I need to change my email in the account.

Please be informed that the email of your account can be changed only by your manager and only after having verified your ownership of the account. You can verify your ownership by providing your manager with guest access to your Google Analytics, or by creating a test page with the MGID logo on it.
If you wish to keep the email, but you want to make sure that another user can visit your account, please read about it here.

In order to change your email, please contact your manager.
