(a) An association shall deliver any notice required to be given by the association under this title to any mailing or electronic mail address a unit owner designates. Otherwise, the association may deliver notices by:
(1) hand delivery to each unit owner;
(2) hand delivery, U.S. mail postage paid, or commercially reasonable delivery service to the mailing address of each unit;
(3) electronic means, if the unit owner has given the association an electronic address; or
(4) any other method reasonably calculated to provide notice to the unit owner.
(b) The ineffectiveness of a good faith effort to deliver notice by an authorized means does not invalidate action taken at or without a meeting.
