Direct mail - to land owners?

[Bab Adetiba]

I’m considering sending out direct mail yellow letters to a list of addresses . This time, The list is comprised of land owners. All less than 10,000 ft.² zones single family. I mostly hear of direct mail for properties but I want to target these specific individuals who own land. I do not wholesale; the purpose would be to spec build . Any experience with targeting land owners? Is this what people already do and I’m late to the game? Are the motivations the same for land vs property owner? Lastly, I was advised by a builder to not inform owners I will be building a house. Apparently they don’t like that - not sure. Any tips with language ? Thanks.
