mobile carriers, businesses, and marketers to measure usage, manage network load, bill for services, and monitor for unusual spikes that could indicate spam or fraud.
SMS Marketing Regulations Are a Good Thing
Following SMS marketing regulations is crucial because compliance to best practices not only keeps your sends legal, but also helps you build trust with your customers. Here are a few things to keep in mind about regulations when crafting your SMS marketing strategy.
- Make sure you understand the local regulations for SMS marketing in each country where you plan to operate.
- Follow best practices for opt-in and opt-out messaging, and make it easy for customers to unsubscribe from your messages.
- Respect customer privacy, and never sell or share their personal information without their permission.
- Use clear, concise, and accurate messaging in your SMS campaigns.
Following regulations can shape your brand reputation, helping to be seen as a trustworthy and knowledgeable company. Plus, when you contact customers in a way they enjoy, they are more likely to continue the relationship with your business and refer you to others. Be sure to always respect the customer’s ability to give consent, empowering them to make their own purchasing decisions.
Different Types of SMS Messages
The most important rule for SMS marketing is to provide value. If your message does not offer something interesting or important, it will be ignored and deleted by customers inundated with notifications from their smartphones every day. Check out some of our favorite SMS marketing examples. There are two main types of SMS messages.
Marketing SMS
Marketing messages should never feel like spam. Rather, they should always have a purpose or benefit. This could be anything from a sale or promotion to new product information or an event invitation. Marketing messages should be clear, concise, and accurate. Remember that customers are more likely to take action if they understand the message immediately.
Useful SMS
On the other hand, “useful messages” are not for the purpose of selling something, or inspiring a conversion. In the context of SMS traffic types, useful messages provide information, offer assistance, or answer crucial customer questions. For example, a company could send out a reminder that their systems will upgrade over the weekend, and provide a link to connect with support for any questions. This type of message would be considered “useful” because it has relevant business value for the recipient. You can think of useful messages as crucial notifications, as opposed to a promotion of any kind.
Are SMS Traffic Types Regulated Differently?
The regulations for marketing vs. useful messaging vary slightly, so it’s important to be aware of the differences in definitions and the laws that apply to each message your company intends to share.
Regulations around consent for SMS marketing can vary from country to country. For example, in the United States, SMS marketing is considered a form of “telemarketing” and is subject to certain regulations laid out by the Federal Trade Commission (FTC).
The FTC has specific rules about how consumers can opt in and out of receiving SMS messages from businesses, including requirements that companies include certain information in their messages. The main idea is to ensure you’re informing the customer, and setting proper expectations.
Under the guidelines, expressed consent must be obtained before beginning marketing messages, even if you already have consent to send useful messages. For the average company using SMS, this means getting permission from the lead or customer before sending them any type of message, and making sure they can easily unsubscribe.
Useful messages, on the other hand, are not as strictly regulated because they are not promotional in nature. However, they do require consent from the customer prior to sending any messages. When a customer opts in to receive updates on their purchase, or appointment for example, they have provided consent.
If a company then strays from useful messaging into a promotional message of any kind, they have violated regulations. It’s important to remember that useful messaging applies to one particular event or instance, it is not a blanket consent. Ensuring your business follows these stipulations can help to avoid any punishment or fines for subverting SMS regulations.

What if I send marketing SMS through one department and useful SMS through another?
Many organizations use useful SMS more on the product and customer service side, and marketing SMS for, well, marketing. It’s helpful to convene an SMS committee, or have someone who can be aware of the movements on both sides, so the company can present a smooth user experience and remain compliant to SMS marketing regulations as well as expectations for useful messaging.

Marketing SMS aims to drive sales or engagement and is subject to stricter regulations requiring explicit consent, while useful SMS focuses on delivering important, non-promotional information and carries fewer restrictions.
Understanding the difference—and following opt-in/opt-out, consent, and privacy best practices—helps businesses avoid costly mistakes, maintain compliance across regions, and create positive customer experiences. A strategic approach ensures SMS remains a trusted and effective communication channel for both marketing and service updates.
