I think mrusk has the right idea
repetition.
Interesting thing is I buy a listing of addresses of new homes purchased. I get a new list every month. Some months are only 20, some 60. Company is called NewPros.
My reasoning here was to target new people coming into town, or OK the few that relocate in town. I didn't see any worth in mailing to 20 year residents..........when they see my trucks all over town all year, every year...........and the adds we run.
NewPros in the beginning told me to follow up with the contacts no less than 1 more mailing.
Does it work?
I have no idea..............been buying the lists for 2 years and done nothing with them..........part of the problem with being a 1 man circus performer
For the first time..........I have 37 letters going out in tomorrows mail.........so we'll see.
All in all.........repitition has to work..........it works for me when I am in need of contractor work at the house
