SMS notifications are automated text messages sent to mobile phones to deliver timely alerts, updates, and reminders directly to users' devices. Unlike marketing texts, SMS notifications are transactional messages triggered by specific events, offering immediate delivery with 98% open rates and reaching users without requiring internet connectivity or app installations.
It's no secret that businesses use multiple digital communication and marketing channels to reach their consumers. These communications solutions encompass a broad set of tools that help businesses engage with customers efficiently and reliably. Traditional marketing can be costly, and unless you have a large advertising budget, you likely need a less expensive way to get info into the hands of your consumers. That's where mobile messaging comes in. SMS messages are limited to 160 characters, so concise and clear communication is essential for effective messaging.
Mobile messaging tools like push notifications, iMessage, or SMS text messaging are all ways to reach your consumers in real-time. If you're looking for a less expensive option to connect with your audience and grow your business, SMS notifications may be the ticket.
Defining SMS Text Messaging
SMS is an abbreviation for Short Message Service, and it's what most of the modern mobile world uses to send text messages. SMS is widely used for delivering important notifications and updates. Mobile phones and tablets that are powered through a cellular network have the capability to send and receive SMS text messages. SMS messages can be sent using cellular data but cannot be sent using only Wi-Fi. A valid phone number is required to send and receive SMS messages.
Even iPhones will use SMS text messages when the user is trying to send a message to an Android device, with message bubbles turning green when the message is delivered through SMS or MMS (Multimedia Message Service). The message is considered received once it appears in the recipient's messaging app.
It's also worth knowing that SMS messaging can only include 160 text characters, and any photos, video, audio, or other rich media is sent as an MMS message. SMS notifications are commonly used for timely updates, alerts, and customer engagement across various industries.
SMS vs MMS vs RCS
Understanding the differences between messaging formats helps businesses choose the right approach:
SMS (Short Message Service):
- Text-only messages
- 160 character limit (standard encoding)
- Supported by all mobile devices
- Lowest cost per message
MMS (Multimedia Message Service):
- Supports images, videos, audio, GIFs
- Up to 1600 characters of text
- Requires data connection or MMS-capable plan
- Higher cost (typically 3x SMS)
- Not all phones support MMS
RCS (Rich Communication Services):
- Enhanced messaging with rich media
- Read receipts, typing indicators
- Interactive buttons and carousels
- Requires RCS-enabled device and carrier
- Limited adoption (primarily Android)
- Falls back to SMS if not supported
Business Recommendation: Stick with SMS for maximum reach and reliability. Use MMS selectively for high-value visual content when your audience demographics support it.
What Are SMS Notifications?
Now that we know what SMS text messaging is, let's take a closer look at SMS notifications.
SMS notifications are alerts that allow businesses to communicate with their audience. When an SMS text message is sent, it will appear directly on a user's mobile phone or device, with the user also seeing a notification. This notification can pop up in several places:
- Lock screen - Visible even when phone is locked
- Messaging application - Default SMS app (Messages, Samsung Messages, etc.)
- Notification center - Persists until dismissed
- Badge notification - Red dot on messaging app icon
This multi-layered visibility is why SMS notifications achieve such remarkable open rates—users encounter the message multiple times before even unlocking their device.
The SMS message and the notifications are sent directly to the user's mobile device, so you don't have to rely on them to check your app or visit your website. SMS notifications provide timely and important updates directly to the user's inbox, ensuring that critical information reaches the user quickly. Businesses must make sure users have opted in before sending messages. Users must opt-in to receive text messages, and the user can control where and when they receive notifications through the Settings app on their device. The number of messages sent can be tracked for effectiveness and compliance.
Key Characteristics of SMS Notifications
Direct Delivery:
SMS messages are delivered directly to users' mobile devices without requiring them to check an app, visit a website, or open their email. This immediacy makes SMS ideal for time-sensitive communications.
Universal Accessibility:
Unlike push notifications that require app installation or email that requires internet access, SMS works on any mobile device with cellular service—from the latest iPhone to basic feature phones. This makes SMS the most inclusive communication channel available.
Character Limitations:
Standard SMS messages are limited to 160 characters using standard encoding (GSM-7). Messages with special characters or emojis use Unicode encoding (UCS-2) and are limited to 70 characters. Longer messages are split into multiple SMS segments, with each segment charged separately.
