Exact Data helps small and medium sized businesses acquire customers cost effectively, by selling highly targeted consumer and business email, postal and phone audiences. Exact Data is part of Data Axle, a large marketing data broker. Opt-out and deletion requests are handled by email to privacyteam@data-axle.com (or via the 'click here' / 'Do Not Sell My Data' links in the policy); include your first and last name, current address, prior addresses from the last five years, and which right you want to exercise. Data Axle says database opt-outs typically take 30-60 days to propagate, identity verification (possibly government ID) may be required, and opting out of their database does not remove you from their clients' or partners' databases.
