Email - real or a scam?

I continually get questions about how to tell if an email is "for real" or a "scam?"

Sometimes it is very obvious when reading an email that it is a scam - misspelled words, poorly designed, etc.  But other scam emails may be very professional and look like the "real thing."

So, how can you tell?  I recently received a very authentic-looking email from Apple.  It was a bill for something I had not purchased.  My immediate reaction was, "Oh, no, my account has been compromised."  But, before contacting Apple I decided to check out a few more things.

I made this 4-minute video to show you what I did (and what I recommend you do when in doubt): https://screencast-o-matic.com/watch/cFj2Xgql1p
