The best thing is just for the receiver to avoid opening such mail as long as it obviously appears as a scam looking at the appearance.
They always find ways to make their spamming became more attractive that's why the best thing we could able to do is totally ignore those emails we get. Also once we receive a lot of same like attempts and any unwanted emails came out of nowhere then that means that email we have has already been compromised and been in the target list of those scammers. So much better if we should abandon it already since there's nothing good if we continue to use that and provably we could receive more scam emails like that or worse they can totally penetrate on that emails we have.
Better use fresh emails and make sure that this is away from any potential tracking of those scammers then don't use it to sign up on any random sites to avoid same situation to happen again. Being curious on what we see on our emails is so bad and we should ignore those potential phising and hacking attempts so that we make sure that those criminals cannot get something from us.
