As long as it doesn't have any links to click or try to force you to login to something, it just sounds like information to me.
If my bank sent me something about Credit Card fraud I would be very skeptical if it had a big "CLICK HERE TO LOGIN" type of thing.
But if it was just info, and maybe ended with "Contact your local branch to learn more", but no links, no phone numbers, etc. I would be less skeptical.
