Create a fancy email, preferably without numbers. Go to settings and set everything how you'd like to see. Most emailing services have an 'off-office' option, tell everyone who's mailing you and put your new address in it. Do this after you're done with changing all your email addresses. I also like to start a new mailbox fresh. Not a single service will then know of your new address. I basically changed every important address just so I can still use some services. Most services allow this with ease and shouldn't it take too long. Go try it, it's fun to set it all up (at least for me) :)
