I am using iCloud email use that for shopping and tired of getting email from certain senders. I have to delete unwanted emails or to move them into the Spam folder. How can I block unwanted emails so the sender can’t send them to me?
There is no way to block unwanted email in iCloud. All you can mark it as spam or create a rule to discard emails from a certain address. You can also create a email alias in iCloud and use that for that where you might get spam.
