If your e-Sign demonstrable consent covered the receipt of other disclosures required by law in connection with the accounts, I think you could be covered. You could include the link in each email announcement of statement availability (or you could include the language of the notice in the email itself). Or, I suppose, you could include the link in each statement (probably more complicated than the other suggestions).
In cases in which you provide the link, I'd recommend it be clearly and prominently displayed. Something like "Click HERE for information on correcting errors involving electronic transfers."
