Here you can set an impression target for your Cut-In, for example 1,000. If you set such a target, the Cut-In will be removed automatically after the cut-in has been played to 1,000 listeners, even if the "duration of integration" has not yet been reached.
Example:
You create a Cut-In with a duration of 30 days and an impression target of 1,000. The cut in is automatically removed once 1,000 listeners have been reached or after the 30 days have elapsed. Depending on which of the two events occurs first.
