Built my first product in 6 hours - AI cold email generator

Hey IH community! Just launched my first ever product and honestly pretty nervous. I've worked in sales and freelancing where I wrote 20-30 cold emails daily. Each took 10-15 min to personalize. That's 5+ hours just writing emails. So I built an AI tool that generates personalized cold emails in 10 seconds. You input company name, recipient, your service and it creates a professional email in your chosen style. Started coding 6 hours ago. Used Python + Streamlit + OpenAI. Deployed on free hosting. Listed on Gumroad for $19. Current status: 0 customers, 0 marketing experience, just trying to get my first sale. Shipping fast is better than building perfect. Starting is scary but exciting. Would love brutal honest feedback. What would make you actually buy this? What's missing? Link: https://vitaliyaitools.gumroad.com/l/nhzqj Thanks for reading! This community inspired me to finally ship something.
