When push notifications fail to deliver, it can affect how many people see your message and click your affiliate link. A good first step is to check if users have unsubscribed or blocked notifications in their browser. This is normal over time, and most push platforms will stop sending to those users automatically. You should also look at whether your service is showing any technical errors, like browser compatibility or expired permissions. Some platforms give reports on delivery, so you can see how many actually went through. To improve future delivery, clean your list regularly by removing inactive users. Keeping your messages clear, helpful, and not too frequent can also reduce the chance of users blocking them. What’s worked well for others when messages don’t go through?
