Abstract: The present invention is directed to a system and method for masking email addresses. In an exemplary embodiment, a consumer responds to a marketing offer by supplying consumer information, including an actual email address, to a lead specialist. The consumer's actual email address is masked, with a unique email address substituted, when the consumer's information is passed-on to a lender. The lead specialist can then track and filter responses to the consumer to identify misuse of its lead information and to protect the consumer from unwanted emails and solicitations.
