Imagine you have several really popular apps, and once you develop a new must-have application, of course you want to notify your users about it! Let’s consider that one of your users is really into your products, so he or she has 5 of your apps installed on a device. If you start promoting your new product with broadcast push notifications sent to each of your apps, this user will receive the same notification five times in a row. Just imagine how irritating it might be!
