Delivery Receipts - A delivery receipt confirms delivery of your email to the recipient's mailbox. However, unlike the read receipt, the delivery receipt can't confirm that the recipient has seen it or opened it.

Read Receipt - A read receipt confirms if your email was opened by the recipient. Important: Some users allow the recipient to choose not to send a read receipt. Do not rely on this feature.

These options can be easily accessed/set via the message composition window.

1. While composing a message, click the extended menu .

   

2. Next, click show message options.

   

3. Place a check mark next to the request a read receipt option and click OK.

You can request a delivery receipt to let you know when a message that you've sent has reached the recipients. A read receipt will tell you when a message that you sent has been marked as read. Some email programs allow recipients to choose if they will respond to read receipts.
