Notification system

​​The right messaging is crucial to business success in today's fast-evolving digital landscape. Modern-day customers expect businesses to engage with them with the right message at the right time on their preferred platform. Businesses that successfully meet these expectations experience higher retention and customer loyalty. Various studies confirm this trend too.

  • A research study by Podium shows that 90% of customers prefer interacting with a brand. 

  • Another report from OneSignal confirms that brands using notifications for intelligent delivery of messages in preferred time zones and channels experienced a 28% boost in engagement compared to those that don't.

This guide provides a detailed step-by-step tutorial on how to build a customer notification system without any coding.  

Why customer notification systems matter: The hidden story 

Most companies make the mistake of creating a notification system from scratch, only to realize later the futility of their entire endeavor. Here is a reality check if you are looking to build a notification system:

  • It's more than a one-and-done task: Developing a notification system is just the beginning. You can't simply trigger notifications and forget; you must ensure the right messages reach the right people at the right time.  

  • Maintenance can feel like a marathon: Notifications aren't just a matter of pressing the send button. It requires continuous optimization. 

  • The troubleshooting challenges: Glitches are an unavoidable reality in the world of technology. You should be able to identify and troubleshoot the bugs as and when they appear.  

  • The ‘unsubscribe' conundrum: It's a tricky aspect. If users continue to find your messages irrelevant, they won't hesitate a second to hit the unsubscribe button. Therefore, the challenge is to build a system that does not let them go off the hook.

Simply put, developing a communication engine or a notification engine is just the starting point; the real challenge lies in sustaining it to the point where it captures user interest. That's the hidden story behind notifications

How to build a notification system?

Notifications keep customers updated with the latest information and events, ensuring they remain engaged with your brand. To stay ahead in today's competitive market, building an efficient notification system is essential.

What determines a notifications’ success?

The success of a notification relies on several key factors.

  • Relevance is crucial—notifications should be timely and tailored to customer preferences.

  • Timing is crucial because sending notifications when audience engagement is highest boosts their engagement.

  • Lastly, clarity is essential. Ensure that each message clearly communicates its intent, reducing ambiguity that can lead to confusion or customer dissatisfaction.

Notification system: Critical features  

A customer notification system simplifies the process of sending, tracking, and handling notifications through SMS and Email channels, empowering product engineering teams to design, build, and implement a feature-rich notification system.   

Framework for a notification system

Some of the prominent features of a customer notification system include:

  • Multi-channel support: It's the backbone of any customer notification system. A robust system allows you to reach customers through various channels, including email, SMS, WhatsApp, push notifications, and in-app messages.

  • Integration: It enables hassle-free and fast integration of the notification system into your app or website and other third-party software.      

  • Message templates: Since every messaging channel has unique content requirements, the notification software system should offer a wide range of templates for consistent and branded notifications.

  • Trigger-based notifications: Implement notifications based on specific user actions, such as order confirmation, OTP validation or other account-related activities.  

  • Multiple use cases: A customer notification system should cater to specific use cases, including reminders, alerts, feedback, two-way notification, authentication, support, and marketing.  

  • Segmentation: Segment your customer base according to your marketing campaign requirements to reach targeted customers and increase messaging relevance.  

  • Message personalization: It allows you to create and send personalized communication notifications with user-specific information, enhancing customer engagement.

  • Customization: It allows you to customize almost everything - the content, templates, features, layout, timing, and notification triggers. 

  • Automation: This feature enables you to set up automated communication workflows for various use cases and scenarios, such as sending order confirmations or password reset emails.

  • Message scheduling: Schedule notifications for specific events, dates, and times to deliver timely messages.

  • Real-time updates: Send near-real-time notifications, such as SMS, Emails, WhatsApp, or Push notifications, for highly time-sensitive events and emergencies.   

  • Analytics and reporting: Track key performance metrics with comprehensive analytics and reporting features.

  • Security and compliance: Since customer notifications deal with sensitive user data, they should protect sensitive customer data and ensure compliance with global and local data protection regulations, such as GDPR or HIPAA. 

  • Scalability: A notification system should be able to handle varying load levels with an increasing customer base and business growth. It should be able to send messages without causing delays or overloading the system.  

Customer notification system: Challenges galore

Though customer notifications have a proven track record of boosting engagements, customers have diverse preferences for communication channels. Email, WhatsApp, web notifications, in-app messaging, SMS, and cross-platform mobile push notifications have set standard user expectations. Some savvy customers even prefer to receive notifications on Slack. 

This is where the need to conduct a reality check arises:

  • Keeping customers engaged through all touch points is a monumental task, especially if it is not your engineering team's core competency. 

  • Developing a full-stack customer notification system from scratch may pose a formidable challenge for the product team. It involves navigating complex issues like scalability, workflow automation, and many more tasks. These complexities often translate into time-consuming implementation and integration processes. 

  • As the notification management system grows in complexity with the expansion of the user base, maintenance and upgrade costs increase significantly. 

Examples of good and bad notification experiences

Customer notifications can make a significant impact on customer experience. Effective notifications foster trust, while poorly executed ones lead to dissatisfaction. Here are some examples:

Example 1: Promotional push notification

A well-crafted promotional push notification is one that targets specific customer needs. For instance, a bank might send a push notification to customers who frequently use credit cards, offering them a tailored loan product based on their spending patterns. This kind of enterprise notification system ensures customers receive relevant and valuable offers.

A poor example is a bank sending push notifications about irrelevant offers, such as home loans to college students. Such notifications cause customers to ignore future communications, damaging trust.

Example 2: Promotional SMS

A good example of a promotional SMS in fintech is one that informs customers about new features that align with their interests. For instance, a fintech app might notify users of a new savings feature through an SMS that explains its benefits and how to use it. Such customer notifications help customers make the most of the app's features.

A bad example is an SMS blast about new services that aren't personalized. If customers receive frequent SMS messages about irrelevant services, they're more likely to unsubscribe.

Example 3: Transactional SMS

An effective transactional SMS in BFSI is one that promptly alerts customers about critical actions. For instance, if there's a suspicious login attempt on their account, an SMS can notify customers immediately, allowing them to secure their account. This type of customer notification system helps prevent fraud and builds customer trust.

A poor example is a transactional SMS that lacks essential details or uses confusing language. For example, an SMS that simply states "Transaction Alert" without specifying the transaction type or amount leaves customers unsure of what to do next.
