Until the campaign starts, the number of message recipients may still change. Let’s say that one of the criteria of your Campaigns definition is the blank phone number field, if your users fill it out before the campaign starts, they may drop out, reducing the number of users they reach. But it can also be the case that you currently promote the app particularly well and thus more, new users, fit into the target group. The number of users reached can thus increase.
