Create a personal plan for single users with an entire domain of aliases.
I have an entire domain with individual aliases that isolate each account/sender. Before the service went to a revenue generating subscription model, I was able to receive domain-wide alerts. Please create an affordable plan for individual users that still require domain capabilities.
You can still enrol domains and receive alerts without a paid subscription. If your domain is very large, a subscription is required to then perform the search. If it’s very large and only used for personal reasons, drop us a ticket with the name of the domain and the number of addresses HIBP is reporting against it: support.haveibeenpwned.com
