I had four of those emails yesterday, all for different amounts.
All these scum bags need is for one or two people to be sucked in and they will clean you out.
You will read in bank websites that they will NEVER send you such emails, either forward them to the bank using their phishing email address that banks list in their websites, or just delete them.
I use Santander and they will send me an email telling me there is a secure message for me in my online account. That's the only way we communicate online.
