blocking pseudo email names
I (we all) receive multiple spam/scam emails per day. Every site I've been to trying to determine how to block these emails is useless. The best way to describe the problem is with an example. So, I get multiple emails from ABC Co. (an example), which I want to stop from arriving in my inbox. Every site I've seen to date shows how to block emails by pressing on the sender's email name and them pressing the "Block this contact" option. This is useless because it doesn't block ABC Co. It on;y blocks the real address. I'll receive multiple emails from ABC Co. every day and every single one of them is in reality from a different email address even though every single one of them says it's from ABC Co. ABC Co. is a pseudo email address. The real address may be something like qiterv7ervcdsodbsifdg@gmail.com one time and will be something different, like 7yenvnwqyqfg@gmail.com the next time, and so on. But the pseudo address remains the same. I want to block any incoming mail that has "ABC Co." in the from field. Otherwise I'm forced to be blocking thousasnds of emails each with a different real address.
By the way, we should also be able to block emails based on the Subject field. I can do both with my mail client but not on my iPad or iPhone.
There must be a way to do this. If not, for shame.
