As I've gotten older I've accumulated more e-mail addresses.<p>Then it comes time to sign up for a new service and I never really know which email address to use.<p>Like when do you use a personal email addy, when do you use a school one, a work one?<p>Do you have a "spam" address? Do you ever use it?
I try to have no more than four addresses going at a time:<p>1. Work<p>2. Friends, family, and signing up for free services that I want to identify myself with<p>3. Commercial transactions (anybody who has my credit card)<p>4. Anonymous address (which I use with websites that require signup but I feel have no business asking me). I personally use my real identity online for historical reasons, but if I didn't, I'd use this one.<p>[Edit: to answer your other question, they all get spam]
I just use one gmail account. Any other email account I just forward. Eventually everyone just emails to that one account since I always reply from it. It's not a problem at all.<p>With filters, using the +blah functionality (email+spam@gmail.com for example), it works great! Never need anything else.
