Unsubscribe Mail Merge not working

Unsubscribe Mail Merge not working

Hi,

I'm creating a campaign and sent myself a test email.

The inserted the mail merge field '$[LI:UNSUBSCRIBE]$' at the bottom of the email.

However, in the test email, the link appears as 'http://zc1.maillist-manage.com/ua/testemail?&cmpDgs=1e10cd9f3f20b8e&tm=unsub'

How do I use the unsubscribe mail merge and identify how the link should appear?  Do I have to embed the code with special syntax through HTML?

Any advice or simple instruction set for including the mail merge fields would be helpful!

Thanks.
