Do not confuse "unix culture" of mostly plain text only email messages with "MS Junk" culture of overblown formatting with background images company logos as a few image files in every (internal) email.
"average size of an email worldwide"
The bulk of all email is personal, not corporate: think Gmail, Hotmail, Yahoo, the 50k ISPs worldwide, etc. Average all of that together with the corporate mail (small percentage), and you're well under 4KB per message, especially considering the amount of SMS gatewaying going on with smart phones today. Most of those are one liners with the smtp header being 4 times the size of the body, with total message size being under 1KB.
