The difference comes down to timing and value. A helpful notification tells you something you want to know, like when your food delivery is arriving or when someone replies to your message. But notifications become annoying when they are too frequent or just trying to pull you back into an app for no real reason. Many apps send reminders or promotions that have nothing to do with what you care about, and that feels like spam. The best notifications are personal and relevant to what someone is already doing or waiting for. What kind of notifications do you think cross the line from helpful to annoying?
