SDM has been providing letterbox distribution services in Singleton since February 2012. We work exclusively in Singleton and are committed to providing a focused, professional service that effectively serves both our clients and their customers, the residents of our community. Our Policy is we respect the wishes of residents and do not deliver to mailboxes with No 'Junk Mail'/No Advertising Materials or similar signs on them. We try to keep records of residents who do not have signs but have requested non-delivery, but unfortunately this does not always work as walkers change areas and cannot remember many different verbal requests. Bundles are delivered in mail �tubes' wherever provided so as not to interfere with regular post. We do not allow littering or throwing mail out of car windows, we do not deliver to mailboxes that are full or overflowing and all excess stock is recycled.
