Add Multiple To Recipients at Once

Demonstrates the Chilkat Email.AddMultipleTo method, which parses a comma-separated list of mailbox addresses and appends them all to the direct-recipient (To) list. Each entry may include a display name (e.g. Joe <joe@example.com>). This example adds three To recipients in a single call.

Background: The To header holds a message's primary recipients, and email allows any number of them as a comma-separated list. AddMultipleTo parses that standard syntax — accepting both bare addresses and named forms — so when your recipients arrive as one string (from a form field, database column, or config value) you can populate the whole To list in one step instead of calling AddTo per recipient.
