Segment evolution display how the count of the segment changes over time.
To see the evolution of a segment you need to enable this feature first. In any segment you create in Users -> Segments go to Evolution, click Enable, and it will take a while for data to be available.
How it works:
- every day, our system counts the recipients according to segment conditions and saves the value
- the value is displayed in a daily timeline and you simply see to the chart
