Changing email for podcast correspondence?

Please include what your RSS Feed URL is

There is no email address anywhere in you feed, so the only contact address Apple have for you is the one you use as a login to iTunes.

Feeds can contain an 'itunes:email' tag containing an address they would use for contact, but yours does not have this tag. When you submitted the podcast you would have to have been signed into iTunes with your Apple ID, so the address which forms the ID would be the only one they would have to contact you by. If they are using a different address I can't say how they got it, unless you have it entered as an alternative address at http://appleid.apple.com

In any event it won't affect your submission, except that you won't hear about it when it's accepted or rejected (hopefully not the latter). However it will take some time after acceptance before you can find your podcast in the Search.

You say you received a notification - was this to your Apple ID address? Did it say they would be using a different address in future? (Obviously don't post either address here.)

It can take anything up to several weeks for a submission to be accepted - it just depends on how long a queue there is. If you're not getting the emails then all you can do is try the Search from time to time, but this can take some time after the podcast has actually appeared in the Store.

You could try emailing Support at podcasts 'at' apple.com and asking them to use the address you want. (Give them the feed URL.) I can't promis that they will take any notice.

Lower case throughout, otherwise yes.
