Here's a little exercise for you. For the next week or so, put all of your "authorized spam" (junk email really) in a mail folder. Put all of the hotel discount emails, car rental deal emails, web coupon emails, and any other regular to semi-regular commercial email into a folder.
The number of emails that you'll have at the end of the week might surprise you.
I'm certainly surprised by the number of emails that I receive from various companies and organizations. I never read those emails and they do have a tendency to clutter up my in-box. Which is a bother. A time waster. A violation of my sense of order.
So, I've given myself a little project for the next while. Every time I receive one of those emails, I squint my eyes as I scroll down to the bottom of the message to learn about how I can get myself off of the email list.
Then, I do it.
Of course, it's not as simple as that. Some of the unsubscribe options work rather well. One click (or two) and I'm done. In other cases, I have to dig up my login information for a site I've visited twice in the last five years so that I can hunt through the sub-menus for the place to unsubscribe myself. And the number of lists that I've somehow gotten myself on to amazes me!
