4.4.4.2 - How to Use Push Segmentation (e.g., by viewed product) (Difficulty: Advanced | Path: Scale)

Imagine walking into a massive department store. You head straight for the camping gear, spend twenty minutes examining hiking boots, and then leave. Two minutes later, a store clerk runs out to the parking lot and shouts, "We have a great deal on lipstick!" You would likely be confused, annoyed, and unlikely to return. This is exactly what happens when you send a broadcast push notification to your entire subscriber list without regard for their specific interests. It is the digital equivalent of shouting irrelevant offers at people who have told you, through their behavior, exactly what they want.

Segmentation is the strategic antidote to this problem. It is the process of dividing your subscriber base into distinct groups—or segments—based on shared characteristics, behaviors, or interactions. While basic segmentation might look at geography or device type, advanced segmentation, which we are focusing on today, leverages user behavior. By tracking what products a user views, what categories they browse, and what they leave in their cart, you can construct a narrative about their intent. You stop being a broadcaster and start being a curator.

The difference in performance is not subtle; it is transformative. Generalized broadcasts often suffer from low click-through rates (CTR) and high opt-out rates because they are irrelevant to 90% of the audience. Conversely, behavioral segmentation allows you to send a message about "Hiking Boots" only to the people who looked at hiking boots in the last 30 days. This relevance creates a value exchange: the user tolerates the interruption of a notification because the content actually aids their shopping journey.
