Google Photos uses nostalgia with their push notifications to bring users back to the app
Google Photos is probably the most installed photo collection app in the world. In this example, they harness nostalgia to compel users to click through their push notification.
Why we think this push notification is good:
Nostalgia is a very powerful emotional trigger to compel user action. In this case, the notification feels like it’s an extension of the app, where the value of the app is actually viewing your photos from yesteryear. If you’ve received this notification, you might wonder what happened 4 years ago today and take a walk down memory lane from the photos you’ve taken around that time getting users to engage with the app more, if not on a daily basis with these push notifications.
