code is executing else block, i want to send mail to example@gmail.com and return user to the thankyou.html page after the mail function is executed.I am new to this php and i would highly appreciate the help thank you in advance. forget the below lines........

You don't actually specify where you want to send the email. You need to use the addAddress() method, as shown below. This method requires one parameter, but you may supply two - in the same way your setFrom() method has; first the target address, then an optional display name.

$mail = new PHPMailer;

// ...

$mail->setFrom($email, $name);
$mail->addAddress($to); // Add this method to specify a recipient 
$mail->Subject = $subject;
$mail->Body    = $message;
if($mail->send()) {
    // ...
}
// ...
