Advise on putting together my first Direct Mail campaign

[Clark Cavaliere]

Hello BP,

I'm looking to do my first direct mailer. My main purpose is to create a deal machine for my own personal investments. I've found what I think is a good lead source that allows for creating a very specific list with categories, such as age, income, mortgage types, etc. I wanted to ask what types of mortgages (ARMS vs conventional vs mature) and demographics should I target to in order to have a higher response rate?
