My only question is what effect does encapsulating the body in html have for the email message. Are there situations where the html body will not get interpreted correctly?

This operates as standard HTML. Plaintext will correctly show up inside of the HTML tags.

From the testing I have done with this, the body as-is does not support native python string formatting (I specifically tried using \n -- it showed up literally), so I do not see concerns with the interpretation.

Can you confirm this?

Update on this:

I made this change in our local environment today. It was successful. I am now able to use HTML in the email bodies.
