@haveibeenpwned You sent me a mail telling me that an address in my single-user domain was involved in this breach. Thing is, I'm not a HIBP subscriber.
The link in the email took me to a page which wanted me to subscribe to a service which costs hundreds of dollars per year to see the details because apparently you think I am an ISP because your data is extremely dirty as it contains loads of invalid addresses generated by spammers using dictionary attacks.
So I forwarded the email to abuse@sendgrid.com pointing out it was spam. Because if you're bulk-sending mail to non-customers trying to get them to pay money, that's spam.

I think you're mistaken, while HIBP has a paid service it will provide data on affected domains for free. Source: I monitor my domain for free at HIBP.
