We need to send SMS to a different audience every day.
We have created an import definition with mobile connect, and have used in automation studio with an Import Mobile contact activity. We have executed twice this automation, with different contacts form two days, and the list has collected all the contacts from these two execution.
But we need to have only contacts from each one, in each send.
Is there any way to remove contacts in a list in mobile connect?
Is there any way to overwrite the list?
Thank you all
