In the email I'm writing there are three separate points. The last two ones are not so long so that each of them can fit in a single paragraph. However, the first one is needed to be split into two paragraphs. Because it's the most important point, I want to put it on top.
Q: How can I indicate that after finishing the first one, the second point is mentioned? Or, how to tell the reader that the third paragraph is not belonged to the first point?
I can explicitly say "as for point 2" at the beginning of the third paragraph, or simply divided the email into three sections with headings, but I want to find a subtler method to do that, for practicing writing skills purpose. I think the solution lies on the combination of white-space and punctuation.
