Email read receipt?in MAIL

[cpnotebook80]

Does the mail program in Mac have a tracking requesting a read receipt or when email is opened for email sent like in Outlook in windows?

If not, do you think this would be implemented in future mail update?
thanks

I found this site with some information and looks very complicated!
