Perfect Yellow Letter Recipe

[Tony Johnson]

What have you found has been the most effective mix of yellow letters, postcards, typed letters, etc. I sent out my first mailing and I'm looking into postcards on my next mailing but I want to know what has been effective on here. Also recently found about zip letters too. I'm focused on doing 7+ mailings to my list as well

I'm sorry Shane marketing is also a science.  

But I know this because of the numbers I keep and the experience of sending millions of letters out.  

Welcome to BP btw.
