Read and delivery receipts: How they work
Before you send a message, click the Options tab. Then, click Request a Delivery Receipt or Request a Read Receipt. When you send the message, it's routed to the recipient's email server, which delivers it to his inbox. And the server sends the delivery receipt you requested. Note that the server, not the recipient, is shown as the sender of the delivery receipt.
When the recipient double-clicks the email to open it, he can choose to send you a read receipt or choose not to.
