I'm not sure what you are using to send SMTP email, but most
SMTP client software returns a code that should let you know
everything was received okay.
SMTP client software and SMTP servers are having a conversation
based on the SMTP protocol once they are connected. It usually
starts with a HELO to the SMTP server, which acknowledges with
a 250 code and text for things like Mail From, Recpt To and the message
being queued on the server.
Now, if you want to know if the person on the other end has opened
your message, that's a little trickier, but doable.
