@haveibeenpwned I was wondering why mine didn't appear on the list but I guess it makes sense if the email address was the input for the breach (catch all email domain here so my Twitter specific email won't be on previous breaches)
@bootlesshacker @haveibeenpwned You can get notifications and past breaches for a while domain:
haveibeenpwned.com/DomainSearch

Not as nice of a UI but completely workable
Have I Been Pwned: Domain search

Have I Been Pwned allows you to search across multiple data breaches to see if your email address or phone number has been compromised.
