I've always wondered if Gmail and other free email services put a cap on how many emails you can send per day, and now I have my answer: 500.
Addicted as I am to digital communication, I can't really imagine needing to send that many emails, especially since I have instant messengers (where I probably do hit about 500 sent messages a day!), but it did get me thinking about how many emails I do send per day. With work email and personal email combined, I hit send an awful lot of times each day (though like I said, nowhere near 500). About how many emails do you send per day, and are you sending more for work or play?
