Apple iCloud has a great feature called "Hide My Email", where you can create an alias email address (which it generates similar to a password generator) for any account or source you want to give it to. It associates each auto-generated email address to the user's main iCloud email address. This allows the user to disable that alias email address if it gets on the Dark Web or it starts receiving spam. I have dozens upon dozens of these alia email addresses. I'd like your system to check the dark web for each of the alias email addresses, whcih would require it to synchronize with the user's iCloud account.
