It would help if you listed the Email Errors that you are getting.

For one thing, this line:

Code:

$this->email->to('$email');

You have $email in single quotes, which makes it a literal "$email" string instead of the contents of the variable. Remove the quotes.

Code:

$email = '[email protected]';
echo '$email';
//outputs: $email, not [email protected]
