C# Send both HTML and Text email - most elegant?

Question

Is is best practice to send both HTML and Text email?

If I only send HTML what are the dangers?

I\'m thinking something like this below from

Several email clients will use the last AlternateView that was added to the AlternateViews.

So if you prefer to have your mail displayed as HTML, be sure to add that last.

I have notice this for IOS mail and OSX mail, while Android Email seems to prefer HTML if it is available. I am not sure for which versions this holds, and the behaviour is often user-configurable, but in my experience these were the defaults.
