Post cards

[Sergio Sifuentes]

Hello BP community,

I'm having hard time finding deals in a consistent way. I don't have a system and I'm planning on setting it up. 

Question is: Once you have your target defined (your zip code for example) how do you get a whole of all of the different addresses? I need them in order to mail all the letters.  

And one more question is there any preference between Post cards and yellow letter? Which one is better and why?

I will highly appreciate your feedback

Thanks!

Sergio.
