I’m very careful with privacy and security so I was surprised I got an obvious phishing email from “American Express”. I reported the email and moved on only to get another one today. I checked haveibeenpwned and it came back clear. I have never gotten a phishing email before the other day. As for the senders, they all came from generic IT sounding email addresses. They obviously weren’t American Express.
yahoo! mail offers throw away aliases you can delete if you get spam on one.
So does Tuta which I currently use. It’s funny one of my aliases was in a breach recently.
