Unread Emails

How many emails received in your mailbox daily? I have lost count how many email I received daily. I usually would clear them everyday so that my mailbox would not full of unread mail. There was some day I went to travel and did not check mail for three days, my mailbox had at least 300 unread emails on the time I log on to the mailbox. oh my... that took me more than a hour to go through all the email and more than 2/3 emails were spam emails. haii
