One tactic I use for opening emails is to write the question or point in the subject line (e.g. not "Meeting" but "Today's meeting is at 10:00 in 94a").

For the majority of situations this means easier comprehension/scanning and zero redundancy. It also provides good practice for anything that needs more than a single line.

For longer emails I also like to put a summary at the top, then an expanded details below as necessary, and make sure each paragraph starts a new point or item.
