Has anyone ever dealt with a persistent spam operation like this?

First, the mail system is Spectrum cable and Outlook 2019, POP3

I get 5-10 of these a day. The sender nor the domain is ever exactly the same, so I can’t block the sender or a domain. I tried blocking just a partial, i.e “businesswoman.com” and that does not seem to work. Of course the email has the ubiquitous "click here to unsubscribe" but both McAfee and Netgear Armor tell me if I insist on following that link they will disown me, so I haven't, lol.

WHOIS says the domain, as an example “@mike6russell7businesswoman.com” is available. Are they translating the real domain by random generation? Is there any way to determine the real domain? Any ideas how to block this stuff. I have not yet dropped back to Spectrum to see if there is anything I can do there, but will try that today. TIA.


Here are examples, the first few with the descriptor stripped away from the sender line:
