If you decide that you don’t need your Gmail account anymore, and you’re sure you won’t want your username in the future, you can simply close the account. Here’s how:
- Click Settings at the top of any Gmail page.
- Open the Accounts tab.
- Click Google Account settings.
- Click Delete Gmail Service along the left side.
- Enter all information in the appropriate fields, and check the box next to Yes, I want to remove Gmail from my account.
- Click Remove Gmail.
Once you close your Gmail account, you can’t reactivate it, and you won’t be able to retrieve any messages. After a certain period of time, Gmail recycles your username, so we can’t guarantee that it will be available if you decide to open another Gmail account.
