I've seen emails similar to this come through my Mailbox far too often. Thankfully, they end up coming from banks where I am not an account holder. Of course, this won't always ring true. If you end up getting an email similar to the one above whatever you do, don't click on the link.
It will send you to a bogus website designed to look like it came from your bank. But if you roll over the link, chances are it's sending you somewhere completely random (can usually see where it's taking you from the bottom of your web browser). This is one of many forms of phishing that we see online everyday.
If you look at any bank's policies, they will clearly state something akin to "Reminder: (Bank Name) will never ask for your PIN or password over the telephone, by text message or by email."
The truth is, they won't. People can sometimes be too trusting and begin clicking on links thinking that they are official, when they actually turn out to be the opposite.
The bottom line is that most emails you get from your bank will probably just be information regarding upcoming promotions and services your bank offers. They will never send you official statements saying that you need to confirm your information.
If you are still unsure, call your bank to let them know about the email you received and they will be able to assist you. However, it's much easier to just go on the belief that it is a bogus email. Banks are not that reckless with your information.
