Add an HTML Alternative Body to an Email
See more Email Object Examples
Demonstrates the Chilkat Email.AddHtmlAlternativeBody method, which adds an HTML alternative body. Combined with a plain-text body, it produces a multipart/alternative email that offers both representations of the same content. This example sets a plain-text body, adds an HTML alternative, and prints the resulting alternative count.
Background: A well-formed HTML email usually ships two versions of the body: a rich HTML version and a plain-text fallback, wrapped in a
multipart/alternative container. The receiving client displays whichever it prefers — modern clients show the HTML, while text-only clients (or spam filters and accessibility tools) use the plain text. Providing both improves deliverability and ensures every recipient can read the message.Chilkat VB.NET Downloads
