Why do push notifications make users delete apps?
Because permission is borrowed, not owned. A notification interrupts someone's day, and the interruption is judged in a second: is this for me or for them. Marketing dressed as urgency spends trust the product worked to earn. Notifications about the user's own things, their result, their order, their streak, earn their place. Enough withdrawals, and users remove the app's voice entirely.
The delete rarely happens in the app. It happens on the lock screen, at the third interruption that served the sender.
Permission is a loan. The user grants a channel into their pocket. Every notification is a withdrawal or a deposit. Their thing arriving: deposit. Your campaign: withdrawal.
The one-second judgment. Lock screen reading is triage. For me, or for them. The answer is decided by the first four words. Write those four words for the reader, not the metric.
Urgency is a finite resource. Cry wolf twice and even real urgency gets swiped away. Save the loud channel for things that are genuinely about now.
Frequency caps protect you from yourself. The growth dashboard rewards one more send. The user's patience does not. Set the cap where the user would set it, then send one less.
Ask late, ask in context, and take the no gracefully. A user who declined notifications and stayed is worth more than one who accepted and left.
Loss aversion cuts both ways here. You fear losing reach. The user fears losing quiet. The user wins, because the delete button is theirs.
Speak when it is theirs. Stay silent when it is yours. That is the entire rule.
