I've found that sending emails when you know they'll be at work (so they'll notice it) is tremendously useful -- say 9am, 2pm, 5pm. People will tend to answer immediately incoming messages before a long queue of messages from the previous day that need attention.
A little shameless self-promotion, that's exactly one of the use-cases we envisioned for our company's product, Momentomail ( http://www.momentomail.com ).
My co-founder and I actually do this with each other, schedule messages so they'll be received sometime in the morning when we're both likely to be working through our mail queue from the end of the day and night before.
