social emails:

Filter them. I have email records of all FB messages, friend confirmations, etc. but they never hit my inbox

promotional email:

You're lumping everything together. Patio11's emails, which I signed up for and love reading, end up in the promotions tab.

Have you heard of 'permission marketing'? Every email I get from a business, I asked for. I WANT to see them.

If a business sends me too much, or stuff I don't want to see, I unsubscribe.

It sounds like you've signed up for a bunch of things you don't want, and haven't unsubscribed.
