Door to door newsletters--do they work?

Thank you to everyone who responded with terrific feedback!  It was great to hear that it works.

Next question--do newsletters left on doorsteps work?  Better or worse than flyers?

I have a realtor client who is trying to set up four legs of marketing, and I would love to hear what is working out there.  Like each of you, I'd like for him to been seen as an expert and I need creative ways to get him in front of people in our community.

Thanks, everyone!
