Technologies for attributing purchases to a targeted marketing campaign include associating a captured payment card number and a captured cardholder identifier with a globally unique identifier. Additional payment card numbers related to the captured payment card number are associated with the globally unique identifier. A cardholder-specific marketing message associated with a targeted marketing campaign is transmitted to the captured cardholder identifier based on the globally unique identifier. The targeted marketing campaign is for an advertised product, which corresponds to a product identifier. A purchase transaction is attributed to the targeted marketing campaign in response to determining that a payment card number associated with the purchase transaction matches any of the payment card numbers associated with the globally unique identifier and determining that a product identifier corresponding to a purchased product of the purchase transaction is associated with the targeted marketing campaign. Other embodiments are described and claimed.
