Would you pay for an AI tool that writes cold emails tailored to each prospect? (not a pitch, genuinely asking)

Thinking of building a tool where you paste in a prospect’s name, company, and what you’re selling, and it generates a personalized cold email in seconds. Handles tone, subject line, CTA, the whole thing. It would also allow you to import spreadsheets and generate multiple cold emails at once and also connect to the users email to send these emails for them via a chrome extension Before I go further with it, I want to know if there’s actually demand.
