Add a Plain-Text Alternative Body to an Email

Demonstrates the Chilkat Email.AddPlainTextAlternativeBody method, which adds a plain-text alternative body. Combined with an HTML body, it produces a multipart/alternative email that carries both representations. This example sets an HTML body, adds a plain-text alternative, and prints the alternative count.

Background: This is the companion to AddHtmlAlternativeBody. A polished email provides both an HTML body (for rich display) and a plain-text fallback, and the receiving client picks whichever it prefers. Including a real plain-text alternative — rather than letting the HTML stand alone — improves accessibility, helps with spam scoring, and guarantees the message is readable in text-only environments.
