This article will show you how to set up a delivery receipt for your 123-reg Mailbox using webmail.
A delivery receipt is an email you will receive to confirm that your email has been sent to, and arrived in, the right mailbox. A delivery receipt differs from a read receipt, as you are only notified when your mail is delivered, and now when the recipient has read it.
Open a new email by clicking on the New Email button.
Click on the View button and then select Options from the drop down menu.
Tick the Delivery receipt box to turn on the receipts.
You will now receive a delivery receipt once the email has been sent.
