T2 implemented AI models to improve the efficiency of SMS targeting - the operator added predictive models based on big data, machine learning and artificial intelligence. As a result of the update, the average click-through rate of SMS campaigns increased from 3% to 7%, and the cost of attracting a customer dropped by more than half. Algorithms analyze hundreds of signals, including user preferences and the content of the advertising message, to more accurately select the audience. Currently, more than 120 ready-made segments are available to advertisers, and by the end of the year T2 plans to increase their number to 300. The main thing is that the AI does not find out about our purchases at three in the morning.
