Direct Mail: To use or not use variable field data

[Graham Howell]

Ive got about 500 post cards in the hopper, ready to be sent out. They are (in my opinion) designed well, eye catching, and with a clear message. However, they do not contain any variable field data aka Dear "Mary" I would like to purchase your home at "123 Main St Small Town, Tn," they just simply state that I am looking to "purchase a home in your area." I had a fellow investor told me that the response rate for post cards without variable field data was much lower than those with it. Curious to know what everyone else's experience is and if I need to make changes to my post card before hitting the send button. 

Thanks!
