Eek, No!   Not only is that not well supported amongst mail clients.
It's not even enabled most of the time on supported clients (including
Outlook).  Also, it's a very ugly process.  Essentially the client
just sends you an email that indicates it was read.

Please do not use read receipts.  Even the slightly clumsy URL
tracking is leaps and bounds better than read receipts.
