Sending real-time notifications to the user's device window can ensure timely communication of their subscription status. This can be a more effective method than relying solely on email or platform- based messages, especially for users who may not frequently check those channels. Employing push notifications can help to elevate the urgency and visibility of such messages, thereby improving user awareness and engagement. Furthermore, with the increasing number of OTT services available, users may be subscribed to multiple services at once, making it even more challenging to keep track of when each subscription is due for renewal.
