Thank you. Not sure I understand. So I block me.com or iCloud.com (whichever one I don’t use)? I tried setting rules in iCloud but that sent automatic responses to spammers and then doubled what I was getting.
No. The idea is not to block the entire "me.com" or "iCloud.com" domain.
The "Hide My E-mail" feature lets you fill in an e-mail field on a Web page with a one-off address that Apple generates. It's an address with some nonsense-sounding name associated with a server that Apple controls, which might be iCloud.com, but doesn't have to be.
When the Web site sends e-mail to this address, Apple forwards it to your real e-mail address without revealing your real e-mail address to the operators of that Web site. So you get the e-mail, but they don't know your real address. If they start abusing the privilege, or they somehow "leak" that address to spammers, you can go into Settings and tell Apple to "Deactivate Email Address".
Now when that Web site operator (or the spammers) send e-mail to that one-off address, it gets dropped on the floor. You never told them your real address, and you just "burned" the disposable one. Cutting them off – until they learn your real address some other way – without cutting off other people you exchange e-mail with.
Or, as the Ventura "Hide My Email" dialog says,
"Keep your personal email address private by creating a unique, random address that forwards to your personal inbox and can be deleted at any time."
