Request a Return Receipt for an Email
See more Email Object Examples
Demonstrates the Chilkat Email.ReturnReceipt property. Set it to true to request a return-receipt when the message is received; this causes a Disposition-Notification-To header to be added when the email is sent. The default is false. This example enables the request.
Background: A return receipt (technically a Message Disposition Notification, MDN) asks the recipient's mail client to send back a small confirmation when the message is opened. It is only a request: the receiving client or server is free to ignore it, and many prompt the user before sending anything. Because of this, a return receipt is not reliable proof that a human actually read the message — treat it as a courtesy signal, not a guarantee.
