If it is ebay, then sign into your account to see if there is any message.
If not ebay, DELETE
I believe it's eBay but not sure... When I sign in there's no message. I'm sure someone else has gotten this message before. Someone else I talk to on this site also got this message but don't know what it means.
UNKNOWN/EBAY LINK BELOW!!! eBay@reply1.ebay.com is where the message came from. Not sure if this is eBay but I've gotten it on a few accounts for different amounts.
