Businesses are constantly seeking innovative ways to connect with their customers. The advent of mobile technology has opened up new avenues for communication, with push notifications and SMS (Short Message Service) messages leading the charge. But when it comes to choosing between these two, which one should businesses opt for? This article delves into the nuances of push notifications and SMS, helping you make an informed decision.

The Evolution of Customer Engagement

The integration of sophisticated notification systems and the strategic use of SMS messaging have emerged as game-changers in the transformation of customer engagement. These digital communication tools not only enhance user engagement but also offer significant cost advantages over traditional methods.

This shift underscores the critical need for e-commerce companies to embrace modern communication strategies. By leveraging the immediacy of push notifications and the universal reach of SMS, businesses can create more personalized and effective interactions with their customers. This approach not only keeps companies competitive in the bustling digital marketplace but also opens up new avenues for growth and customer loyalty.

Push Notifications: The In-App Innovator

Push notifications are short, pop-up messages sent by an app to a user’s device, even when the app is not actively in use. These notifications can include text, images, and even sounds, offering a rich media experience to engage users. They are designed to attract immediate attention and encourage users to take action, such as opening the app or completing a purchase.


  • High Visibility: Push notifications pop up directly on a user’s device screen, ensuring high visibility and immediate attention.
  • Rich Media: Unlike SMS, push notifications can include images, emojis, and buttons, providing a more engaging user experience.
  • Cost-Effective: Most push notification services offer scalable pricing plans, making them more cost-effective than SMS in many cases.
  • Personalization: With access to app usage data, push notifications can be highly personalized to the user’s behavior and preferences.


  • App Dependency: Push notifications only work if the user has installed your app and granted permission for notifications.
  • Overuse Risk: Excessive or irrelevant notifications can annoy users, leading to app uninstalls.
  • Platform Limitations: The character limit and design of push notifications can vary significantly between iOS and Android devices.

SMS Messages: The Ubiquitous Communicator

SMS messages are text messages sent directly to a user’s mobile phone number. They are one of the most widely used forms of communication, capable of reaching users across different devices and networks, without the need for an internet connection.


  • Universal Reach: SMS can reach any mobile phone, regardless of the device type, operating system, or internet connectivity.
  • High Open Rates: SMS messages boast an open rate of 98%, ensuring that your message is almost always seen.
  • Direct and Personal: SMS messages provide a direct line to your customer, allowing for personalized communication.
  • No App Required: Unlike push notifications, SMS doesn’t require the user to have a specific app installed.


  • Cost: SMS messages can be costly, especially at scale, as they often incur per-message charges.
  • Limited Content: SMS is restricted to text and a limited character count, offering less creative freedom compared to push notifications.
  • Regulation and Compliance: Businesses must navigate various regulations and obtain explicit consent to send SMS messages, reducing flexibility.

Choosing the Right Channel for Your Business

When deciding between push notifications and SMS, consider your business goals, target audience, and the nature of the messages you wish to send. Push notifications, with their rich media capabilities and cost-effectiveness, are ideal for engaging users within your app ecosystem, promoting offers, and providing timely updates. SMS, on the other hand, is unparalleled in reach and reliability, making it suitable for urgent communications, broad announcements, and reaching users outside of your app.

Return on investment (ROI)

When comparing the cost-effectiveness of push notifications versus SMS, push notifications clearly offer substantial cost savings. For instance, one client achieved monthly savings of $6,000 by opting for push notifications. Through the strategic use of 1,208,401 notifications over a six-month period, this retailer circumvented the costs typically incurred by SMS services, which would have amounted to over $36,000. This strategic choice translated into significant monthly cost savings.
