It is obviously a scam, because
- I don’t know the senders
- It’s to an email address I no longer use and that gets spammed frequently
- It’s from a PayPal affiliate in the country of the email domain (I no longer live there)
What is the game here? Is it to confirm my email address is real? Will they claim the money back? Or would I become a money laundering mule when they ask me to send the money back to a different account? I just can’t come up with anything that sounds remotely profitable to me.
