Answer 1

There could be a possibility that there might be something wrong with the code and it would be throwing some error. Did you check in the session, what is the message you're receiving?
If there's an error, try checking what the error could possibly be. You may check the error by using the below code.
if($this->email->send()) {
echo 'Your Email has successfully been sent.';
}
else{
show_error($this->email->print_debugger());
}
