Email sequence about let's say a shop that sells energy drinks?An online shop or retailer. How would you approach that, can't seem to find any examples of physical products being sold.

Hello i have a question, 1.Could you look for people and offer them to improve their overall look and fell of the site where you would change their about page add some character to their site with copywriting? 2.As well how do you outreach,what do you actually offer if you wanna offer them a landing page email? Bassicly what I'm looking is more ways to copywrite for customers. Do people pay for making better copywrites for their products,for about us pages or is it ussualy tied to email marketing? Where can we find a example of a sequence email that is being sent to customers when they sign up for news letters? Hope this makes sense. Thank you.
