I am looking to send out between 2,500 and 5,000 post cards in the next month. I know with Christmas right around the corner, some people may not be interested in work right now. Should I wait until the new year before doing a mailout like this to try and increase the potential of new clients. Also, what would everyone recommend as being a good advertisement for this time of year (application for winter weeds, leaf clean-ups, discount off landscape projects, etc.). When does everyone send out their first round of postcards that does it?
