Is the recipient has your software installed on their machine also?

If not - I can't think of a way to do that.

In general, Both Email & SMS are guaranteed to either deliver your message, or return with an error. So you don't really need this functionality. you can toast the sender that the message was sent.

If the recipient will not get it, your user will get an indication from their email / sms sending facility.
