could you clarify what you mean by "mass marketing"?
In my experience, the best way is to approach agencies individually, and this means a targeted application to each one, if possible getting the name of the person you wish to contact, or at the very least writing to that agency and showing it is a targeted application, not simply "Dear Agency..."
Please forgive me if I have misunderstood your question.
My thoughts exactly. Put yourself into an agency shoes. Whom would you rather hire: someone who hired a marketing agency to send one hundred cookie-cutter letters, or someone who bothered to do the research and to send a personalized letter?
