Deleting a Gmail account is permanent. After going through the process, all of your emails and account settings will be erased. You will no longer be able to use your Gmail address to send or receive emails, and the address will not be made available for anyone else to use in the future.
To delete a person’s old email address, in Mail go to ‘Window’ menu and ‘Previous Recipients’. Then click on the old email address and press the ‘Remove from List’ button. You should do this anytime someone sends you a ‘my email address has changed’ email.
Create a new email address If you want to change your email address, sign up for a new address. After you sign up for a new address, you can transfer emails and contacts from your old address to the new one. If you believe someone created a Gmail address using your trademarked name, contact them to resolve the issue.
