Mostly that stuff doesn't serve the purpose you would like because
'other entities' such as the recipient or the server are in control of
part of the process, not you.

When you send a mail 'requesting' return receipt, it puts a header for
Disposition-Notification-To and if you will examine the mail you
received which you sent yourself with the receipt request, you should
find that header.
How Tb handles its behavior toward you the recipient when it receives an
email with that header depends on the settings in the mail account in
the return receipts section. The default setting is to use the global
preferences which can be configured to never send return receipts or to
ask or to always send return receipts for particular kinds of addressing.
In the past I have configured to never send return receipts; now I am
configured to ask whether to send return receipts. If you are
configured for never, you aren't going to be asked even though the
header appears in the received mail. Likewise if an other recipient
receives such a mail you might or might not get a return receipt
depending on how the recipient is configured - what the recipient's mail
agent 'wants to do' with that header and/or what the recipient hirself
wants to do about it.
In my opinion, the return receipt business (or its facsimile) should be
a courtesy which is worked out between the sender and the recipient and
not configured into their mail agents. For example, the
sender/recipient could have an agreement with each other that when a
mail is received that the recipient hits reply and sends an empty or
nearly empty mail message with the same subject (and maybe top line)
indicating the recipient is in receipt of the message.
Regards the delivery status notification; that is a server response when
it receives such a message to put into the recipient's mailbox, which
isn't exactly the same as a recipient opening the mail. The moz kb
article says that servers support that header, but it is my opinion
(based on not much) that servers don't do that extra little bit of work,
that the server software is configure to ignore it even though the
server software could be configured to respond to it. (And for good
reason, see spam below.)
So, since (I believe) servers and recipients don't 'routinely' behave in
the way you might like, I believe that you and the recipient should have
some kind of agreement between you about your being notified when the
recipient gets your mail.
Incidentally, it is a big spam no-no for a recipient to be configured to
always send return receipts, because that functions to the spam system
as an address confirmation and spam-reader status for any such spams
that are opened as would be the delivery status notification by the
server confirming the spammed email address.
