The spam filters don’t really work on the email platforms I use. My guess is that the spammers use a whole range of origination emails. When one is blocked, they just resort to others.
There is a way to block those that change- I think though it involves es blocking domains or something.
My email has key words I can block, like “electrolysis” or “financial”, or “realtor” for examples, words you know that folks wont use in their emails to you...
but you have to be careful not to block words that are common in emails,from people that you want email from. Pick the unusual words in headers or subject headlines to block
Not a perfect solution, but it does cut way down on spam, and works when the email address of sender keeps,changing, but their wording doesnt
Hmmmm..
My email allows me to check (select) an email, then click mark as spam, and it disappears into the spam wormhole (wherever that is)..
