Notwithstanding the provisions of article one, chapter thirty-nine-a of this code, in a consumer transaction, an electronic record is not sent to or received by a party if the sender has actual knowledge that such party did not actually receive the electronic record. In that case, the sender's sole obligation shall be to take reasonable steps to attempt redelivery using information in the sender's files. This redelivery requirement is satisfied if the sender sends the electronic record to a different electronic mail address or to a postal address the sender has on file.
