Before you delete Gmail from your Google Account, remember that you'll no longer be able to send, receive, or access email from your goreegoree2013@gmail.com account.
You also could lose access to services outside of Google where you use goreegoree2013@gmail.com. For example, if you use this email address as a recovery email for your bank account, you may have difficulty resetting your bank password. If you proceed, you'll need to update your email address everywhere you use it outside of Google.
When you delete Gmail, your mailbox will be closed, all of its contents will be permanently deleted, and you'll lose access to your email address within 2 business days.
