Dear /COMPANY NAME/,
My name is /YOUR NAME/, from a YouTube channel /CHANNEL NAME/.
I’m writing to you because it has been a while since I’ve been using your product/services. I absolutely love it, and I think it would be a perfect fit for my audience as well.
Are you open to chat for 15 minutes about a potential sponsorship?
