How to delete an annoying email?

Send them $1000.00 by wire transfer to claim your portion of the Naginagi foreign lottery :)

If you clicked on it you probably opened a virus or trojan horse which is you can't  delete it 

I got the same email. I had Tammy in customer service delete it.  I never opened it as I could pretty much see the content.  Btw, I scanned it both with the Windows 10 built in anti virus software and Malwarebytes and it came up empty. 

I received two copies of the same PM on October 23rd, which was the day he, she, or it registered here.

You can archive the message and/or see its contents by first clicking on the date shown for it in the list of your PMs.  The next screen will provide a link allowing you to transfer the PM into an archive folder.  That screen will also state that "this conversation contains spam," and will provide a link allowing you to see the contents of the message if you wish to do so.

What is said in the message is basically "I'm Natasha, please kindly respond back to me through my email address," the email address being the one referred to in the OP which is also what is shown in the subject line of the message.

BTW, Googling that email address shows that he, she, or it has sent identical spam to many other forums.
