We started this about two years ago. We realized that post cards, magnets, seeds for spring really do not work. It is old school marketing and those using it are wasting dollars better spent elsewhere. We started a neighborhood directory.
Here is what we did: we mailed out to the 125 homes in our farm area (those directly around our home) a letter asking for info like name, address, phone #'s, e-mail addresses, and age and sex of children. We did the mailer 3 times and let them know we would not use it for marketing (we let them know so they would not think it was a gathering of info for a barrage of e-mails). We did it low key...no advertising...just a picture of us on the back cover and a brought to you by Team DiMuria with our contact info. We added things like pool schedules, our favorite local restaurants, and emergency numbers.
It has been very successful and always gives us a reason to contact new neighbors so they can get their info in the directory. It also allows us to quickly announce things like a neighborhood block party that we sponsor! We have received leads and referrals from it...and we are known as the neighborhood experts in large part because we are the picture they see every time they need a neighbors phone...or order pizza!
