I have been getting tons of daily spam from seemingly every US Retailer (yes, none of them are from the retailer) .

The subject lines are often similar to this:

Ace is the place for your $1OO-Reward (See Details) 79012353

or this:

Home Depot Customer Your Opinions Matter up to $100 Reward #4056099

Often the 'prize' is 1OOO with the letter O and no a zero.

from senders like:

Christine Kausch <christine-kausch@sidetopz.xyz>

or

Kristine Tingstrom <tingstrom-kristine@rubstudio.click>

The body is often similar to this:

the maillog notes that they are spammy, but lets them through.

Is there some training I can do to get all of these blocked?  I literally get 100s a week.