Permission-Based:
Users must opt in to receive SMS notifications from businesses. This creates a high-intent audience—people who receive your SMS messages have explicitly chosen to hear from you, resulting in higher engagement rates compared to channels with passive opt-ins.
Two-Way Communication:
Unlike one-way broadcast channels, SMS enables two-way conversations. Users can reply to messages, making SMS ideal for customer service, appointment confirmations, and interactive campaigns.
SMS Notification Examples Across Industries
SMS notifications serve versatile use cases across different industries. Here are real-world examples demonstrating how businesses leverage SMS to improve customer experience and drive results.

When to Use SMS vs Push
When SMS is Superior:
- Time-critical alerts (OTP codes, fraud alerts)
- Transactional updates (shipping, appointments)
- Users without app installed
- Older demographics (higher SMS preference)
- Two-way conversations needed
- Guaranteed delivery critical
When Push is Superior:
- App engagement and retention

When to Use Both:
Most sophisticated notification strategies use both channels:
- Send initial push notification
- If not opened within 2 hours, send SMS backup
- Or: Send push for low-urgency, SMS for high-urgency
- Or: Let user choose preferred channel in settings
Why Are SMS Notifications Important?
SMS notifications are an important communication tool for sending real-time information to your internal teams or external audience. Here are just a few reasons why SMS notifications are important to growing your business.
Unmatched Open and Response Rates
- An estimated 7.5 billion people will own a mobile phone by 2025, with the United Nations predicting the global population reaching 8.5 billion by 2030.
- 98% of users open and read SMS notifications, meaning you're reaching more of your audience.
- Nearly 50% of users who react to a CTA after receiving an SMS notification will make a purchase.
- SMS messages have a 209% higher response rate than phone, email, and social marketing. It's easy to delete emails or have email messages go straight to spam, but SMS notifications are delivered directly to a personal device.
- The average user will respond to an SMS message within 90 seconds. Most people have their phones on them at all times, making it easier to read and respond to SMS notifications.
- SMS notifications also enhance customer service by enabling real-time communication and prompt responses, ensuring customers receive immediate support when needed.
Universal Reach and Accessibility
No App Required:
Unlike push notifications that require app installation (average app retention rate: 25% after 90 days), SMS works on any phone with cellular service, including feature phones used by billions globally.
Works Without Internet:
67% of mobile phone usage in developing markets occurs without reliable internet access. SMS works regardless of Wi-Fi or data availability, making it truly universal.
Cost-Effectiveness
Low Cost Per Message:
SMS costs $0.0075-$0.01 per message in the US, making it one of the most cost-effective marketing channels:
- Cost per thousand (CPM): $7.50-$10
- Email CPM: $2-$10 (but lower open/conversion rates)
- Facebook Ads CPM: $10-$30
- Google Ads CPC: $1-$5+ per click
High ROI:
SMS marketing delivers an average ROI of 4:1 to 10:1, depending on industry and implementation quality. For transactional SMS (order updates, appointments), ROI comes from reduced support costs and improved customer satisfaction rather than direct revenue.
SMS notifications are relevant to building a valuable relationship between your brand and your audience. What makes SMS notifications especially effective is their ability to deliver urgent, time sensitive communications that prompt quick action. Businesses can keep customers updated on their account status or order progress via SMS, ensuring they always have the latest information. Many companies send special offers and promotions via SMS to engage customers with exclusive deals. Restaurants and delivery services use SMS notifications to inform customers about deliveries, order confirmations, and status updates. The users receive personalized news, promotions, and purchase information in real-time, and in turn, your business sees an increase in engagement, traffic, and conversions!

How SMS Notifications Support Business Growth
With high open, read, and response rates, it's no wonder businesses utilize SMS marketing strategies. Many platforms are offering flexible SMS notification solutions as part of their customer engagement services.
Keep Costs Low
Unlike social media, you don't need a high ad budget for users to view your content. You also don't have to worry about sponsoring posts or fickle algorithms. Using mobile messaging like SMS to market your business keeps costs low while increasing your ROI. SMS notifications are a budget-friendly tool that will help grow your business.
Reach Your Target Audience
Over 6 billion people use mobile phones worldwide, and SMS messaging is the primary form of texting. This creates a massive opportunity to increase your reach with SMS messaging and notifications. Text messaging allows you to reach a more diverse audience as every age group and demographic uses it.
