From a test I did, your text box for the email address appears to be 
working. I can't offer advice on the processing of the user's input 
because you are using a ColdFusion page as the post action and I'm 
unqualified with ColdFusion. I think 25 characters for the email address 
is too small. I think you need to allow for up to 50 characters.

Be sure to offer an unsubscribe newsletter option.
