Whether you go with Coffeecup or some other software, avoid site builders included with hosting packages and on-line subscriptions. You'll be stuck having to rebuild your site if you change plans/hosts. Better to own your own software and have full control of your site no matter where you host it.
Excellent point. I already have a hosting provider, though.
The CC Form Builder can take care of your email situation: http://www.coffeecup.com/mailchimp/
One question: I have almost 900 email addresses that I maintain in my Outlook client. I could dump those into a csv file to export. Would Mailchimp allow such importing?
Thanks!
