Depending on the type of account (deposit, loan, etc.) and the timing of the specific disclosures you must give, you may still want to consider sending courtesy copies of disclosures by email. So long as the official copies are properly timed and "written" (including ESIGN-enabled documents), additional e-copies could improve your marketing effort by helping customers compare options and make decisions before showing up for face-to-face formal applications & account openings.
