When you create a new Gmail account, you will be sent a congratulatory email from Google confirming that your account has been successfully set up.

It is vital that you do not delete this email. Please record the exact date and time that this email was sent to you and if possible, forward this welcome email to a secondary email account as a backup.

If you ever get locked out of your Gmail account, this one bit of seemingly unimportant information, is vitally important in helping you to recover your account!
