When checking if a push notification campaign is successful, there are a few numbers to pay attention to. The open rate tells you how many people viewed your message. The click-through rate shows how many actually clicked the link. Then there's the conversion rate, which is how many took the final action, like buying a product or signing up. You should also keep an eye on unsubscribe rates. If many people leave your list, the message might be too frequent or not helpful. Looking at how much money the campaign made compared to what you spent can also help you see if it was worth it. These numbers can guide how you plan your next push campaign.
