Consider providing the notice electronically:Consumer Compliance Outlook, Fourth Quarter 2013Overview of E-Banking Compliance Considerations
Consumer adverse action notices provided electronically are subject to the E-Sign Act’s consent requirements.[12 The consent requirements only apply to disclosures that must be provided in writing.

Operating under state UETAs, you simply reach an agreement with the customer and then proceed with the e-delivery.
