I can't help with industry practices, but e-delivery (with proper ESIGN consent) is certainly an option for delivering the long-form notice annually. Whatever you decide, be sure all customer contact employees know that the familiar old notice is going away, and that change could increase the number of one-on-one questions from customers. I might also be a good idea to remind them of what it takes to start the error resolution countdown. More conversations = more opportunities to get it wrong.
