Can't block daily Grammarly Spam in iCloud mail

Been getting non Stop SPAM from "

" the Spam claims that " You haven't used Grammarly in a While" Like an old friend just sayin hello! I have never used grammarly and never will. I can't stop these creeps from spamming my iCloud account daily.

I have set up rules of all type in iCloud mail, it does nothing at all, the spam continues. its apparent that Apple can't stop this junk or doesn't care too. When I get a daily SPAM from these creeps and try adding RULES to Forward the grammaly SPAM to spam@iclound.com it says that rule already exist. Apparently it doesn't work! That brings us to the most obvious and profound question of all for Apple; Why does Apple Mail SIMPLY have a BLOCK SENDER option instead of the worthless ambiguous and time consuming "RULES filters" as if we would like to finally tune the spam that is so freely allowed to proliferate as much as this Grammarly junk is.

The old Unsubscribe trick Grammarly uses only assures them as that got a live one , apparently too many trusting people are deceived by that insidious tactic.

So... Apple; here is what You need to do Now.Just add a BLOCK Sender to apple mail !!!! Seriously .
