Direct Mail Campaign Advice

[Randall Kates]

Hey Everyone,

I'm looking for  some  different strategies.  When doing your  direct mail campaigns to your target houses i.e sending cards,mailers, letters  etc home. How long of  a duration is   recommended to wait before sending mail and doing your  next wave of  marketing i.e second or third round of letters? Also  how  many rounds  does  it take  until you  come to the  realization that you need to move on to another list?
