cfmail question

I hope someone can help me with this. I'm kind of stuck on the conditional.

I have a newsletter signup form that includes a check box that is check by default.

<label for="mailList"><input checked="checked" id="mailList" name="mailList" tabindex="14" type="checkbox" value="0" width="5px" /><span class="checkbox">I would like to receive your e-newsletter.</span></label>

I'm trying to email the answer, yes or no, based on whether or not the box is checked. Here is the conditional code between my <cfmail></cfmail> tags.

Subscribe to e-newsletter? <cfif isDefined("form.mailList") AND Len(form.mailList)><cfif NOT Compare(#form.mailList#,"0")>yes<cfelse>no</cfif></cfif>

If someone checks the box I get the sentence "Subscribe to e-newsletter? Yes" in an email. If someone does not check the box I get "Subscribe to e-newsletter?" I can't figure out how to get the "No" to show up in the email when the box is not checked.

I feal like I'm close here but just can't seem to get the "No" answer emailed when the box is not checked.

Thanks a lot for your help!!
