Instead of sending the updates to our mailboxes why don't you design a way to send them straight to our homepages? This will make access to them more relevant and immediate. Plus it will spare the email.
It'll be much better, something like facebook or twitter. We'd love to follow our friends and have all their feeds collect on our homepages. This way the homepage itself is going to be much more interactive, updated and with better use of the available space.
