strategy for selling organically

I am affiliated with a product and this is my strategy to sell it. I'm promoting a seduction ebook as an affiliate and I'm using the following strategy: I managed to join the WhatsApp group of a very famous influencer who makes videos and also has a course on seduction. What I did was steal this influencer's leads. Everyone who is already in the group knows that it teaches seduction so the leads are already warmed up I got around 700 leads I copied everyone's number into a notepad and I'm sending messages to these leads I used GPT chat to generate a script I analyzed it and I tested it and it seems to be generating good results I have sent messages so far to around 50 leads and some of them seemed interested in my offer I would like to know from more experienced people if this is a good strategy and what I could improve to get more results
