One of the biggest problems I have faced as a copywriter is finding clients with a "real" pre-qualified targeted list.

Copy well written and done works amazing if targeted right. Even the best copy in the world will fail miserably if the target is unqualified. I have seen letters sent out to 10 clients and pulled seven in. Profits were massive. I have seen letters sent out to 3,000 and not had one reply.

Ever tried selling a disabled bath to teenagers? Never, target is completely unqualified. What I want to know is this from you all...

How much time and effort do you put into targeting before you send out your list?
