Propstream: Avoiding Duplicates

[Bryan Igboke]

I know propstream will not allow you to pull a property twice within the same list, which is great. Though, when I pull 2 separate lists in a similar area there is a chance that the property shows up on both lists. I also have the list automator and know that it can show you whenever a property appears on multiple lists, campaigns, etc.

My question is if there is a way that I can know that a property is a duplicate before I actually pull it. I ask this because my plan is to market to 10,000 new contacts per month, but last time I pulled 2 separate lists and many on the 2nd list were duplicates so I only ended up marketing to around 7,000 contacts. I just want to find a way to know if I am about to pull a duplicate that I already have the information for so I don't waste one of my 10,000 contacts per month on it. Please let me know if this makes sense and if there are any solutions / workarounds you guys know of!
