We help global marketers keep their contact data clean, current and compliant. RampedUp is a registered data broker (CA, OR, TX, VT) with a dedicated 'Do Not Sell' web portal at basic.rampedup.io/app/donotsell where you can request access, limitation, or deletion of your business contact data. Requests must be submitted through the online form and confirmed via email; authorized agents must show proof of authorization. There is also a toll-free line (888) 278-3433 and legal@rampedup.io as alternatives. They confirm receipt in 10 days and respond within 45 days (extendable to 90). Because their data is continuously refreshed from public web sources, it's worth re-checking periodically.
