Do you use different emails and how do you organize them?

Also, do you use disposable emails? What for?

I have a lot of emails made with simple login and I use the same one only for three websites. Then I get all emails forwarded to the same email, and an email for personal use (family, work, friends...) also forwarded to that one. So something like this:

    
o  o  o     o  personal
 \ | /    /
   |    /
   |  /
   o
