10,000 Unread Emails

This is the default home screen on my iPhone:

Each time someone sees my screen, they always make a comment on the number of unread emails, text messages, or missed calls. Most of these items show up on the notifications page, where I can see the first few lines of content. For Gmail, the count also includes the Social and Promotional inboxes, which I rarely check. I do not believe I have missed any important messages, even though the unread count is a bit ridiculous.
