I don’t understand your question. Can you be more specific about what you have in mind? What about the email docs is unclear to you?
p.s. Please do not re-post the same question in multiple places on the forum. That harms the organization of forum discussion and creates extra work for the folks volunteering to answer your questions. After your question is answered in one place, it still looks unanswered in another place, inducing someone to waste their time answering a question that has already been answered. (I will delete your posts in other places.)
