Listsource 40% Bad Data?

[James Ritter]

I just called Listsource to ask about how often they update their data and I was told that for real estate it will not be older than 6 months. That sounded good to me. However, I also asked what percentage should I expect to be bad data. I was told that it could be FORTY PERCENT. That sounds incredibly high to me.

Can somebody please give me an idea of how their experience went with using listsource for direct mail. Idea on bad data percentage? 40% seems like the list would be completely worthless.

Previously I have used Listsource and was pleased.  I used them in November and got some bad results.  I put in a search criteria for absentee owners and when I examined my list closer the property address and mailing address were the same.  I wrote them to ask how this could be considered absentee,  Their response was that is how the county sent them to us.  I asked for a redo and they would not give it to me stating it was not their fault.  I have bought previous list from them and never had this problem.  I argued that this does not qualify as an absentee owner list.  They claim that different addresses is not reliable and that they also look at "Homeowner Exemption".  They said "If the owner did not get an exemption from the county, the property is considered not occupied".  

So some things have changed at Listsource and they are not serving their customers well.
