You'll keep getting these for a bit, most likely, but keep just deleteing them. They are just checking out your email addy, most likely.
If you respond in any way (like clicking a link that says "Click here if you do NOT want these emails", then you'll be marked as a live address and the spam will commence in earnest!
So just delete them. If possible, don't even read them, or better still, bounce that particular address if your email prog will allow that.
