An opt-in push notification is a type of mobile notification that requires the user’s explicit consent before being sent. This means that the user must actively choose to receive these notifications, typically by enabling them in their device’s settings or through a prompt within the app. Unlike traditional push notifications, which are automatically sent to all users, opt-in push notifications are targeted and personalized, delivering relevant and timely information to the user. This opt-in process ensures that users have control over the notifications they receive, creating a more positive and engaging user experience.
