The pre-consent disclosures you describe are part of the "handshake" process outlined in ESIGN's Section 7001(c), titled "consumer disclosures." https://www.bankersonline.com/regulations/esign-7001
You engage in the ESIGN "handshake" for a single purpose--so that your outgoing electronic documents become "written" or "in writing" (the legal equivalent to paper.) Not all documents must be delivered "in writing." To make that determination, you have to look at the federal law, regulation, or other rule that requires delivery of the document in question.
Typically (but not always), federal disclosures required in transactions with consumers must be delivered "in writing." See, for example, Section 1005.4(a)(1) of Regulation E. Since federal consumer protection laws only apply to consumers (with minor exceptions), none of these disclosures ("written" or otherwise) must be delivered to entities that are not "consumers."
Even if there's a legal requirement to deliver "written" documents to businesses, you don't need to follow ESIGN's "informed demonstrable consent" rules (the "handshake") to make the delivery electronically. A simple service agreement will generally suffice for e-communications with any non-consumer entity.
