I just received the same email and was googling the number left by a "Jenny". It's definitely a scam. Delete!

This telephone number wal left in an e-mail stating;    "your new check is ready".  just give us a call. " we want to deliver to you right away". valid only for an hour".    jenny.

Can't find any reason for this e-mail,   probably  a scam.

This number was left in an email stating that I had a "check waiting for pickup".  Can't find any legitimate business with that number so it's obviously another scam.
