Sounds like a scam. Firstly you aren't a customer, second there is a link IN the email and a bank would tell you to go to the site via your normal route.
Haven't had that one but in the past I have had a Halifax one and Barclays (neither of whom I bank with). I reported both using Google to search for the emails of each company, had nothing back from the Halifax and Barclays actually emailed me like I was the one doing it! I 'politely' but firmly emailed them back and got an apology.
