link in my jmail

Hey there I have a jmail that I use how I wish to also send a link in the email so that when it is recieved that person can go and check there order

at the moment it stands as is
    JMail.Body = JMail.Body & \"Order Nummer: <a href=admin_wine_show_order.asp?tracking=\" & strOrder_nummer & \">Go To Order</a> \" & VbCrLf

the problem is that when the email is sent it gets sent as a text string and nor a link
I have heard you can use JMail.HTML ???
is this correct or does anybody have a good idea :)
