Do you push to have as many sent electronically as possible?
I wish we lived in a world in which there was a secure electronic equivalent to document delivery. The technology exists, but nobody uses it.
As it is, the standard is for every company I deal with to require a separate login which gives me a web interface to tracking down the documents I need. Maybe they'll send a generic email when something new arrives. The problem is that this raises the convenience barrier so high that I rarely see the documents I'm being sent when they arrive — it happens when I'm already on the site and looking around. Which means I have to remember to go to the site.
When I get something in the mail, in contrast, I can look at it immediately, and then if necessary I can put it in a to-do box, which gives me a clear indication, in one place, of all the stuff I need to deal with.
