Notifications Exposed: Marketing's 'Spam Everyone!' Meets Engineering's 'Check Permissions First' in a Food Delivery Tango

The notification system is a complex process that bridges the gap between marketing and engineering teams. Marketing teams aim to send messages, increase brand recall, and encourage user engagement, while engineering teams focus on reliability, scale, and control. A notification service acts as a mediator, ensuring that messages are delivered efficiently and effectively. Using a food delivery example, the process involves the order service triggering a notification, which is then processed by the notification service, considering factors such as user login status, notification preferences, and device type. The message is then personalized and delivered through various channels, including push notifications, email, and SMS. The system tracks user engagement, providing valuable feedback to marketing, engineering, and product teams, enabling them to refine their strategies and build stronger relationships with users. By understanding the intricacies of notification systems, companies can create more effective and user-friendly experiences, ultimately driving business growth and customer loyalty.
