can't delete my alternative email address (account is deleted) and I get a lot of mails when I download something from the store

For a while I used an alternative email address for my apple ID. A few months ago I deleted the email account and yesterday I wanted to delete it at the apple ID menu as well but it is still activated although its not listed at my other mails. How can I change this?

I don't want to receive that much mails when I download something from the app store but I don't know how to stop...I had an ipod touch 3g before and now have got an 5g...With the old one I never hat any problems

Thanks
