postcard marketing to absentee owners

[Dan Miller]

I've sent out two postcard mailings now over 2 months to the same list of absentee homeowners in a particular are in the DC region, but gotten only 1 call (mailed 700 people each time). My list was generated from the tax records (via MLS) which can potentially be outdated though. (but it's free). I used the same postcard twice now.

So here's my question: how do I determine why my mailings aren't getting any response? My mail qtys are too small to really do testing of different marketing pieces, so I don't know if it's the mail piece, the list, etc.

I was planning to mail this same list a 3rd time in a few weeks. Would you suggest I try again with a letter to the same list (law of repitition) or should I make an assumption that my list is bad and go out and buy a new list of absentee homeowners?

Thanks!
