In order to be valid, Section 7001(c)(1) requires that the consumer must provide you affirmative consent. The act of consenting must be done electronically, in a manner that reasonably demonstrates that the consumer can access information in the electronic form that will be used to provide the information that is the subject of the consent. In simple terms, you must set up a test drive and require the customer to prove (in advance) that s/he has the hardware, software, and savvy to be able to receive, open, and read a test document.
