Which of the following is NOT an application of AI in marketing?

In considering the applications of AI in marketing, it's important to recognize how each option aligns with marketing strategies and practices. Customer segmentation, predictive analytics, and chatbots are all directly relevant to marketing functions.

Customer segmentation utilizes AI to analyze consumer data, allowing marketers to identify distinct groups within their audience based on behaviors, preferences, or demographics. This helps tailor marketing strategies to different segments for more effective campaigns.

Predictive analytics leverages AI to anticipate future consumer behaviors based on historical data. This application aids marketers in making strategic decisions about inventory, promotions, and targeting efforts, enhancing campaign effectiveness and resource allocation.

Chatbots are increasingly utilized in marketing to provide customer support and engage users on digital platforms. They offer quick responses to inquiries, enhancing customer experience and driving conversions effectively.

In contrast, while email spam filtering employs AI to identify and filter out unwanted emails, it operates outside the specific realm of marketing functions. It does not directly contribute to marketing strategies or customer engagement in the same way the other options do, making it the correct choice as it is not an application of AI in a marketing context.
