Notifications can guide users through key setup steps in onboarding, reward positive interactions, and encourage exploration. However, poorly designed notifications can be frustrating and lead to user abandonment. A well-designed notification strategy should extend the core product UX, consider user personas, goals, thoughts, feelings, potential pain points, channel usage, and areas of confusion. By creating a journey map, teams can identify blindspots in the user experience and implement targeted notifications that improve engagement and retention rates, such as 30% better retention for mobile apps with in-app messaging and 97% higher response rate compared to emails.
