Evaluate who you are trying to reach.
To maximum every dollar of your marketing budget, allocate your resources toward a smaller more targeted audience.
First, this will allow you to spend less money on producing mailing pieces, as well as less money on postage.
Second, your marketing message can be more focused and more specific to your smaller targeted audience.
Third, you can spend more time with following-up on your leads, and you will have more time to provide excellent client services to your existing clients; which can lead to more personal referrals.
With the right concise targeting, your message has the potential of reaching people that will respond. And, this may bring you more buyers and sellers.
