The problem with this is, of course, you assume that a user is going to be using a client that supports this type of feature such as Outlook. (Read Receipt)

Most Web Mail clients do not have this ability.

Not to mention that you then need to program something to check an email account, read the mail, etc. etc.

It would probably be far easier to use email image beacons. You create a record in a database with a unique ID (GUID, auto increment number, etc). Then you put an image tag in HTML in the body of the email. The URL of the image points to a special handler page on your site and includes the unique ID in it. The handler updates the DB record with the "message read" status and returns an actual image that the user then see in their email. This is how all bulk mail services work. Next time you get a marketing message from a site you've purchased something from, take a look at the image tags in the message source. They are full of long identifier codes.

Of course, this working is dependent on the user allowing images in mail (something that is now commonly disabled until the user allows it for the message). However, this isn't really any different than a user needed to approve sending a return receipt for the message itself. You are simply not going to get a 100% return.

If you are looking for a more reliable message delivery tracking approach, you could save the messages to a database, and send simple email telling the user to "go here" to see the message. Then your message delivery, and thus the tracking mechanism, is part of your web application and you will have far more control over it.
