You can easily add mailing to your job using Greenerprinter's simple ordering process. Save yourself the time and hassle of addressing, applying stamps, dropping off at the post office and get a discount from USPS! You can either provide your own list or purchase a list during the ordering process. Our online list ordering process gives you many geographic options; distance from a starting point, zip codes or states. Filtering is available for over three dozen demographic criteria from age to income to travel. Note: If you select a criteria, you must scroll to the top of the list to view the available options for that criteria.
