Resource Drain: Managing numerous small segments requires more time and effort, which can be a substantial drain on resources. Message Dilution: When segments are too specific, the number of subscribers in each segment might be so small that your message loses its impact. Complexity: Overly complex segmentation can make it difficult to create and manage campaigns effectively. Data Overload: Too much segmentation can lead to an overwhelming amount of data, making it hard to derive actionable insights.
