Not receiving emails

I have a windows live email account I am expecting two emails from unknown senders but have not received them they are not in my junk and I cannot ask them to resend due to not knowing their contact details. I have checked my filter content and it is on standard so I am still receiving emails in my junk although not many at all! I really need these emails as they are job opportunities and not receiving both when the sender has told me they have sent them shows there is an issue!
