yellow letter campaign

[Marc Oister]

I had a few questions about yellow letter campaigns that I have been having trouble finding answers to on here about yellow letter campaigns. 

  I have sent out my first full direct marketing campaign through yellowletters.com.  It has been a run of 1200 yellow letters spaced out 400 per week with the last 400 going out two days ago.  So far from the first 800 letters I havent had one any phone calls as of yet.  I  am targeting absentee owners with equity of 60%+.  It has me wondering if this is normal to have to wait for a few weeks for calls or if I should consider the first two drops a bust and hope better on the third.

  At this rate I feel that postcards will be a more value conscious choice considering my rates so far.  I am planning on contacting all of the 1200 again via postcard in a month, while hitting another list with yellowletters at the same time.

  Anyway how long does it usually take to hear back from a mailing campaign.  I have been targeting the suburbs of philadelphia if there is anyone also in the area. Mainly montgomery county.
