Vt. Stat. tit. 21 § 1357
Notices required under the provisions of this chapter, unless otherwise provided by the provisions of this chapter or by rules adopted by the Supreme Court, shall be deemed sufficient if given in writing and delivered to the person entitled to it by an agent of the Commissioner, or sent by ordinary or certified mail to the last address of the person appearing in the records of the Commissioner. The manner of service shall be certified by the agent of the Commissioner making the service. Regardless of the manner of service and unless otherwise provided, appeal periods shall commence to run from the date of the determination or decision rendered. If a person to whom a notice has been sent files with the Commissioner within 60 days after the date of the notice a sworn statement to the effect that the notice was not received, or if the Commissioner is satisfied that the addressee did not receive the notice, a new notice shall be sent to that person and the appeal period shall commence to run from the date on which the new notice is sent.
