Personalization is a key element to effective push notifications. By using information about your audience's preferences and behavior, you can send notifications that are more relevant and likely to be acted upon. One way to personalize notifications is to use the recipient's first name or location. You can also use their past purchases or browsing history to suggest products or services that might interest them. According to a survey by SmarterHQ, 72% of consumers will only engage with personalized messaging.
