Who do you use for data providers?
Edited
We use several different data providers and decision off of all of them depending on different circumstances.
The exact providers are proprietary as is the decisioning logic but we can share that some of what we are using is data verified from MasterCard and checked against tax records.
Any lead we would pass to your CRM would be someone that converted and claimed one of the offers and is expecting to hear from you. We won't hand off de-anonymized visitor data into your CRM.
