Never pay an agent an up-front fee. That is not how literary agent representation works. Agents earn a commission only after they've landed a publishing deal for you. Also, agents scarcely ever contact writers. If an agent that you haven't queried contacts you about representation, be suspicious. Look up the agent and check if the email address is correct for that agent/agency.
