Spam is killing me

Spam is consuming about 80% of my incoming email volume. I mark it as spam but it keeps returning.
I have looked at the white list and blacklisted and all are empty

I have never added any to either so that is not what has changed. It seems this started happening in the past month about the time of the Zoho upgrade.

I never had this amount of spam show up in my inbox . When i marked an e mail as spam, it started going straight to my spam folder but it no longer does.

What is up with that? If you cannot fix it, I am moving on to another service. I cannot put up with this amount of spam
