Good intentions, great start.
For the particulars, you'll have to try out your marketplace. We're working tax delinquent and code violations in our market, so far response rates have been lame on mail.
Based on everything my partner and I have been learning from experienced guys, you'll need a multi-pronged approach. Some will come from Facebook, some will come from google adwords, some will come from your mail, and some will come from word of mouth.
We're trying to get that all built out right now. I would say this, however, your standard generic postcards, from our experience and from others in my marketplace, are at an all time low in terms of performance.
At the moment we're thinking about how we can stand out. Seems the 'tried and true' stuff isn't performing as well as we'd hoped using fairly conservative estimates.
Best of luck, sounds like you have an awesome start. Thanks for the read and keep doing the world some good.
Best,
JTM
