What should I offer potential clients as a beginning copywriter with no experience? Copy for their website, emails, email automation? How should I start and what should I learn first?

Hey guys, just wrote my first every outreach. I have one I wrote myself, and then I asked chatgpt to make it better. A review would be appreciated https://docs.google.com/document/d/1jQ31r1r3X44tXgbqBPz3cDPa6igWcE0QF7oyux8u6OI/edit?usp=sharing

What would you guys say is the 80/20 rule for copywriting? Meaning: 20% of the actions lead to 80% of the results
