The email is for changing your AOL username account (without the @aol.com), the account that you are logging in with using your AOL email address is not affected.
If you don't have any purchases and/or a balance on your AOL username account then you don't have to do anything, in a couple of days the account will disappear. If you do and you want to continue to have access to it then you need to convert it to use an email address (which can't currently being used as an account's primary email address) within the next couple of days, which you can do via your computer's iTunes : Convert your AOL Username to an Apple ID - Apple Support
