How to Write Less, Say More

I have a rule of thumb that when I send an email, I make sure that if it’s viewed on a smartphone, you can get through it in a few swipes of your thumb.  In my experience, if it’s longer, people start assuming, “Wow, this is a book.  I’ll read this later.”  And how often do they actually return to finish reading your tome?  Not often.  That’s one reason that so many emails fall through the cracks.
