Sending Emails to the Future

I've noticed that traffic is down of late and attribute this to the lack of new content during the day, when most people are online. Is there some way for me to send a postponed email message to Blogger's post by email function so new content can be posted while I am at work? If it helps, I use Gmail for my primary email but also have a Yahoo address, Outlook 2000 installed, and an old McKenna.edu email account.
