To find out the lifetime value of your push notification subscribers, start by checking how much money you earn from them over time. This means looking at how often they click your messages and how much they spend through your affiliate links. If you track your earnings and divide that by the number of subscribers, you’ll get an average value per subscriber. Then, think about how long people usually stay on your list before they unsubscribe or stop clicking. Multiply the average monthly earnings per subscriber by the number of months they stay active. This gives you a simple idea of what each subscriber is worth in the long run. It helps you decide how much you can spend to get new ones.
