I have a resource for direct mail copywriting that doesn't have any examples of email letters, only postal letters, and I'm wondering how to refurbish this product to make it more appealing when few people are actually sending postal letters (even though they should).

Should I:

* update it by adding examples of email letters
* argue more forcefully and explicitly for the timeless nature of classic direct mail and that it still works today when people try it
* just market it to those who already understand the classic potential of direct mail (and who would such folks be?)

Thanks for your insights. If you'd like to see my pitch for this product, it's at http://www.yudkin.com/scourse.htm . I sell some copies of this, but not as much as I'd like.
