I am using windows 10 with and running a gmail account. Every day I receive junk mail with no subject line which I cant block.

I then save it to my inbox and it say that the email has been blocked. I look at the drop down address and the option for blocking is not there. So I presume that it is blocked but they keep coming back every day. The address it showing is *** Email address is removed for privacy *** is this junk mail from google?? Do I have to close my Gmail account to stop the flow of junk mail from this address, *** Email address is removed for privacy ***

Please help.
