I have access to lists for mailing Their Industry lists for almost everything available. Both down to the region and zip codes to all over the country. Each list I have has been run through what I call NC48, it takes the addresses and runs it against a big USPS database and any (address) moves made within 48 months that are reported to USPS it then takes the new address and updates the list. I'm curious is there a way I can create or start a small income? Any help would be appreciate or suggestions itself. Thank You.
