The email was quite simple:
The subject line displayed only the recipient's first name.
The body of the message was this, and this alone:
I saw you in this video! https://bit.ly/<random 7-character string>.

Both links above point to the same article, but the second link is a "short URL" that I created on bitly.com. These are also known as "tiny URLs," and they are easily decoded.
If you get an unexpected or unusual text message or email enticing you to click a tiny URL, be sure to decode it at a site like checkshorturl.com and verify the destination domain is trustworthy before clicking it.
