The usual failure
Everyone gets the same campaign because segmentation felt like a data project. Best buyers get the same 15% as people who bought once in 2022.
What to make true
Recency, frequency, monetary as a simple grid. Mail the living. Sunset the dead. Protect the people who already pay you.
Worked example
Keep it this plain. A team uses rfm as if buying the software installed the meaning. It did not. Everyone gets the same campaign because segmentation felt like a data project. Best buyers get the same 15% as people who bought once in 2022. The move is not a new integration. Recency, frequency, monetary as a simple grid. Mail the living. Sunset the dead. Protect the people who already pay you.
