Marketing Campaign Automation

A mid-sized e-commerce company wanted to improve engagement for their weekly promotional emails. By connecting ChatGPT-5 to Gmail, the AI could analyze past email interactions, open rates, and click patterns for each subscriber. Using this data, ChatGPT-5 suggested personalized follow-up emails tailored to user behavior, such as recommending products related to past purchases or sending reminder emails for abandoned carts.
