Push Notifications are brief and delivered immediately, so make sure you use the best combination of title, image, and message to make the most out of it. A/B Testing allows you to create two variations of your notification with a different image, title, or message. After that, help you see which notification is doing better from a subset of your subscribers, and push it to the rest, leading to more conversion as well as revenue. With every test, you better know your audience and enhance your notification strategy.
