Since WHOIS is obsolete, you could try RDAP.  If that doesn't work, use the
email address that's part of the SOA record (which is what it's for,
really; see 3.3.13 of RFC 1035).  Still, automation of such notifications
runs the risk of generating a lot of unwanted email, so we would really
need to undertake such an effort carefully.
