Many authors of spam emails use the DELETE option as a ploy and it only shows the spammer that you read their email. I don’t open any email I don’t recognize and send it to spam. The same with telephone calls.
Re calls; I received a call from a number that I didn’t recognize but it came up as a tire company in Athens, Alabama, close to where I used to live. They left a voice mail and when I listened to the VM it was typical boiler room bullshit.
Spammers are smart. You have to be smarter than them.
