For a young business same-street proximity mailings are great idea. You can reach a targeted small neighborhood to showcase a project that you are currently working on. But this approach takes some time to implement. Your marketing has to be very custom and it has to have a very personalized feel to it. The key is to make sure it doesn’t feel like bulk mail. If your marketing is done well, it’s worth the time you spent putting everything together. The return on investment, or ROI, is very high.
