Any words of advice on DBL. How to avoid it? What might I be doing wrong? Could it be my platform? I am mailing GI and constantly getting hit by DBL sometimes prior to even dropping. I am kind of new to mailing GI. I know this is happens and keeping off the DBL is very hard to do.. but I can't even get 100k messages out without getting hit. I clean my lists through Quickie first and then IW second.