Create Engaging Content
SMS marketing requires users to willingly opt-in to receive messages; this means the user is interested in hearing from you. Irrelevant messaging can quickly have users opting out, so it's important to use this opportunity to create engaging, relevant, and personalized content. When users open a personalized product suggestion, reward, or coupon, they are more likely to engage with the CTA and make a purchase. Additionally, businesses can use SMS to inform customers about new features, which helps boost engagement and keeps customers updated.
Increase Brand Loyalty
There's something about SMS text messages that feel more personal than other communication platforms. Some businesses are scared off by this, but it is an opportunity for your brand to create a more humanized and emotional connection with your audience. Consumers are more likely to remain loyal to your brand if they view you as accessible. A dedicated customer base can increase overall engagement, brand-trust and be brand ambassadors by spreading positive reviews for your business.
Have a Multi-Channel Marketing Plan
It's crucial to utilize a multi-channel marketing plan. Having a user-friendly website and mobile app is the first step. Combining email marketing, push notifications, SMS messaging, and other marketing strategies will leave you set up for success across all channels.
Using a Notification Service
Leveraging a notification service can transform the way businesses communicate with their customers through SMS notifications. A notification service streamlines the process of sending SMS messages, managing contact lists, and tracking delivery status, all from a single platform. These services often offer advanced features like automation, message personalization, and detailed analytics, which help businesses optimize their SMS marketing campaigns and improve customer engagement. By using a notification service, businesses can save time, ensure messages are delivered efficiently, and maintain compliance with SMS marketing regulations. This not only enhances the effectiveness of SMS notifications but also ensures that customers receive timely, relevant, and well-crafted messages that drive engagement and build lasting relationships.
Choose What's Best For Your Business
Bottom line, SMS text messaging and notifications are beneficial tools for businesses to leverage for growth. They allow you to meet your consumers where they are and provide value and information in real-time. SMS notifications are one of the most reliable ways to reach customers.
There are different types of SMS communication: one way communication, which is ideal for sending appointment confirmations, reminders, and transactional alerts, and two way communication, which enables interactive exchanges such as customer feedback and support. Choosing the right way communication—whether one way or two way—is important to ensure your business meets its communication goals effectively.
Decision Framework
Start with SMS if you:
- Have time-sensitive communications (delivery updates, appointments)
- Need guaranteed message delivery
- Serve users who may not have your app installed
- Want to reduce no-shows or support inquiries
- Have budget for per-message costs
- Serve demographics that prefer SMS
Add SMS later if you:
- Are still building audience and don't have phone numbers
- Have low-urgency communications
- Primary audience uses your app actively
- Budget is constrained (start with free push notifications)
- Need to prove ROI before investing
Multi-Channel Strategy
The most sophisticated notification strategies don't choose between SMS and other channels—they use all channels intelligently based on context:
Example Strategy:
- High-Urgency Transactional (fraud alert): SMS + Push simultaneously
- Medium-Urgency Transactional (order shipped): Push first, SMS if not opened in 2 hours
- Low-Urgency Marketing (new feature): Push notification followed by email
- User Onboarding: In-app messages with push re-engagement
Platform Recommendation:
MagicBell provides unified multi-channel orchestration, allowing you to send notifications across SMS, push, email, in-app, Slack, manage user preferences by channel, implement intelligent fallback logic, and track engagement across all channels.
Getting Started
Step 1: Define Your Use Cases
List all communications you currently send and categorize by urgency, frequency, required action, and current channel.
Step 2: Map to Channels
- Critical urgency + time-sensitive action = SMS
- High urgency + app users = Push
- Medium urgency + detailed info = Email
- Low urgency + visual content = Push
Step 3: Start Small
Choose 2-3 high-impact use cases like appointment reminders, order shipping updates, or security alerts.
Step 4: Implement and Measure
Set up SMS with Twilio or MagicBell, implement tracking for all KPIs, run A/B tests on messaging, and calculate ROI after 30 days.
However, it's essential to know your audience and understand how each marketing tool works to know what's right for your business. With MagicBell's complete notification system, you can refine your communication strategy by notifying users wherever they are and on their preferred channels to boost engagement and retention.
