This can be done either by EDDM mailers or by an addressed list mailing. If using an addressed list we would simply sort the list and target only the areas nearest your zip code..
EDDM(Every Door direct Mail) pieces are well suited for saturation type mailings and are distributed door- to-door by the postman, he will simply put one in each mailbox along the routes selected. Usually done in a 1-5 mile radius of your location. Entire route must be covered when you do this type mailing. No stamp is used, an indicia is printed on your mail piece.
Typical businesses that use these are salons, restaurants, clinics, gyms but also service type businesses such as landscaping and roofing contractors. Postage rates for EDDM pieces are .18 each and sizes must be flat sizes only.
