Every domain registered has publicly listed contacts for administration, billing, and technical. In the web world this is known as "whois" information, as in "who is in charge of this domain?"
Internet standards require that domains have this information, and they require that HotDoodle send occasional emails reminding that owners have the right to correct the listing. The language in these messages is confusing, but the word choice is mandated by internet standards.

ICANN, the organization responsible for the stability of the Internet,
requires that each domain name registrant be given the opportunity to
correct any inaccurate contact data.
