To change your email address for Gmail please follow these steps:

1. Sign in to your AdSense account at www.google.com/adsense
2. Select the My Account tab
3. Check the Login Information section at the top of the page. Do you see an edit in Google Accounts link?
- Yes. In this case, you're using a Google Account. Click the link and update your login through the Google Accounts site. Please be aware that if your Google Account is a Gmail address, you will not be able to change it at this time.
- No. You're not using a Google Account, so you can select a new login by linking your AdSense account to a Google Account. While still logged in to AdSense, visit https://www.google.com/adsense/migrate-login-1 and follow the instructions to update your login. Please note that if your desired email login is associated with another AdSense account, you will not be able to update your AdSense login to the same email address. This would include previously disapproved, closed, or pending AdSense applications. If this is the case, we kindly ask that you use a different email address.

HotMail, Yahoo and other free mail services are not provide way to change an email address due to security purposes. so you can not change email address.but you can create a new account with a new name ..

AOL, MSN other large ISPs which offers pay services they often have such flexibility.for more you can check in account settings there you must get option to change email address and password ..
