Re: Mail marketing VS Door hanger
It would completely depend on the time you do it.
If you do it say, 7:30ish (at least in my locale) you would catch people coming out for the paper, or putting our trashcans/recycling bins. Thus they would be in good spirits. You don't want to catch someone trying to get in their car to head to work, as they will be in a rush and not want to be stopped.
When I as younger, I used to put up the door flyers. You do see a lot of the people (I did it from 8am-11am, trying to catch them when they weren't home). But when someone leaves something on your door, do you look at it?
I find you have a greater chance of success with mailings then door knockers.
I would say, run a test in your area. Find a street, and things west of it you go door to door, and things east you mail. See what the conversion % is.
If you're not remembered, you never existed.
