Why do you want to do email marketing? Can your need be fulfilled by any other medium? Have you explored the other mediums? Are you supplementing your other medium with email or are you replacing it

Typical answers could be:

• I need to reach a large audience
• I need to reach my audience in a personalized manner
• I need to reach different kinds of an audience with different kinds of messages
• For the same needs, my other mediums are expensive and cannot be measured
• I am supplementing my field force efforts with this medium
