Every 12 minutes—that's how often Americans check their phones each day. It's no wonder brands that are focused on innovative marketing strategies give a lot of consideration to mobile marketing best practices.

Mobile push notifications are one of the most effective ways to encourage customers to engage on mobile. With the average user spending about 7 hours per day online, web push—the web-based counterpart to mobile push—is another effective "push channel," one that brands leverage to nudge customers to revisit their websites.

The brands behind the best push notification campaigns—whether sent via mobile or web—have a lot in common. They prime for push notifications. They use testing to find winning campaign variants faster. They use personalization, send-time optimization, and location marketing in creative ways. Without further ado, here they are—four of our favorite push notification campaigns.

3 Best Push Notification Campaigns
