What happens when you ask someone to email you, but you don't send them an email first?

Then I might not see their message for a day or so, unless I'm actively checking more frequently for it, or unless I add them to my addressbook ahead of time.

That's why my rule doesn't put it in the junk folder. I put it in a sub-folder of the inbox so that it is easily seen.
