OK, so clearly it's not real. Let's talk about the indicators...
- The From line - the email address doesn't match the name of the sender
- A Reply-To line that is yet another different address. In this case I'd expect addresses with treasury.gov or something similar
- Generic greeting - it doesn't use my name, or any name, or a company name
- Promise of a big payout - no, I didn't win!
- Generic info - once again, nothing that refers directly to me. Yes, I guess this could be a generic form email, but not for this kind of payout!
- Call to action - while the email contains no links or attachments, it first enticed me with a big payday and then wants me to take action. And what's the harm in replying?... it lets them know that I am real and that I am willing to take the next step. The next step could involve: sending my bank info, providing other personal info, or even arranging an in-person meeting.
- Context - perhaps most importantly, this email just doesn't make sense for me. I don't own a company and there is just no context for me receiving this.
Do you see any other indicators? Would you have responded?
