Dealing with code violations

[Lucas Howes]

I am trying to do some direct mail advertising with properties in my area. My area encompasses five cities that are pretty close to one another. I have gotten code violation lists from all of the cities. They are all in a different format, and NONE of them have a mailing address. How do I sent mail for these properties? Just send to the property itself? Its not really feasible to look up the mailing address of each property, as the list is too large. Was planning on doing postcards for them if that matters.
