Collecting data through email

[emptiness]

Does anyone know a good way to collect data through email? I wanna send emails to my clients asking them to rate products and receive the answer trough email. But I don't want them to have to write. I tryed to achieve this building a form, but when answering, the form came empty.

I'm thinking about placing a link in the email body, but I really would like them not to have to open a new window.

Anyone have an idea?

Thanks a lot, as always.

Hi,
* Make a form over at youe site.
* open the page with IE.
* file> send> page by email.
with defaulth setup of outlook the email will show the form without having to open the attachment. At least that's what I think. If I am wrong, it won't be the first time:}
