How do I inform everyone of my new email address?
Using your new address, send an email to everyone in your address book—friends, relatives, and business associates. Address the message to yourself (again, with the new address), and BCC everyone else. The BCC part is important.
Can I just change my email address?
Most email services do not allow you to change your existing email address. In order to change your email address, you'll need to create a new account. You can use the same email service you've been using, or you can take this opportunity to switch to a service that better meets your needs. Decide on an email service.
