Direct mail campaign for vacant lots

[Lance Wakefield]

Has anyone ever done a direct mail campaign to vacant lots rather than houses? I dable in building houses and am looking for lots in a specific area I have the list of lots in the area and will be starting the campaign soon. I am curious if anyone has done it before and if they have had success. I am also curious what one might say to the sellers when they do call! haha. Does anyone have any advice ideas or experience to share? 

Thanks!
