No matter how hard you try to keep them, some clients will still go. Can something be done to get them back?
The action of returning users is called retention, this is the task of a marketing expert and they do it well, but their success depends on the way they turn to them.
Our part of the work here is: applying algorithms that study the behavior and interactions of that user while it was active and finding the key details by which the marketing team can determine the optimal retention strategy for each user.
With good coordination with the marketing team, the number of re-activated users increases significantly.
