Failing at direct mail. What am I doing wrong?

[Christian Marin]

I've started doing direct mail for 2 months now sending 250 letters a week to a 1,000 names and all I've gotten is people wanting market value for their homes or people calling me names. Today I got 3 calls from the same seller so I thought he was really motivated. He ended up calling me a "maroon" which I don't even know what it means but it's pretty funny. Am I the only one going through this or this a common thing when you start direct mail?
