Most such e-mail traffic is just spam, not sent by the banks, but sent by people hoping to trick the recipitent into reading the e-mail, following the link and logging into a false web page set up to act like the bank web site.
Once they have your logon details they will go to the real bank page and transfer out your money.
I don't click on most email links because you never know if it's the scammer or the company.
Of course. But it's a real bank statement and it's a real mobile bill that makes its way into my inbox each month. Used to, I mean before I created a filter to delete it as soon as it arrives.
