You're welcome. 🙂
With our previous business email address, you can't just close them and make a new one. Too many people to contact and let them know what the new one is.
But some years back, I was getting a dozen or more per day of the dumb emails claiming "You don't know me, but I have put a Trojan virus on your computer. You won't be able to find it. I have videos of you doing naughty things. Send (random amount) of money to this BitCoin account (account number given in the email), or I'll release the videos."
Well, I already knew it was a scam, and it would be a true miracle to have such a video since we have no cameras of any kind on our computers. And you couldn't block the sender because their main trick is to spoof your own email address as the sender. Obviously, if you block that, you block everything coming to you. Legitimate or not.
Instead (and you can do that in a Gmail filter, too), I'd put in a phrase that was common in the body copy. Add that as a filter to immediately delete the email without ever putting it in the Inbox.
Every once in a while, they'd change the text just enough that my phrase wasn't an exact match, and they'd get through again. But then you just another common phrase to your filters.
Over at least 4 years, at roughly a dozen per day (and that's a low estimate), there were roughly 18,000 of those stupid scam emails I never saw.
It will be the same for you. It doesn't stop the emails from being sent, but unless they change something that no longer matches your filter, you'll never see them.
