You can create a C# class assembly and create a smartobject where you can serialize the context browser field into the smartobject. Use that smartobject in the email wizzard. It's a three step process. I can guide you if you need help. I spend lots of time working on the HTML formatted email and it worked like a charm.

I really have no idea how to create C# assembly class, if you could guide me, it will really helpful.
