Sometimes some spam emails irritate you a lot. Even if you have unsubscribed from them, they are still around you, keep coming into your inbox, which sounds very irritating. They will not go away until you take the next step.
I am going to discuss how to block an email address on
iCloud. We can not do this using iOS Mail app or iCloud email id in Outlook. Please go to https://www.icloud.com/#mail
Let's set up a server-side rule, which automatically moves all unwanted emails to Trash. The offender can send, but cannot irritate you anymore because the process is so quick that
you do not realize when and how those junk emails enter the inbox, and move away to Trash.
