they're not real.
What is Phishing?
Phishing is when someone sends you a fake message, pretending to be someone they're not. These messages generally appear to be from a bank or credit card company, asking you to click on links and give them your personal information. Real banks and credit card companies know of these scams and don't ever ask for this information through email or text.
Don't ever respond to an email that might not be legitimate.
