Setting up automated push notifications is a great way to build interest before a product launch. Start by choosing a push notification service that offers automation. Most of them let you create a series of messages and schedule when each one goes out. For example, you can send one message three days before the launch, another one the day before, and one more on the launch day. You just write each message and set the timing. This helps keep your audience updated without sending everything at once. Try to plan the sequence so each message shares something useful or exciting. A countdown or special bonus can also help build more interest. What other ideas have people used in their launch sequences?
