Unsubscribe link in entry notify email template

I'm trying to have a link in the blog entry notification email that unsubscribes the email recipient when the recipient clicks on the link. Similar to the behavior of the Subscribe Verify email template.

Here's the code I put in the Global Templates/Email Templates/Edit Template:

start code_____________

http://marilyns.nexcess.net/blog/mt-add-notify.cgi?__mode=unsubscribe&email=&magic=&blog_id=&redirect=&entry_id=

end code________________

The blog's web address is http://marilyns.nexcess.net. I tried the instead of http://marilyns.nexcess.net/blog/mt-add-notify.cgi but that didn't work either. Figured I'd try a direct url and script path.

All I get in the email template is this:

http://marilyns.nexcess.net/blog/mt-add-notify.cgi?__mode=unsubscribe&email=&magic=&blog_id=2

Which of course does not work.

Can someone tell me what I need to do have this template have the correct code to have an unsubscribe link?

Thank you!
