Muhammad, I'm not an expert on this but I'm fairly certain the only way to confirm an email is correct is with a confirmation email. There's really no other reliable way of doing it (that I know of). Additionally, emails aren't instant. It's entirely possible the email will take days to get to the recipient if it gets there at all. So don't expect a user to be sitting part way through the signup process waiting for an email.
As Michael said, have a look at how others a doing it.
