Marketing and Lead generation

[Norm Chrostowski]

When marketing and doing direct mail what's the best avenue to take? Meaning should I use companies like list source or listability? Or should you use companies that specialize in lead generation? Like leadknack? from what I've read a lot of these lists have been used over and over again. Owners are getting bombarded with the same flyers or postcards. Thoughts or any advice is greatly appreciated. Thanks, Norm
