We aggregate 10's of millions of records from compilers, which we then clean, normalize, and verify for custom data feeds that are delivered to third parties for use in their products and services. Salutary Data is a B2B contact-data aggregator that sells professional/business contact records. You can submit a delete/correct/know request via their website form, by calling 1-866-451-4868 toll-free, or by emailing [email protected]; there is also a separate 'Do Not Sell My Personal Information' link on their site for opting out of sale/sharing. They will verify your identity first, confirm receipt within 10 business days, and respond within 45 calendar days (they claim a median of about 5 days). Because they continuously re-license data from third-party sources, your record may reappear and is worth re-checking periodically.
