The only difference is delivery reports reported whether the email has reached the target recipient's mailbox or not while read receipts report whether the message has been read or not by the recipient. Read receipts are just like delivery reports with which we are all so familiar. The option was introduced by Microsoft in Outlook in order to help users track whether their email has been received and read successfully by the correct recipient or not.

Read receipts are a great way of tracking the status of your email.
