Massachusetts offers a very interactive website. In addition to the standard FAQ section on Unclaimed Funds and Additional Information for Holders, their site instructs owners how to file a claim and follow its’ progress online. Auction alerts are also available. You can even schedule an outreach event for your organization through this site. The state actively seeks to educate the public about its holdings through a variety of outreach programs e.g. visiting an assisted living facility, fairs.
