There is no self-service opt-out form — you must email privacy@realsourcedata.com to be removed from RealSource's marketing databases, or to request access/deletion/do-not-sell under CCPA. The company's own disclosure reports an average response time of about 22 days. Removing your name and address here won't stop other companies from mailing you, and since RealSource continually compiles data from many outside sources, it's worth re-checking periodically.
