Inbox is full of junk mail and spammers,

My inbox is full of junk mail and spammers about 20 to 30 a day. It does not go in junk mail, but my inbox
I black mail them, but they continue to com back often on the same day.
What can be done to fix this problem,

Do you mean “blacklist them” using the eMC “Move to junk option”? Using what sub-option, email or domain, or just “Move to junk”?

Does your mail provider have a spam option that you can turn on? Who is your mail provider?
