USA Today says spelling and bad grammar is a telltale sign of phishy communication. Large companies and organizations generally don't allow a mass email to go out with a number of errors.

If you think you've been targeted by a scammer, there are a few things you can do. The FTC recommends forwarding any suspicious emails to spam@uce.gov and to the company, bank or organization that the communication appeared to come from. If you spot a suspicious social media message appearing to come from your account, you should delete it immediately and change your passwords. You can also mark suspicious messages from friends as "spam."

Once you have secured your information online, then you can get back to surfing the Web and posting on social media more safely.
