DatabaseUSA.com offers the best databases of U.S. Email Lists, Mailing Lists, Database Services, Data Enhancements & Data Licensing. DatabaseUSA has no direct opt-out link in the policy itself — you must go to their homepage and use the "Your Privacy Choices" webform at the bottom of the page. They state processing takes 30 to 60 days, and the opt-out only covers DatabaseUSA's own database, not clients or partners who already received your data. State-specific privacy supplements (e.g., California) are linked at the top of the policy, and a phone number (877-831-0101) is given for questions.
