Do the first chats yourself before you automate anything, you can't script what you haven't learned makes a fan buy. Keep AI for rewrites and tone, not full auto; a flat bot reply kills a warm chat faster than a slow one. Build a small swipe file, openers, soft upsell, hard upsell, reactivation, and a clean "no money right now" path, then keep short notes on each fan so every reply sounds like you actually remember them.
Honestly though, chatting isn't your first problem if you're broke and just starting. Perfect scripts on an empty inbox earn nothing. The real lever early is traffic, getting the right people in front of the page at all. Sort that first, keep the chat human, and the scripts basically write themselves once you can see what real buyers respond to.
