Northern Trail Outfitters (NTO) rolled out a global SMS initiative three months ago, as their customers have shown great interest in receiving promotions via text. However, NTO was notified they are already at 75% utilization for their annual Super Messages.
Why could this be the case?
The rapid consumption of Super Messages could be due to a multiplier applied to each SMS message based on the destination country. This multiplier can vary depending on factors such as the destination country and the type of message being sent, leading to higher utilization of Super Messages than anticipated.
