Some plans’ administrators might use a disclosure regime conceptually like your description, but with different means, by following the Labor department’s rule for a participant’s, beneficiary’s, alternate payee’s, or other covered individual’s implied assent (by not generally opting-out) to notice-and-access electronic disclosures.
Among many conditions, the regime requires that the individual furnished, or was assigned, an electronic address (which remains operable).
