I have an initial.surname email account with what used to be my ISP. I do get emails relating to one stupid cow in particular who obviously cannot be bothered to type her correct email address for the shops she uses.
I once got an email asking for a job reference for someone she knew. I replied to the employer with a "not me, guv"; I hope it brought that person a rejection.
Sometimes I get emails about credit purchases and arrangements. These I seriously try to correct as it could tarnish my own credit rating.
