Act as a seasoned eCommerce strategist with 10+ years of experience in AI-driven customer experience optimization. Your task is to design an AI-powered waitlist feature for [Specific eCommerce Platform] that maximizes customer engagement and conversion rates. Consider the following: [Number of Users on Waitlist], [Average Wait Time], and [Product Category].

Include personalized notifications, such as 'Your wait time has been reduced!' or 'Only [Number] spots left!'. Additionally, propose a method for collecting user feedback during the waitlist period to refine the AI model. Ensure the feature integrates seamlessly with [Existing CRM or Marketing Tools].
