Yes, this is a pain when using the direct email submit function. However, I have been able to get mine to format nicely and show up in the proper size and spacing. Here are a few things I had to adjust:
1) If you have sections, you need a full line break between them, otherwise they get out of alignment and sometimes overlap.
2) To keep sections and/or tables from extending the full width of your screen in the email, you need to change the sizes from 100% to some pre-set pixel width. With tables in sections, you have to do both settings, not just one.
