there, while editing a post, i'm trying to insert

hi there,
while editing a post, i'm trying to insert 'subscribe by email' at the bottom of the post. however, when i save the post and go to it, the subscribe by email option appears at the very top.
am i missing something obvious? i thought that i can insert the shortcode in any place in my post and it'd appear there but it doesn't seem to work that way..

any ideas?
thanks,
Adam
