Notifications are a crucial component of most products, but users want to control their notification experience. Notification preferences allow users to configure how and when they receive notifications. It's essential for users to have control over both the notification logic and channels used. This balance is necessary to avoid user frustration and increase productivity. Providing users with notification preference management can delight customers and create a positive differentiation from competitors. Implementing advanced settings, such as redirecting notifications to another user, silencing notifications at night, or using multiple email addresses, can enhance the user experience.
