Make a Copy of an Email

Demonstrates the Chilkat Email.MakeCopy method, which copies the entire state of this email into another Email object — message content, recipients, headers, body representations, attachments, and related items. This example copies an email and reads a couple of fields from the copy.

Background: A deep copy gives you an independent duplicate: changes to one object do not affect the other. This is handy for template-and-tweak workflows — build a base message once, copy it per recipient, then vary only the recipient or a few fields — without risk of one send's edits bleeding into the next.
